## Summary description

Noark Ex9L-N residual current circuit breaker (RCCB) 4-pole, 40 A rated current, Type A residual current sensitivity, 100 mA trip threshold. Designed to detect earth/leakage currents and disconnect supply to protect people and equipment. Suitable for three-phase installations requiring AC and pulsating DC fault detection in residential, commercial, or light industrial distribution boards.

## Long description

Noark Ex9L-N residual current circuit breaker 4P 40A Type A 100 mA is a four-pole RCCB designed to detect earth leakage and disconnect supply in three-phase systems. It provides residual current protection with Type A sensitivity, capable of detecting AC and pulsating DC faults. The device is intended for mounting in distribution boards for residential, commercial, or light industrial installations where coordinated protection of personnel and equipment is required.
Advantages
The breaker offers selective disconnection of supply during earth-fault conditions with a rated current of 40 A and a trip threshold of 100 mA, improving safety in three-phase circuits. Type A sensitivity ensures detection of both alternating and pulsating direct residual currents. The four-pole format allows neutral protection in synchronized three-phase systems, and the modular design enables easy installation into standard DIN-rail distribution enclosures.
Suitable for
Three-phase residential and small commercial distribution boards
Circuits with electronic equipment where pulsating DC leakage may occur
Protection of sub-distribution boards and motor control feeders in light industrial settings
Key specifications
Number of poles: 4
Rated current: 40 A
Residual current type: Type A (AC and pulsating DC detection)
Trip sensitivity: 100 mA
Mounting: DIN-rail compatible modular housing
How to use
Install the breaker into a compatible DIN-rail distribution board following applicable electrical standards and local regulations. Connect the three phase conductors and neutral to the corresponding terminals, and secure the protective earth according to the switchboard layout. Ensure the supply is isolated before connecting or disconnecting the device. After installation, restore power and test the residual current operation using an appropriate testing procedure or tester to verify correct trip performance at the specified sensitivity.
Usage recommendations
Place this residual current breaker in circuits where 100 mA sensitivity is suitable for selective protection rather than direct human fault protection; combine with upstream and downstream protective devices and conduct periodic testing and inspection to maintain reliable operation.
