The module includes a braking transistor and a gate-driver circuit board, fully assembled and mounted inside a NEMA 1 enclosure for indoor installation, and is intended for use with External Dynamic Braking Resistor Assemblies (RGA) to convert the motor’s kinetic energy into heat through a braking resistor. The RTA4-20 corresponds to the 380–480 VAC family within Baldor’s RTA dynamic braking assemblies, one of several voltage variants that also include 208–230 VAC and 550–600 VAC configurations, enabling compatibility with a broad range of Baldor drives. This model provides a compact, integrated braking solution that lets industrial 3‑phase motors decelerate with a controlled braking profile when commanded by the drive, helping protect mechanical systems and extend drive life. When paired with the matching RGA braking resistor, the assembly forms a complete braking path installed as part of the drive’s dynamic braking circuit, with the enclosure providing straightforward mounting in control panels. \u003c\/p\u003e\u003c\/div\u003e","brand":"Balder","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51660490441006,"sku":null,"price":261.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_2b24e8d9-f195-480f-abc3-66895a2a897e.jpg?v=1769538326","url":"https:\/\/plgautomation.com\/products\/baldor-rta4-20-enclosed-braking-transistor-assembly","provider":"PLG Automation ","version":"1.0","type":"link"}
