ABB S800S-UC Series Miniature Circuit Breaker, 25A Current, 1000V dc Rated Voltage - 2CCS864001R1255

This miniature circuit breaker provides overcurrent protection for high-voltage DC systems and is intended for industrial electrical installations. It is a four-pole protective device with screw-type terminals and an I/O reset actuator, designed for mounting on DIN rails and operation where controlled interruption and isolation of DC circuits are required. Compliance with multiple international standards supports use in regulated environments.

Features and Benefits:

• 50kA breaking capacity protects systems from extreme fault currents
• UC-B tripping characteristic ensures defined response to overloads
• 4 poles enable simultaneous isolation of all circuit conductors
• IP20 enclosure rating allows use in protected indoor switchgear
• Screw terminals deliver secure conductor retention under vibration

Applications

• Suitable for photovoltaic string array DC protection
• Ideal for battery bank and energy storage systems
• Used with industrial DC distribution panels on DIN rail
• Can be used for traction system auxiliary circuits
• Suitable for commercial inverter and converter protection

What Terminal connection style is provided for conductor attachment?

It uses threaded screw terminals that permit torque-secured conductor clamping.

How is reset action implemented after a trip event?

A manual I/O actuator is provided for straightforward local resetting.

What international safety standards does the device meet?

It is compliant with IEC/EN 60947-2 and UL1077 among other listed approvals.

What is the device's rated fault interruption capability?

The unit is specified to interrupt up to 50kA of fault current.

How many poles are incorporated for circuit segregation?

The design includes four poles for complete multi-conductor isolation.
