ABB High Performance S800S Miniature Circuit Breaker, 3-Pole, 63A, Type D, 690V AC, 250V DC, 50 kA 2CCS863001R0631 S803S-D63

ABB 2CCS863001R0631 S803S-D63 Miniature Circuit Breaker is a high-performance 3-pole circuit breaker with a rated current of 63A. It operates at a rated AC voltage of 690V and DC voltage of 250V, providing reliable circuit protection in a variety of industrial, residential, and commercial applications. Designed for DIN rail mounting, this compact breaker measures 81mm in width, 95mm in height, and 82.5mm in depth, making it suitable for installations where space is limited.

This breaker features a Type D tripping characteristic, ideal for protecting motors and similar inductive loads requiring high inrush current tolerance. The device combines electromagnetic and thermomagnetic tripping mechanisms, allowing it to respond rapidly to short circuits and overloads, respectively. The thermal element activates the breaker upon detecting excess current, preventing circuit damage through overload protection.

The toggle switch reset actuator allows for straightforward manual resetting after trip events. The breaker’s IP20 rating ensures adequate protection against solid foreign objects. Screw type terminals guarantee secure and reliable electrical connections.

Conforming to international standards IEC/EN 60898-1 and IEC/EN 60947-2, this breaker ensures high safety and quality compliance. Originating from Switzerland, it represents ABB’s commitment to durable, effective electrical protection.
