## Long description

JUNG 505 KOU 5 1P is a single-pole circuit breaker switch for AC installations rated at 250 V. Designed for residential and commercial electrical systems, this 1-pole device provides reliable switching and circuit isolation for lighting circuits, control circuits and small appliances. The switch supports panel or modular mounting where a compact 1P 250 V unit is required and includes features that simplify wiring and lamp replacement.
Advantages
The switch offers screwless terminals that accept conductors up to 2.5 mm², reducing installation time and ensuring a secure connection. A neutral conductor is required for correct operation, and the design allows lamps to be exchanged without disconnecting the mains. The unit also supports coloured glow lamps for visual signalling.

How to use
