  • Product description

    Automatic Aerosol Fire Suppression Device | 15 g | 0.15 m³ | 170 °C Activation | DIN | A/B/C/E | ES-QRR0.015G/S-CFLC

    ES-QRR0.015G/S-CFLC is a compact autonomous aerosol fire suppression module, mounted on a DIN rail directly inside an electrical or automation enclosure. The device contains 15 g of aerosol-generating compound, and the protected enclosed volume reaches up to 0.15 m³. It activates automatically when the thermal activation line heats up to 170 ±10 °C – no power supply, no controller, no external sensors required.

    Main idea:
    Most fires in electrical panels start at an overheated terminal, contactor, or conductor, and stay undetected inside a closed enclosure for the first few minutes. A general room fire alarm picks this up late, and the fire extinguisher hangs out in the corridor. The ES-QRR0.015G/S-CFLC module is installed right at the source of risk and extinguishes locally, before the flame spreads beyond the enclosure. It is an inexpensive protection measure for expensive equipment: meters, automation controllers, frequency converters, UPS units, and server cabinet components.
    Suppression agent
    15 g aerosol-generating compound
    Protected volume
    up to 0.15 m³ (100 g/m³ density)
    Activation
    thermal line, 170 ±10 °C, autonomous
    Standard / installation
    EN 15276-1:2019; DIN rail, 66×79×19 mm

    Operating principle

    The module is mounted inside the protected enclosed space on a DIN rail, and the thermal activation line is routed over the most likely fire zone. Under normal conditions the device is completely passive – it uses no energy and requires no connection to any control system. If a fire breaks out inside the enclosure, the temperature rises, and once the activation line reaches 170 ±10 °C, the aerosol generator is triggered.

    Once triggered, the generator releases the fire-suppressing aerosol within a few seconds – fine particles of potassium compounds that break the combustion chain reaction. The design suppression density is 100 g/m³, so 15 g of agent is sufficient for up to 0.15 m³ of enclosed volume. The aerosol is effective only in an enclosed space: if the enclosure door is open or there are large ventilation openings, the concentration cannot be maintained and the suppression effect is reduced.

    What are the benefits of the ES-QRR0.015G/S-CFLC?
    It provides automatic fire protection in places where other measures are practically impossible to install – in a small electrical enclosure, an automation box, or an equipment cabinet. No power supply, piping, or alarm control panel is needed: it only needs to be screwed onto the DIN rail and the activation line routed correctly. The aerosol is non-conductive and leaves no water or powder residue, so after activation the equipment can often be cleaned and continue in use.

    Key features

    • Automatic thermal activation – triggers without human intervention, power, or a controller, once the line reaches 170 ±10 °C.
    • Local suppression at the source – the aerosol fills the enclosed volume up to 0.15 m³ and suppresses the flame within the first seconds.
    • DIN rail mounting – the 66×79×19 mm housing takes up about as much space as a few modular circuit breakers.
    • Classes A, B, C, E – suitable for fires involving solid, liquid, gaseous materials, and electrical equipment.
    • Wide operating range – from −50 to +90 °C and up to 95 % RH: suitable for outdoor enclosures, cold rooms, production areas.
    • 10-year service life – no periodic refilling or pressure checking, unlike powder or gas fire extinguishers.

    Where is it used?

    • Electrical distribution boards in apartment buildings, offices, and private homes.
    • Automation and control cabinets with PLCs, frequency converters, relays.
    • Protection of solar inverter, DC panel, and battery box enclosures.
    • Server, telecommunications, and network equipment cabinets.
    • UPS and battery cabinets, charging station panels.
    • Outdoor enclosures, containerized and compact electrical installations.
    • Production line machine control panels and power boards.
    • Elevator, ventilation, and heating automation boxes.

    Application by need

    For residential users.
    A home's main or distribution board often stands in a hallway, garage, or basement, where a fire is noticed late. A single module on the DIN rail provides automatic protection with no maintenance for 10 years – install it and forget about it.
    For businesses and industry.
    Automation cabinets concentrate expensive equipment, and downtime costs more than the equipment itself. The module extinguishes the fire at its source before it spreads to cable runs, reducing downtime and insurance risk. Larger enclosures use several modules or higher-capacity versions.
    For electricians / engineers.
    This is a simple way to add fire protection to a project without a separate suppression system: no power, signals, piping, or control panel required. It is important to correctly calculate the enclosed enclosure volume (no more than 0.15 m³ per module) and route the activation line over the risk zone.

    Practical application

    An office building floor panel measuring 500×400×220 mm has an internal volume of about 0.044 m³. It houses 36 modular circuit breakers, contactors, and lighting control relays. A single ES-QRR0.015G/S-CFLC module, rated for up to 0.15 m³, covers this volume with triple the margin. The device is screwed onto a free section of DIN rail (2–3 module widths), and the activation line is routed over the row of breakers and contactors. If a contactor contact overheats and the insulation catches fire, the line reaches 170 °C, the module activates, and the aerosol fills the enclosed panel within seconds – the fire is suppressed before the cable entries burn through.

    Pros

    • Fully autonomous – no power supply, controller, sensors, or alarm control panel required.
    • Compact – 66×79×19 mm, 85 g; fits even the smallest enclosures.
    • Quick installation – on the DIN rail in a few minutes, with no tools needed for the suppression system.
    • Does not harm electronics – the aerosol is non-conductive, with no water or powder residue.
    • Wide range – from −50 to +90 °C, up to 95 % RH.
    • Long service life – 10 years with no refilling or pressure checking; EN 15276-1:2019, CE, TÜV, RoHS.

    Cons / limitations

    • Protects only up to 0.15 m³ of enclosed volume – a larger enclosure requires several modules or a higher-capacity version.
    • Effective only in an enclosed space – an open door or large ventilation openings reduce the aerosol concentration.
    • Single-use – once activated, the module must be replaced with a new one.
    • No signal output – activation is not reported to a control or alarm system; periodic inspection is required.
    • Activation depends on the placement of the activation line – an incorrectly routed line may trigger too late.

    Safety and installation notes

    • Before installation, calculate the enclosed enclosure volume (length × width × depth) and make sure it does not exceed 0.15 m³ per module.
    • Route the activation line over the highest-risk components – contactors, terminal blocks, power breakers – and secure it so it does not touch moving parts.
    • Do not install near heat-emitting elements that may reach close to 170 °C under normal conditions, to avoid false activation.
    • Make sure the enclosure door is closed and sealed – this is essential for maintaining the suppression concentration.
    • After activation, switch off the power supply, ventilate the enclosure, and inspect the equipment before restarting; replace the module with a new one.
    • The module does not replace the building's fire alarm system and fire extinguishers – it is an additional local protection measure in accordance with the site's fire safety requirements.
