ABB S800S-UC Series Miniature Circuit Breaker, 80A Current, 750V dc Rated DC Voltage - 2CCS863001R1805

This miniature circuit breaker provides overcurrent protection for three-pole DC systems and is designed for industrial control panels and power distribution assemblies. It offers a UC-B tripping characteristic for defined response to fault conditions and integrates a reset I/O actuator for straightforward manual switching.

Features and Benefits:

• 50kA breaking capacity gives robust fault interruption performance
• 80A current rating allows handling of high DC load currents
• Screw Terminal design simplifies secure conductor termination
• IP20 enclosure rating permits indoor protected installations
• UC-B tripping characteristic supports predictable fault response

Applications

• Suitable for DC power distribution in solar arrays
• Used with battery banks in backup power systems
• Ideal for three-phase DC motor control panels
• Suitable for industrial control cabinets on DIN rail
• Used for protection in telecommunication power racks

How many poles does it provide and why is that important?

It uses three poles to simultaneously disconnect all conductors in three-phase or multi-wire DC systems, ensuring coordinated protection.

What type of actuator is fitted for manual operation?

A reset I/O actuator is provided to allow clear on/off manoeuvres and straightforward resetting after a trip.

Which approvals indicate environmental and safety compliance?

It carries RoHS and REACH declarations alongside UL 1077 and IEC/EN 60947-2 recognitions, indicating adherence to chemical and electrical safety criteria.

What Terminal connection method is used and what is the benefit?

Screw terminals are employed to secure conductors with mechanical clamping, supporting reliable electrical contact in vibration-prone environments.
