Surge suppression accessories like this module protect sensitive control circuits and extend the service life of switching components in industrial and commercial control panels. The module mounts directly onto compatible SIEMENS 3RT-series contactors, keeping the installation compact and eliminating the need for separate suppression wiring. At 0.293 pounds, it is a lightweight add-on suited for panel builders and controls technicians working in tight enclosure spaces.\u003c\/p\u003e\u003cp\u003eThis suppressor module is intended for use in AC control circuit applications where coil-generated transient voltages must be clamped before they reach PLCs, sensors, or other low-voltage control devices. It is a standard accessory in commercial HVAC control panels, motor control centers, and industrial automation panels where SIEMENS 3RT-series contactors are already installed. Electricians and controls technicians typically install this module during new panel builds or as a retrofit on existing contactor assemblies.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSuppresses AC coil voltage transients to protect downstream control components\u003c\/li\u003e\n\u003cli\u003eSnap-on mounting fits directly to compatible SIEMENS 3RT-series contactors\u003c\/li\u003e\n\u003cli\u003eCompact form factor at 2.638 inches x 1.693 inches x 4.646 inches\u003c\/li\u003e\n\u003cli\u003eLightweight at 0.293 pounds for easy handling in confined panel spaces\u003c\/li\u003e\n\u003cli\u003eReduces electromagnetic interference on shared control wiring\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style suppressor accessory for use with compatible SIEMENS 3RT-series AC contactors and relay assemblies.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified electrician in accordance with NEC guidelines and the panel manufacturer's documentation. De-energize and lock out the control panel before installing or removing the suppressor module. The module snaps onto the contactor body without additional tools in most applications. Verify that the suppressor voltage rating matches the coil voltage of the contactor before powering the circuit.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoil Type\u003c\/strong\u003e: AC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 2.638 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1.693 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 4.646 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.293 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePack Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 75455441468\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SIEMENS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 3RT1935-5AM21\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SIEMENS","offers":[{"title":"Default Title","offer_id":51383336337714,"sku":"3RT1935-5AM21","price":158.66,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312678912.jpg?v=1782593684","url":"https:\/\/voomisupply.com\/products\/siemens-3rt1935-5am21-ac-suppressor-module","provider":"Voomi Supply","version":"1.0","type":"link"}
