Why Choose the ABB MCRC013ATWD Mini Contactor Relay?
The ABB 1SAH220444R9900, type MCRC013ATWD, is a compact four-pole mini contactor relay designed for switching control signals and small electrical loads in residential, commercial and industrial applications. Part of ABB’s MCRC range, it provides reliable auxiliary switching performance in a space-saving design where control-panel space is limited.
The MCRC013ATWD features one normally open and three normally closed contacts (1NO + 3NC) and a DC-operated control circuit. Its extended operating-limits coil is rated for a 24 V DC control supply, while screw-terminal connections provide secure wiring for automation and control installations.
Designed for switching control signals up to 6 A at 240 V AC in AC-15 applications, the MCRC013ATWD combines compact dimensions with flexible installation options. It is suitable for wall or rail mounting and provides a practical solution where high switching performance is required but available panel space is restricted.
