Product Description
This device is a motor protection circuit breaker engineered for reliable thermal and magnetic protection of three-phase motors. It supports operation up to 690 V AC/DC with a continuous current rating of 5 A and provides Class 10 motor protection for dependable trip characteristics. Designed in the S0 frame size, it integrates screw-type terminals and mounts via screws or snap-on to a 35 mm DIN rail, simplifying panel installation and service. The breaker is rated to withstand surge voltages up to 6 kV and offers short-circuit protection with a release setting at 65 A, supporting systems up to 100 kA interrupt capability when paired appropriately. With an IP20 protection class, it is suitable for enclosed applications and operates across -20 to +60 °C ambient conditions, meeting common industrial requirements. Typical uses include motor control centers, machine panels, and distributed automation cabinets where compact, dependable motor protection is required. Packaging dimensions are 102 x 49 x 102 mm with a net weight around 0.36 kg, reflecting a compact footprint for dense assemblies.
