## Long description

Noark EX9B40J single-pole miniature circuit breaker rated at 20 A with Type B tripping characteristic and 6 kA breaking capacity is designed for overcurrent protection in residential and light commercial electrical installations. The device interrupts short-circuit and overload currents for lighting circuits, socket outlets and small appliances. Its slim, single-pole form factor fits standard DIN-rail distribution boards, allowing compact arrangement in consumer units and sub-distribution panels.
Advantages
The miniature circuit breaker offers selective and repeatable trip performance with a Type B characteristic suitable for general-purpose circuits with low inrush currents. With a rated current of 20 A and a 6 kA short-circuit breaking capacity, the device ensures safe disconnection under fault conditions while maintaining a compact footprint. The single-pole design reduces required panel space and simplifies wiring for phase-only protection in single-phase installations.
Suitable for
 Lighting circuits in residential and commercial premises
 Socket outlet protection for general household appliances
 Protection of small motors and equipment with low starting currents
 Compact DIN-rail distribution boards and consumer units
Key specifications
 Poles: single-pole (1P)
 Rated current: 20 A
 Tripping characteristic: Type B (instantaneous trip for 3–5x In)
 Breaking capacity: 6 kA (short-circuit interrupting capacity)
 Mounting: standard DIN-rail
 Application: overcurrent protection (short-circuit and overload)
 Typical use: single-phase circuits for lighting and sockets
How to use
Install the breaker on a standard DIN-rail inside a properly rated distribution board. Ensure the supply is isolated before making connections. Connect the phase conductor to the input terminal and the load conductor to the output terminal, observing correct torque settings recommended by the panel manufacturer. Close the device onto the rail until it clicks into place and restore supply to verify correct operation. Use the breaker as part of a complete protective system together with residual current devices and upstream coordination elements when required.
Usage recommendations
Use this Type B 20 A single-pole breaker for general lighting and socket circuits where inrush currents are low. Coordinate with upstream protection to maintain selectivity and verify compatibility with the distribution board's rated short-circuit capacity. Periodically inspect connections and terminals for tightness and signs of overheating.
