The unit uses a 115 V coil (nominal 115 VAC, compatible with 110–120 VAC control systems) to pull in its main contacts, enabling L1-L3 to connect to T1-T3, and it is rated to carry up to 22 A at up to 600 VAC. This makes it suitable for controlling standard industrial motors, pumps, fans, and conveyors in 50\/60 Hz environments. The 3TB43 family can be ordered with various auxiliary contact configurations; for example, the 3TB43-17-0A-J2 variant includes two normally open and two normally closed auxiliary contacts, which supports interlocking, signaling, and control logic in more complex circuits. The compact 3-pole design helps reduce panel space, and the contactor is compatible with common motor protection schemes, typically used alongside overload relays and appropriate fusing in motor control centers.\u003c\/p\u003e\u003c\/div\u003e","brand":"SIEMENS","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":46268164112618,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8039\/3450\/files\/GTG-STOCK-017.png?v=1788727429","url":"https:\/\/gtghardware.com\/products\/siemens-3tb43-contactor-115v-unmp","provider":"GTG Hardware","version":"1.0","type":"link"}
