{"product_id":"b-b-422-high-energy-surge-pro-w-tb","title":"B\u0026B 422 HIGH ENERGY SURGE PRO W\/TB","description":"The Model 422HESP is designed to help protect against lightning strikes, power surges, and other types of voltage disturbances. Five RS-422\/485 signals on terminal blocks are supported with a clamping voltage of approximately 6.8 volts. The 422HESP offers three stages of protection starting with a gas discharge tube followed by a series resistor and finally a Transient Voltage Suppresser (TVS). In order for a surge protector to work properly it is important to have a good connection to earth ground. The 422HESP offers two terminal posts and two metal mounting brackets which provide a good ground connection for the user. The 442HESP has been tested to two specifications at 6 kilovolts, IEC 1000-4-5: 1995 \"Surge Immunity Test\" and IEEE C62.41-1991 \"IEEE Recommended Practice on Surge Voltages in Low-Voltage AC Power Circuits\". To ensure the best protection of your equipment some simple connection guidelines should be followed.\n\u003cul\u003e\n\u003cli\u003eHelps you reduce the repair cost for equipment\u003c\/li\u003e\n\u003cli\u003eOffers Terminal Block surge protected outlets\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"B+B SmartWorx","offers":[{"title":"Default Title","offer_id":67663147827385,"sku":"422HESP","price":164.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0274\/4490\/4014\/files\/241943150.jpg?v=1791400837","url":"https:\/\/www.lttpartners.com\/products\/b-b-422-high-energy-surge-pro-w-tb","provider":"LTT Partners","version":"1.0","type":"link"}
