{"title":"Undervoltage Release Coils","description":"\u003cp\u003eAn under voltage release is an optional device that is installed in circuit breakers. It triggers a power trip if the power drops below a predetermined level. Usually, it's between 70 and 35 percent of the UV rating. It is not powered by the circuit breaker, instead It receives power from an alternative source such as a battery. Although originally designed for coal mines, it can be used in any domain operating in heavy industry.\u003c\/p\u003e\u003cp\u003eAn under voltage release device is composed of a solenoid magnet with a moving arm fixed to a spring loaded latch. This latch holds a spring-biased plunger, which, when released, contacts the trip bar to trip the breaker.\u003c\/p\u003e\u003cp\u003eThe magnetic force can overcome the spring force as long as the voltage to the solenoid magnet is normal. This will prevent the trip bar's release. The magnetic force is overcome if the voltage drops below the preset level or cuts off. This force releases the plunger and then trips the power.\u003c\/p\u003e","products":[{"product_id":"nls-018-g1-8inch-stainless-steel-needle-valve-ptfe-300-bar","title":"G1\/8'' Stainless steel Needle Valve PTFE 300 bar - NLS","description":"\u003cp\u003eVery compact stainless steel needle valve with G 1\/8\" threads. This valve can be used as a reliable shut-off valve, or to accurately control (relative low) flow rates of clean gases or fluids. The valve has a nominal internal diameter of 2.5 mm. The seals are made of PTFE. The max pressure is 300 bar and the allowable temperature range is from -20 to max. 200°C. Thanks to the high quality materials and robust construction, the valve is suited for high pressures and agressive fluids.\u003c\/p\u003e","brand":"Tameson","offers":[{"title":"Default Title","offer_id":46756659003721,"sku":"NLS-018","price":28.82,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0572\/1787\/6152\/files\/nls-012-1.414381c2_ca236438-60ca-4a0b-a29e-1804e5e2820f.jpg?v=1727935996"}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0572\/1787\/6152\/collections\/undervoltage.483f7057_eb0f8f74-dc4c-4636-a780-7fb898096bf2.jpg?v=1774544912","url":"https:\/\/tamisoon.com\/collections\/undervoltage-release-coils.oembed","provider":"tamisoon.com","version":"1.0","type":"link"}
