Hydrolevel 45-501 24 Volt Low Water Cut-Off for Gas

The Hydrolevel 45-501 (Safgard 500SV) is a 24 VAC probe-type low water cut-off with manual reset for hot water boilers. It cuts burner power right away on low water and locks out the burner circuit if the water stays below the probe for 30 seconds. It can also serve as a secondary low water cut-off on steam boilers.

Key features

• Manual reset that does not trip on power failure
• Test button checks the burner circuit and lock-out without draining the boiler
• LED indicator lights
• Shorter EL 1214-SV probe that fits a standard black tee
• Meets ASME CSD-1 requirements for commercial water boilers
