The overcurrent protection threshold can be adjusted from 1A to 125A. The default setting is 100A. 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 100A. When the actual current exceeds the configured threshold, the protection trips after a programmable 0.1–30s delay.

The number of permitted overcurrent trips before automatic reclosing is blocked can be configured. The permitted number is 1–20 trips, or the function can be disabled. Once the selected number of trips is exceeded, the circuit remains disconnected and 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 replacement for such a protective device unless its suitability and compliance have been separately confirmed.

• Overcurrent control up to 125A adjustable in 1A increments.
• Automatic reclosing after acceptable mains parameters are restored.
• Overvoltage and undervoltage protection with programmable thresholds.
• Leakage current monitoring within a 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 125A: the configured protection threshold and conductor cross-section must correspond to the actual circuit load.
• Operating temperature up to +40°C: suitable environmental conditions must be maintained inside the electrical enclosure.
• Leakage protection function should not be regarded as a replacement 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 125A. For example, the overcurrent threshold can be set to 80A. If the load current exceeds 80A 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 automatically restored after the configured recovery delay.

Yes. The digital display shows the operating voltage and load current.

Yes. Up to 999 records can be stored in the fault history.

Yes. The password can be set within the 000–999 range.

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 it must be verified that no voltage is present at the terminals. Do not touch the terminals while the power is switched on. Before energising the device, check all wiring 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.
