Lochinvar & A.O. Smith 100111057 Switch 326058-757 As a permanent split capacitorThe Lochinvar & A. O. Smith 100111057 Blocked Inlet Switch is a critical safety component designed for high efficiency commercial water heaters and boilers, including the Cyclone Xi BTH and Shield series. This normally closed (NC) pressure switch monitors the combustion air intake, ensuring the blower assembly receives adequate airflow for safe operation. Engineered with a dedicated 0. 85" W. C. trip point, it immediately breaks the safety circuit if
