It stands for Counter-Clockwise Shaft End

Excessive heat during the sweat connection process can damage internal seals and the diaphragm

low-resistance connections for both solid and stranded copper conductors

effectively dissipating heat from the inverter heat sinks during high-torque operations

allowing it to operate in water temperatures up to 160°F

Siemens DDC PTM6.1PSI20-M-R Module THPU32HP7Y It stands for Counter-Clockwise ShaftThe Siemens DDC PTM6. 1PSI20 M R is a core direct drive control component designed for integrating high precision actuator feedback within legacy and modern Siemens building automation systems. As a Positioning Module Refurbished unit, it provides the bridge between the central DDC processor and field level electric motors, facilitating exact movement for HVAC damper control and water flow valves. This specific PTM module utilizes 20 feedback signals
