ABB S800S-UC Series Miniature Circuit Breaker, 100A Current, 750V dc Rated DC Voltage - 2CCS863001R1825

This miniature circuit breaker provides overcurrent protection for three-phase DC installations. It is designed to interrupt fault currents and protect downstream circuits in industrial control environments. The unit accommodates screw-type connections and includes a manual I/O reset actuator for straightforward operation.

Features and Benefits:

• 100A Current Rating delivers high continuous current capacity
• 50kA Breaking Capacity limits damage during short circuits
• UC-B Tripping Characteristic offers defined response to fault types
• 3‑Pole configuration ensures simultaneous pole disconnection
• IP20 Protection rating allows safe indoor panel mounting

Applications

• Suitable for photovoltaic string protection in high-voltage systems
• Ideal for battery array isolation in DC power installations
• Used with industrial control panels requiring three-pole protection
• Can be used for commercial energy storage safety circuits

What Terminal arrangement does it use?

It employs screw terminals for secure conductor clamping compatible with standard busbar and cable terminations.

How is operator reset handled after a trip?

A manual I/O actuator allows clear on/off positioning and manual reset of the tripped mechanism.

Which standards and approvals relate to its qualification?

It complies with IEC/EN 60947-2 and carries approvals including UL 1077, REACH, RoHS, ETIM 9 EC000042 and CMRT.

What are the enclosure dimensions for panel layout?

The device has a height of 95 mm, width of 81 mm and depth of 82.5 mm.
