## Summary description

Noark Ex9BL-N is a 1P+N residual current circuit breaker combined with overcurrent protection (B10 characteristic, 10 A rated for overcurrent tripping) and 30 mA residual current sensitivity. Designed to protect circuits against earth leakage and overload/short-circuit, it is suitable for residential and light commercial installations where combined RCD and MCB functions are required.

## Long description

Noark Ex9BL-N is a combined residual current device and miniature circuit breaker in a 1P+N configuration with B10 tripping characteristic and 30 mA residual current sensitivity. It integrates earth-leakage protection and overcurrent protection in a single modular unit designed for DIN-rail mounting. The device is intended to interrupt supply in case of dangerous leakage currents or when overloads and short circuits occur, offering compact protection for single-phase circuits in domestic and light-commercial electrical installations.
Advantages
The combined RCD+MCB construction reduces the number of devices and wiring required in the distribution board, saving space while providing both residual current and overcurrent protection in one enclosure. B10 characteristic ensures selective tripping for typical lighting and small appliance circuits, and the 30 mA sensitivity meets common personal protection standards against electric shock. The modular form factor is compatible with standard DIN-rail systems, simplifying installation and maintenance.
Suitable for
Single-phase residential circuits supplying lighting and sockets
Small commercial or office circuits with mixed loads
Distribution boards where space-saving combined protection is required
Replacement or upgrade of separate RCD and MCB units
Key specifications
Configuration: 1 pole + neutral (1P+N)
Overcurrent tripping characteristic: B10 (suitable for moderate inrush currents)
Residual current sensitivity: 30 mA (earth-leakage protection)
Function: Combined residual current device (RCD) and miniature circuit breaker (MCB)
Mounting: DIN-rail compatible modular enclosure
Rated current for overcurrent protection: 10 A
How to use
Install the Noark Ex9BL-N on a standard 35 mm DIN rail inside the consumer unit according to local electrical codes and the manufacturer's wiring diagram. Connect the phase conductor to the line terminal and the neutral conductor to the neutral terminal, ensuring tight and secure terminations. Use the device as the protective element for a single-phase circuit; it will trip on residual current above 30 mA or on overcurrent conditions consistent with a B10, 10 A breaker. After tripping, verify the cause before resetting the device by manually switching it back to the ON position.
Usage recommendations
Verify compatibility with the existing distribution board and conductor sizes prior to installation. Use the Noark Ex9BL-N for circuits where personal protection against electric shock is required and where a 10 A B-curve breaker provides appropriate selectivity. Do not use the device as a primary disconnect for maintenance without following lockout/tagout and local safety procedures.
