Circuit breaker noark Ex9BN 1P B6 – miniature single-pole B6, MPN 100004

Miniature circuit breaker noark Ex9BN 1P B6 is a single-pole protection device with a B6 tripping characteristic designed for overcurrent and short-circuit protection in residential and light commercial electrical installations. The device is intended for DIN-rail mounting and provides reliable protection for individual circuits such as lighting, socket outlets and small appliances while preserving a compact footprint suitable for distribution boards with limited space.

Advantages

The noark Ex9BN 1P B6 features a B-type curve that ensures fast response to short-circuit currents produced by resistive loads and common household equipment, reducing the risk of conductor overheating. Its single-pole configuration simplifies installation for phase-only protection and conserves space in the panel. The breaker is built to standard dimensions for mounting on a standard DIN rail, allowing straightforward replacement or integration into existing switchgear.

Suitable for

• Protection of lighting circuits in residential and commercial premises
• Overcurrent protection for socket outlet circuits powering small appliances
• Individual circuit protection in distribution boards with limited space
• Upgrades or replacements in single-phase installations

Key specifications

• Poles: single-pole
• Tripping characteristic: B (suitable for resistive and general household loads)
• Rated current: 6 A
• Mounting: standard DIN-rail (TS35) compatible
• Application: overcurrent and short-circuit protection for lighting, sockets and small appliances
• Compact form factor for space-efficient distribution boards

How to use

Install the breaker on a standard 35 mm DIN rail inside the distribution board and connect the phase conductor to the breaker’s input terminal and the load conductor to the output terminal, following local wiring regulations. Ensure the installation is performed with the power disconnected and by a qualified electrician. After wiring, switch the device on and test the protected circuit for correct operation. Replace the device if it shows signs of mechanical damage or repeated nuisance tripping that cannot be resolved by correcting the circuit fault.

Usage recommendations

Use the noark Ex9BN 1P B6 on circuits where a 6 A rated, B-characteristic breaker is appropriate. Verify coordination with upstream protection and downstream conductors to ensure thermal and short-circuit protection limits are not exceeded. Periodically inspect terminal tightness and the breaker’s mechanical condition as part of routine electrical maintenance.
