The silver cadmium oxide contacts are designed for a 3PST-NO (Triple Pole

By maintaining the V-3000 series actuator with the correct spring rate

and a high-temperature resistant cable assembly to maintain system integrity under constant thermal cycling

Its robust internal diaphragm is built to withstand thousands of cycles while maintaining the strict

a high-performance 4-way reversing valve engineered specifically for technical versatility in heat pump applications

Lochinvar 100170641 Limit Switch 100170641 Refrigerant The silver cadmium oxide contactsThe Lochinvar 100170641 Limit Switch is a critical safety component designed for high performance hydronic systems, serving as the direct OEM replacement for the obsolete TST30010. Engineered with an operating range of 30 210F, this auto reset high limit switch monitors internal water temperatures to prevent catastrophic overheating in Lochinvar Copper Fin II boilers and pool heaters. When temperatures exceed the 210F threshold, the switch opens the
