Gain secondary switching control of your electrical devices with this auxiliary contact block from Schneider Electric. The NO/NC (normally open/normally closed) configuration is ideal for switching devices such as start buttons or status indication lamps. When it's fixed to the primary contactor, it simultaneously changes state to trigger a signal to a logic controller, which in turn instructs the device to switch on or off. You'll find units like this one used in conjunction with other devices like circuit breakers to improve system safety and functionality.

• Compact, lightweight and easily attached to compatible contactors
• Flexible screw terminals fit a range of cable types
• Tested to 100,000 mechanical cycles for durability

• Relay logic circuits
