Want to add snappy signalling to your system? Loop in this ABB auxiliary contact. It attaches to a contactor and works as part of a larger system to notify a controller when the contactor switches. With its instantaneous contacts, the device instantly opens and closes its circuit to send signals in a flash. Installation is trouble-free, as the unit slots onto a contactor's front plate. There's no need to worry about handling wires, thanks to screw terminals that keep your fingers clear while securing conductors.

• Handles up to 1,200 cycles an hour to keep up with fast-switching systems
• Accepts wires sized between 0.75 and 2.5mm² for versatile installation
• Tackles surge voltages up to 6kV, cutting the risk of hardware damage from electrical hazards
• Insulating plastic body minimises exposure to hazardous loads for safe handling

• Automated assembly lines
• Packing plants
• Automotive industry

Control devices oversee complex setups. By telling yours when a contactor has switched, it can tell other linked components to turn on or off, which keeps your automated process running without a glitch.
