Siemens SIRIUS Innovation Auxiliary Contact, NO/NC - 3RV2 Series - 3RV2901-1E
Need a reliable auxiliary contact for use in conjunction with primary contactors, circuit breakers or relays? This double-contact block from Siemens' SIRIUS Innovation range is designed for easy integration into distributed systems. Its two contacts are set up as 1NC (normally closed) + 1NO (normally open), so it's suitable for use with industrial power relays and emergency-stop switches. The double-pole configuration means it can control two circuits, while the contact voltage rating of 60V DC / 230V AC makes it compatible with the UK mains supply.
• Operating temperature range of -20°C to +60°C to withstand harsh conditions
• Screw terminals to make quick and secure connections
• Plug-in mounting style for easy installation

How do auxiliary contacts work?
Auxiliary contacts work in tandem with the primary contacts. When the primary contacts change state, so do the auxiliary contacts. The auxiliary contacts pass the data from the circuit to a logic controller, which tells linked devices when to turn on or off.
Where are auxiliary contacts used?
Auxiliary contacts are commonly found in the start buttons of pushbutton controllers, as well as in relay circuits and electric motors.
