## Summary description

Residual current circuit breaker Noark Ex9L-N, 4-pole, rated 25 A with 30 mA residual current sensitivity. Designed to detect leakage currents and disconnect supply to protect against electric shock and fire risk. Suitable for residential and light commercial installations, distribution boards and circuits requiring earth-fault protection.

## Long description

The Noark Ex9L-N residual current circuit breaker is a 4-pole device rated at 25 A with 30 mA residual current sensitivity. It is engineered to detect leakage currents and disconnect the supply quickly to reduce the risk of electric shock and fire. The breaker is suitable for installation in residential and light commercial distribution boards where reliable earth-fault protection is required for multiple-phase circuits.
Advantages
The Ex9L-N provides selective protection for four-pole systems with a compact form factor that fits standard DIN-rail panels. Its 30 mA sensitivity balances safety and nuisance tripping, offering effective personal protection from electric shock while minimising unnecessary interruptions. The device is designed for straightforward integration into existing electrical installations and for continuous operation in typical building environments.
Suitable for
Residential main and sub-distribution boards
Light commercial premises and small offices
Three-phase circuits with neutral conductor
Circuits requiring protection against earth leakage and shock
Key specifications
Number of poles: 4
Rated current: 25 A
Residual current sensitivity: 30 mA
Function: residual current detection and disconnection
Mounting: DIN-rail compatible
Typical applications: earth-fault protection for multi-phase circuits
How to use
Install the device on a standard DIN-rail inside the distribution board and connect phase and neutral conductors according to the electrical schematic and local wiring regulations. Ensure the breaker is accessible for operation and testing. After installation, test the residual current function using the built-in test button or a certified RCD tester to confirm correct operation and trip performance at the rated residual current. Follow applicable national electrical codes for connection and protective device coordination.
Usage recommendations
Use the Ex9L-N in circuits where 30 mA sensitivity is appropriate for personal protection. Periodically test the device at least every six months or according to local regulations to ensure reliable operation. Coordinate this residual current device with upstream and downstream protective devices to avoid unintended selective tripping in multi-device arrangements.
