ABB S800S-UC Series Miniature Circuit Breaker, 125A Current, 250V dc Rated Voltage - 2CCS861001R1647

This miniature circuit breaker provides overcurrent protection for DC systems and is designed for panel and DIN-rail installations. It is a single-pole protective device with a dedicated reset I/O actuator intended for repeatable manual operation. The unit meets multiple international safety and materials standards and is intended for industrial distribution and control environments where DC protection and a Compact footprint are required.

Features and Benefits:

• 50kA breaking capacity reduces risk from high fault currents
• UC-K tripping characteristic ensures defined response to overloads
• 125A current rating supports high-current DC circuits
• Screw Terminal offers secure conductor clamping for vibration resistance
• IP20 enclosure allows safe handling in enclosed switchgear

Applications

• Suitable for protecting 250Vdc industrial control circuits
• Ideal for use in motor drive feed protection
• Can be used for battery bank overcurrent protection
• Used with distribution modules in control panels
• Suitable for renewable energy collection string protection
