Why Choose the ABB MCRA013ATM Mini Contactor Relay?
The ABB 1SAH220417R9900, type MCRA013ATM, 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 MCRA range, it provides reliable auxiliary switching performance in a space-saving format for electrical control panels.
The MCRA013ATM features one normally open and three normally closed contacts (1NO + 3NC). Its AC-operated control circuit uses a 208–220 V AC rated control voltage at 60 Hz, while screw-terminal connections provide secure integration into control and automation systems.
Designed for switching control signals up to 6 A at 240 V AC in AC-15 applications, the MCRA013ATM combines compact dimensions with flexible installation options. It is suitable for rail or wall mounting and provides a practical solution where multiple auxiliary switching functions are required in a limited panel space.
