This model features a factory-installed 12A39 vent limiter

brittle traps to restore proper drainage

ensuring consistent power flow across multiple poles

Enhanced Durability: Constructed with industrial-grade steel to survive high-temperature cycles and continuous mechanical vibration

Using this on a 120V circuit will result in insufficient secondary voltage (approximately 12V)

Intermatic GMXST-I-120 Timer Els PW 17895 This model features a factory-installedThe Intermatic GMXST I 120 is a heavy duty 24 hour electromechanical timer engineered for light duty commercial and industrial HVACR applications. Operating at 120V AC, this SPDT switch supports a robust 21 amp resistive load and is rated for up to 1 HP at 120 VAC. As a veteran grade mechanical time switch, it features captive trippers with 15 minute minimum switching intervals, allowing for precise cycling of pumps, motors, fans, and refrigeration
