1SFA611612R1001

The ABB 1SFA611612R1001 MCBL-01 Micro Switch Contact Block is a compact industrial control accessory designed to provide reliable electrical switching in compatible ABB modular pilot-device assemblies. Manufactured by ABB, this contact block features one normally closed (1 NC) contact that remains closed under normal, unactuated conditions and opens when operated by a compatible control mechanism. Its design makes it suitable for low-power control circuits, electrical signaling applications and industrial automation systems requiring a normally closed switching contact.

The ABB MCBL-01 is designed for front mounting with a compatible three-position holder in ABB's modular pilot-device range. Its compact housing allows convenient integration into electrical control panels, machine operating stations and industrial control equipment. The micro switch mechanism supports mechanical actuation by compatible push-button, selector-switch or joystick operators, depending on the assembly configuration. Screw terminals provide a practical connection method for control wiring, while the modular design allows straightforward installation and replacement during maintenance.
