It uses a 120 VAC coil and can switch loads up to 300 VA at 120 VAC on its contact outputs, making it suitable for controlling a burner motor and pilot circuit in older controls. The MC20-1101 is the updated replacement for the MC20-1001, with upgrade options available via the 3420-104 Uni-Kit that includes hardware to swap in the newer unit in compatible systems. Note that the MC20-1101 has been discontinued by the manufacturer and is commonly found through surplus, used, or legacy replacement channels. Typical applications include furnace and boiler controls that require a timed start sequence to ensure safe ignition and operation, particularly in oil burner installations where a fixed 90-second delay helps coordinate valve actuation and ignition timing.\u003c\/p\u003e\u003c\/div\u003e","brand":"Robertshaw","offers":[{"title":"New","offer_id":46284572131562,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8039\/3450\/files\/GTG-STOCK-023.png?v=1788727428","url":"https:\/\/gtghardware.com\/products\/robertshaw-mc20-1101-time-delay-relay","provider":"GTG Hardware","version":"1.0","type":"link"}
