## Long description

Noark Ex9L-N residual current circuit breaker is a 4-pole protective device with a rated current of 40 A and residual current sensitivity of 30 mA. It is designed to detect earth leakage and rapidly interrupt power to reduce the risk of electric shock and fire. The device is suitable for use in residential and light commercial electrical installations where reliable fault detection, personnel safety and circuit isolation are required.
Advantages
The Ex9L-N combines four-pole protection with a 30 mA trip threshold for reliable detection of dangerous leakage currents. Its 40 A rated current supports typical household and small business circuits while providing selective and fast disconnection of faulty circuits. The device is compact and intended for integration into standard distribution boards, offering straightforward installation and maintenance. It is designed to operate consistently under normal load conditions and to provide stable performance over repeated trip cycles.
Suitable for
 Protection of residential electrical circuits and branch circuits
 Light commercial and small office electrical installations
 Protection of circuits supplying kitchens, bathrooms and other areas with increased shock risk
 Selective disconnection of multiphase circuits requiring earth leakage protection
Key specifications
 Number of poles: 4-pole protection
 Rated current: 40 A
 Residual current sensitivity: 30 mA
 Function: Earth leakage detection and circuit interruption
 Application: Residential and light commercial distribution boards
How to use
Install the Noark Ex9L-N in the distribution board according to local electrical codes and wiring diagrams. Connect the incoming supply to the line terminals and the outgoing circuits to the load terminals, ensuring correct phase and neutral connections for four-pole installation. Verify that circuit labeling and upstream protection are coordinated. After installation, perform insulation and functional tests and check that the device trips at the expected residual current. Regularly test the device using the test button or by professional measurement to confirm operational readiness.
Usage recommendations
Use the breaker within its rated current and sensitivity limits and follow national wiring regulations. Periodically test residual current operation and inspect connections for tightness and corrosion. For complex installations or where additional selectivity is required, consult a qualified electrician to coordinate upstream and downstream protective devices and ensure proper discrimination.
