The B7-30-10-01 is a compact 3-pole AC mini contactor from ABB designed for space-constrained applications requiring reliable power switching. It is rated for 5.5 kW at 400 V AC-3 (IEC) and 20 A AC-1 at 400 V with a coil consumption of 3.5 W, featuring one normally open (1 N.O.) auxiliary contact. The contactor operates with a 24 V AC control supply and is equipped with screw terminals for secure connection. Its flat, compact design makes it ideal for modular and space-limited installations, supporting motor loads up to 5.5 kW and resistive loads up to 20 A. Common applications include motor control, power distribution, and auxiliary circuit switching in industrial automation and compact control panels.
