Boost the switching capabilities of your relay and power contactors with this auxiliary contact from Siemens. It has four contacts that mirror the operation of your contactor, making it handy for signalling and monitoring tasks.

And with no more than one faulty switch in 100 million, you can depend on the contact to do the job reliably. The auxiliary contact has compact dimensions of 37.5 (H) x 36 (W) x 43.7mm (D), helping you pack more modules into your control cabinet. Use it alongside a motor starter protector, overload relay and surge suppression module to keep your equipment working safely.
