Product Details
Safgard™ 550 Series Low Water Cut-Off with Manual Reset features a short probe design and operates at 120V to interrupt power immediately in a low water condition. The burner circuit locks out if water remains below the probe for 30 seconds. The manual reset function ensures that it will not trip due to power failures, and a test button allows users to check the burner circuit for proper control operation and lock-out function without lowering the water level. This device is also suitable for use as a secondary cut-off on steam boilers and is made in the USA.
