Residual Current Circuit Breaker Noark EX9L-N 4P 40A 30mA 6kA (MPN 108362)
Noark EX9L-N residual current circuit breaker is a 4-pole device rated for 40 A continuous current with a residual operating current of 30 mA and a rated breaking capacity of 6 kA. Type A sensitivity ensures detection and disconnection for alternating and pulsating DC residual currents. The unit is designed for installation in distribution boards to provide earth-fault and electric shock protection in residential, commercial and light industrial electrical installations.
The Noark EX9L-N offers selective and standard-compliant residual current protection with Type A detection, fast disconnection at 30 mA residual current and reliable performance up to a 6 kA fault breaking capacity. Its 4-pole design allows use in three-phase systems with neutral, while compact modular dimensions permit integration into standard DIN-rail distribution boards. The device is suitable for mixed-use environments where protection against alternating and pulsating DC leakage currents is required.
Install the Noark EX9L-N in the distribution board on a standard DIN rail according to local electrical codes. Connect line and neutral conductors to the corresponding terminals ensuring correct phase sequence for three-phase systems. Verify tightening torque of terminal screws as specified by the installer documentation and ensure proper upstream overcurrent protection is in place. Perform functional testing after installation by using appropriate test procedures for residual current devices and verify that the breaker trips at an appropriate test current or using the integrated test button if present.
Use this device as part of a complete protection scheme: combine the RCCB with suitable overcurrent protection devices, respect the rated current and breaking capacity limits, and perform periodic testing and inspection according to applicable regulations and manufacturer guidance to ensure reliable earth-fault protection.
