The overcurrent protection threshold can be adjusted from 1A to 150A. The default setting is 125A. When the preset 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 125A. When the actual current exceeds the preset threshold, the protection trips after a programmable 0.1–30s delay.

The number of permitted overcurrent trips before automatic reclosing is locked out can be configured. The permitted number is 1–20 times, or the function can be disabled. Once 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 standards, the integrated leakage current function should not be regarded as a substitute for such a protective device unless its suitability and compliance have been separately confirmed.

• Overcurrent monitoring up to 150A adjustable in 1A increments.
• Automatic reclosing after 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: intended for installation inside an enclosed electrical distribution board.
• Maximum current 150A: the selected 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 SPD system for the building.

In an electrical distribution board, the relay can be used to monitor a single-phase load up to 150A. For example, the overcurrent threshold can be set to 125A. If the load current exceeds 125A for longer than the selected delay time, the relay disconnects the circuit. Once the cause of the fault has been removed and the parameters return to normal, power can be restored automatically after the preset recovery time.

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 it must be verified that no voltage is present at the terminals. Do not touch the terminals while the power is switched on. Before energizing the device, check all conductor and terminal connections. The device is intended for installation inside a protected electrical enclosure and must not be directly exposed to rain, intense sunlight or corrosive gases.
