About DIN-Rail Miniature Circuit Breakers

Mount these miniature circuit breakers on DIN rails. Miniature breakers require less mounting space than standard breakers. Mounting on DIN rails allows you to easily add, move and remove circuit breakers as needed without having to add new panelboards or load centers.

These breakers are UL1077 or UL489 listed and are classified according to their fault over-current tripping range. All circuit breakers must be used with a compatible panelboard or load center.

These 5SJ4-series miniature circuit breakers are suitable for general-purpose protection of distribution boards and control systems and cabinets. They are IEC/EN and UL489 rated, and can be used in HVAC systems and telecommunications applications.
