Featuring a particularly compact design, the 3VL molded-case circuit breakers meet all requirements placed upon space-saving electrical distribution systems – in a power range from 16 A to 1600 A.

Depending on the individual requirements, the universal and communication-capable circuit breakers are available for system and motor protection, for starter combinations or as non-automatic circuit breakers. The corresponding releases are optionally available as thermal-magnetic (16 A to 630 A) or electronic (63 A to 1600 A) trip units. With only two ranges of internal accessories, 3VL circuit breakers offer maximum versatility with minimum expenditures.
