The overcurrent protection threshold can be adjusted from 1A to 100A. The default setting is 80A. When the set current is exceeded, the load is disconnected after the selected 0.1–30s delay.

The overcurrent protection threshold can be set in 1A increments. The default value is 80A. When the actual current exceeds the preset threshold, protection trips after a programmable 0.1–30s delay.

It is possible to set the number of overcurrent trips permitted before automatic reclosing is blocked. The permitted number is 1–20 trips, or the function can be disabled. When the selected number of trips is exceeded, the circuit remains disconnected and a manual reset is required.

Where a separate RCD or RCBO is required by the electrical design or applicable regulations, the integrated leakage current function should not be regarded as a substitute for such a protective device unless its suitability and compliance for that purpose have been separately confirmed.

• Overcurrent monitoring up to 100A with adjustment in 1A increments.
• Automatic reclosing when normal mains parameters are restored.
• Overvoltage and undervoltage protection with programmable thresholds.
• Leakage current monitoring within the 10–100mA range.
• Temperature protection adjustable up to 120°C.
• Digital voltage and current display.
• Adjustable protection delays allow operation to be adapted to different loads.
• Fault history for up to 999 records.
• Password protection for parameter settings.
• DIN rail mounting for convenient integration into an electrical distribution board.

• IP20: designed for installation inside an enclosed electrical distribution board.
• Maximum current 100A: the protection threshold and conductor cross-section must correspond to the actual circuit load.
• Operating temperature up to +40°C: suitable conditions must be maintained inside the electrical enclosure.
• Leakage current protection should not be considered a substitute for an RCD / RCBO without separate confirmation of suitability.
• Class III impulse overvoltage protection does not replace a complete coordinated building SPD system.

In an electrical distribution board, the relay is used to monitor a single-phase load of up to 100A. For example, the overcurrent threshold can be set to 63A. If the load current exceeds 63A for longer than the selected delay time, the relay disconnects the circuit. Once the cause of the fault has been eliminated and the parameters return to normal, power can be automatically restored after the preset recovery delay.

Yes. The input circuit must be protected by a correctly selected circuit breaker.

The device must be installed by a qualified electrical professional. A correctly selected circuit breaker must be installed on the input side. Before installation or maintenance work, all power sources must be disconnected and the absence of voltage at the terminals must be verified. Do not touch the terminals while the power supply is switched on. Before energising the device, check all wiring and terminal connections. The device is designed for installation inside a protected electrical enclosure and must not be directly exposed to rain, intense sunlight or corrosive gases.
