Why Choose the ABB SH202-B6 Miniature Circuit Breaker?
The ABB SH202-B6 is a compact and reliable 2-pole miniature circuit breaker (MCB) designed to provide overload and short-circuit protection for low-voltage electrical circuits. As part of the established ABB SH200 MCB series, it is a current-limiting circuit breaker combining delayed thermal tripping for overload protection with electromagnetic tripping for rapid protection against short circuits.
With a rated current of 6 A, a Type B tripping characteristic and a rated short-circuit breaking capacity of 6 kA at 230/400 V AC, the SH202-B6 is suited to circuits with relatively low inrush currents. Its B-curve characteristic makes it particularly appropriate for general residential and similar electrical loads where dependable overcurrent protection is required.
The SH202-B6 features a 2-pole configuration with two protected poles, enabling simultaneous switching and protection of two conductors. With a rated operational voltage of 400 V AC and compact dimensions of approximately 85 × 35 × 69 mm, it is designed for straightforward installation on DIN rail within consumer units, distribution boards and electrical enclosures.
