When the monitored frequency falls to 59.3 Hz, the unit triggers a trip after a fixed 0.120-second time delay, providing a predictable response while avoiding nuisance trips from transient fluctuations. This model belongs to ASCO's 214A line of monitor relays, offering a standalone module intended for integration into control panels and protection schemes where frequency stability is essential. Verified specifications for the 214A-156 include 240 VAC input, trip frequency 59.3 Hz, and a timing delay of 0.120 seconds; these data points are critical for selecting appropriate protection logic and ensuring compatibility with existing ASCO equipment. By delivering a clear underfrequency trip point and defined delay, the 214A-156 helps maintain power system reliability and enables deterministic action in protection schemes.\u003c\/p\u003e\u003c\/div\u003e","brand":"ASCO","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51660232851758,"sku":null,"price":506.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_9a42391d-ea05-4650-989f-1bfc484fa936.jpg?v=1769534913","url":"https:\/\/plgautomation.com\/products\/asco-214a-156-underfrequency-monitor-relay-module","provider":"PLG Automation ","version":"1.0","type":"link"}
