Reliable 24VDC Operation: Optimized for standard control circuits with a low-power draw that minimizes coil thermal stress
making it the ideal solution for moving liquids from lower to higher pressures without the maintenance headaches of mechanical seals or motor failures
lead wires are typically detachable and may be reused or replaced separately based on the condition of the insulation
check the nameplate for specific inverter-duty ratings if you intend to use it with a VFD
preventing the low suction pressures that lead to coil icing
Lochinvar & A.O. Smith 100110887 Switch 326010-701 Reliable 24VDC Operation: Optimized forThe Lochinvar & A. O. Smith 100110887 Blocked Outlet Switch is a critical safety component engineered for BTH 400A Series 100 101 gas water heaters and compatible Lochinvar Knight boilers. This normally closed switch is calibrated to a 1. 39 inch water column, providing precise monitoring of the exhaust vent airflow. Designed to detect back pressure or obstructions in the flue, it serves as a fail safe by interrupting the 24V control circuit to the
