The IMO MB12-S-0124 is a compact and reliable mini contactor designed for motor control, load switching and industrial automation applications. Manufactured by IMO Precision Controls, it provides dependable switching performance in control panels, machinery systems and OEM electrical assemblies where space-saving installation is important.
This mini contactor features 3 normally open main contacts, a 5.5 kW motor rating and a 12 A AC-3 current rating. It also includes a 1 normally closed auxiliary contact and a 24 V AC coil, making it suitable for low voltage AC control circuits used in machinery, automation and motor control systems.
With screw terminal connections, DIN rail mounting and a compact miniature contactor format, the IMO MB12-S-0124 is ideal for panel builders, machine builders and maintenance engineers who require reliable operation, straightforward wiring and a small footprint for motor control and auxiliary switching applications.
Mini contactors such as the IMO MB12-S-0124 are used to switch motors and electrical loads from a control signal, allowing equipment to be operated by pushbuttons, relays, PLC outputs, timers or automation systems. Their compact size makes them especially useful in machinery panels and control cabinets where space is limited.
The 3 pole main contact arrangement provides dependable switching for suitable three-phase motor circuits, while the built-in normally closed auxiliary contact can be used for feedback, interlocking or control logic. The 24 V AC coil makes this model suitable for low voltage control circuits commonly used in machinery and automation systems.
