Siemens Building Technology 540-652A Sensor 320735-701 Durable Construction: Built with silver

Durable Construction: Built with silver cadmium oxide contacts to provide superior conductivity and resistance to arc erosion

Attempting to run this on 115V will lead to torque failure and winding damage

Test for 24V at the coil leads while the thermostat calls for a cycle change

Does the ACT0509 include a conduit connector

Siemens Building Technology 540-652A Sensor 320735-701 Durable Construction: Built with silverUpgrading or maintaining Siemens field panels requires precise sensing hardware. The Siemens 540 652A Room Temperature Sensor is a high performance interactive device designed specifically for Terminal Equipment Controller (TEC) applications. As a veteran in the field, you know that accurate site data is critical; this unit utilizes a highly responsive 10K ohm NTC thermistor to provide stable room temperature monitoring across a range of 55F to 95F
