1SYS274012R0031

The ABB SB204M-D3 miniature circuit breaker (MCB), part number 1SYS274012R0031, belongs to the System pro M compact SB200M series. It is a current-limiting protective device designed to protect electrical circuits against overloads and short circuits. The device uses a thermal tripping mechanism for overload protection and an electromagnetic tripping mechanism for short-circuit protection.

This four-pole circuit breaker has a rated current of 3 A and a D-type tripping characteristic, making it suitable for applications where connected equipment may draw relatively high starting currents. It has a rated short-circuit breaking capacity of 10 kA and is designed for electrical installations in residential, commercial and industrial environments, subject to appropriate circuit design and applicable standards. It complies with IS/IEC 60898-1.
