Siemens Building Technology 357-0001 Stat 320788-703 This 120V to 24V step-down

This 120V to 24V step-down transformer is typically used for powering heating/cooling control systems

This part is a vital fail-safe that prevents fire hazards and heat exchanger meltdowns should the primary operating control fail

High Environmental Tolerance: Designed for demanding mechanical rooms with a wide operating temperature range for consistent HVAC actuator resistor board performance

Split Construction: The 7JES split sleeve design allows for "in-place" installation

Technicians can utilize the external push-button for manual override and a selectable direction switch to streamline field commissioning and testing

Siemens Building Technology 357-0001 Stat 320788-703 This 120V to 24V step-downThe Siemens 357 0001 TH 357 Limitem is a high performance pneumatic low limit thermostat designed for precision air temperature monitoring in commercial air handling units. This gradual direct acting controller utilizes a liquid filled, 8 foot averaging bulb to sense temperature fluctuations across a duct cross section, providing a proportional pneumatic signal to downstream dampers or valves. With an operating range of 35 to 145 F, it is frequently
