The diode combination clamps coil-generated voltage spikes when the coil is de-energized, limiting back-EMF and protecting downstream electronics, PLC inputs, and contacts from transient overvoltage. With clip-on mounting, the 3RT2936-1ER00 can be installed quickly on the contactor frame without rewiring, and it serves as a dedicated accessory within the 3RT2.3\/3RT2.4 family, helping to keep maintenance simple and replacement fast. Specified for 24 V DC operation, this surge suppressor is documented by Siemens as compatible with the 3RT2.3\/3RT2.4 coil configuration, and it appears in major distributors under the same model number, ensuring consistent part numbers across catalogs. \u003c\/p\u003e\u003c\/div\u003e","brand":"SIEMENS","offers":[{"title":"New","offer_id":46268121972970,"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-3rt2936-1er00-surge-protection-device","provider":"GTG Hardware","version":"1.0","type":"link"}
