Why Choose the ABB MC1AC00AT1 Mini Contactor?
The ABB 1SAL103005R9901, type MC1AC00AT1, is a compact four-pole mini contactor designed for controlling single-phase and three-phase loads in residential, commercial and industrial electrical applications. Its dimension-optimised construction provides reliable switching performance where electrical panel space is limited.
The MC1AC00AT1 features three normally open main contacts and one normally closed auxiliary contact (3NO + 1NC). Its 24 V AC control circuit and screw-terminal connections provide a practical switching solution for automation systems, machinery and electrical control installations.
With suitability for controlling loads up to 4 kW in AC-3 applications and switching up to 20 A at 690 V AC in AC-1 applications, the MC1AC00AT1 provides a compact alternative to larger contactors. Its rail or wall mounting capability allows flexible installation inside control panels and distribution assemblies.
