{"product_id":"under-over-voltage-relay-phase-failure-phase-sequence-n","title":"3-Phase Under\/Over Voltage Relay with Phase Failure – 400V+N","description":"\u003cp\u003eA compact single-module monitoring relay designed to protect three-phase electrical systems against voltage fluctuations, phase failure, and phase sequence errors on 400V+N supplies. Features adjustable under-voltage (75–95% Vn) and over-voltage (105–125% Vn) thresholds with a time delay range of 0.2–10 seconds, and includes de-energise-after-delay functionality for N-loss detection. Ideal for industrial facilities, motor protection circuits, and control panels where phase stability is critical to equipment longevity.\u003c\/p\u003e","brand":"Daynight Electrical","offers":[{"title":"Default Title","offer_id":44950230859984,"sku":"MVTGBD1N","price":1232.14,"currency_code":"ZAR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0666\/0590\/8176\/files\/MVTGBD1N.webp?v=1772613104","url":"https:\/\/daynightelectrical.co.za\/products\/under-over-voltage-relay-phase-failure-phase-sequence-n","provider":"Daynight Electrical","version":"1.0","type":"link"}
