Hager SVN121 is a single-pole miniature circuit breaker designed to provide overcurrent protection and circuit isolation in residential and light-commercial electrical installations. With an IP20 enclosure rating, the device offers basic protection against accidental contact with live parts and is intended for installation in distribution boards where access is restricted. The unit includes a green LED indicator light for 230 VAC, allowing quick visual confirmation of status and aiding in fault identification during inspection or maintenance.

Advantages

The compact single-pole design saves space in distribution boards while delivering reliable overload and short-circuit protection for one phase. The IP20 rating ensures safe use in standard indoor electrical cabinets. The integrated green LED indicator for 230 VAC improves usability by indicating operational status without opening the enclosure. The breaker is compatible with common DIN-rail mounting systems and is suitable for typical wiring and load conditions found in homes and small commercial premises.
