Siemens SIRIUS 3RT Size S2 3RT2 Contactor 110 V ac Coil 3-Pole 90 A 37 kW 1NO+1NC 690 V ac
Looking for a reliable switching solution to power up your electric circuit? Put this contactor from Siemens to the test. When it receives an electrical signal, it makes or breaks the circuit by causing the internal contacts to open or close. With a contact current of 90A and a power rating of 37kW, it packs the punch needed for heavy-duty equipment. As the unit’s resistant to mechanical shock, it’s a stable workmate you can depend on if things get shaky. Mounting it’s a cinch – simply snap it onto a DIN rail and use it to power everything from lighting fixtures to HVAC systems.

How does an auxiliary contact work?
An auxiliary contact is designed to carry out additional switching functions by monitoring the state of the main contact and changing state when it does. It’s typically attached directly to the primary switching mechanism.
