Product description

The Siemens CFD63B200 is a robust Miniature Circuit Breaker (MCB) engineered for effective protection against overcurrents and short circuits. It features a B-curve tripping characteristic, suitable for loads with moderate inrush currents. With a significant 200A rated current and a 6kA breaking capacity, this breaker provides dependable safety for electrical circuits.

This circuit breaker is extensively applied in industrial settings, power distribution panels, and large commercial facilities to safeguard electrical systems. The B-curve makes it appropriate for circuits feeding lighting, heating elements, and some types of motor loads where a slight inrush current is typical.

Stanlo Automation, a veteran-owned supplier of surplus industrial parts, offers the Siemens CFD63B200. We pride ourselves on delivering quality components and exceptional service to ensure your operations are continuously protected and efficient.
