Residual current circuit breaker Noark Ex9L-N 2P 25A 30mA
Residual current circuit breaker Noark Ex9L-N 2P 25A 30mA
Noark Ex9L-N residual current circuit breaker, 2-pole, rated at 25 A with 30 mA residual current sensitivity, is intended to detect earth leakage and interrupt supply to prevent electric shock and reduce fire risk. The device is designed for use in residential and light-commercial distribution boards and consumer units to enhance electrical safety by disconnecting faulty circuits when leakage currents exceed the set threshold.
The breaker provides reliable detection of residual currents down to 30 mA and fast disconnection of the protected circuit, improving personal safety and lowering the likelihood of fire caused by insulation faults. Its two-pole design allows simultaneous disconnection of both phase and neutral conductors in single-phase circuits. The compact modular housing is suitable for DIN-rail mounting and integration into standard distribution boards, offering straightforward installation and maintenance.
Install the Noark Ex9L-N in the distribution board on a standard DIN rail, connecting phase and neutral conductors to the marked terminals in accordance with local wiring regulations. Ensure the device is accessible for testing and maintenance. After installation, verify correct operation by performing the built-in test procedure or following the manufacturer's recommended test method to confirm the RCD trips at the specified residual current. Regular periodic testing is advised to maintain protection effectiveness.
Use this residual current breaker in circuits where 30 mA sensitivity is appropriate for personal protection. Avoid using it for selective discrimination in complex systems without coordination studies. Follow local electrical codes for installation, and replace or service the device if it fails functional tests or shows signs of damage.
