Thermal Circuit Breaker / Switch Series 3131
Description
Combination of single pole circuit breaker and ON/OFF switch with
soft-touch rocker actuation. Contoured rockers are available with a
choice of colours and legends, with optional illumination. The 3131 is
sealed to provide IP66 rated front of panel water splash protection.
It meets the requirements of circuit breaker standard EN 60934 (IEC
60934): S type, TO.
Typical applications
Motor protection, transformer protection, household appliances and office
equipment, electrical tools, mobile homes, watercraft, construction
vehicles, medical equipment.
