Ashcroft 93568 Temperature Switch 75-205F Watertight

Product Description

The ASHCROFT 93568 is a single setpoint temperature switch designed for watertight service across a wide range of industrial and commercial applications. It features a 4-inch rigid stem and a DPDT (double-pole, double-throw) contact form, making it suitable for control and alarm circuits where reliable switching at a fixed temperature setpoint is required. The operating temperature range spans 75 degrees F to 205 degrees F. Certified to UL, CSA, CE, ATEX, IECEx, and RoHS standards, the 93568 is built to meet demanding regulatory requirements across multiple industries. Licensed HVAC technicians, industrial maintenance professionals, and mechanical contractors typically specify and install this switch.

The ASHCROFT 93568 is used across a broad range of industries including boilers and burners, heating and air conditioning systems, hydraulic and lubrication systems, chemical and petrochemical plants, food processing equipment, degreasers and evaporators, marine equipment, offshore oil rigs, power plants, ground support equipment, and pulp and paper operations. Its watertight construction makes it well suited for environments where moisture exposure is a concern during normal operation or maintenance cycles.

Compatibility

Rated for use with boilers and burners, heating and air conditioning systems, hydraulic and lubrication systems, chemical and petrochemical plants, food processing equipment, degreasers and evaporators, marine equipment, offshore oil rigs, power plants, ground support equipment, and pulp and paper installations where a watertight single setpoint temperature switch with a rigid stem is required.

Installation Notes

Installation should be performed by a qualified industrial technician, licensed HVAC mechanic, or licensed mechanical contractor in accordance with applicable local codes and equipment manufacturer guidelines. Shut down and de-energize the system fully before removing or installing the switch, and allow the process fluid or surface to cool to a safe handling temperature. Verify that the selected setpoint and stem length are appropriate for the process pipe or vessel before insertion. Wiring of the DPDT contacts must comply with applicable electrical codes, including NEC Article 430 where motor control circuits are involved.
