Markel 60048010C Thermostat

The Markel 60048010C Thermostat is a high-performance single pole thermostat specifically engineered for TPI Corporation 3310 Series fan-forced wall heaters. Designed to manage high-wattage industrial and commercial heating loads, this line voltage thermostat features a robust 22A rating at 277VAC, capable of switching up to 4000 Watts. As a dedicated replacement thermostat, it ensures precise temperature regulation in demanding environments where reliable cycling is critical for equipment longevity and occupant comfort. The single pole (SPST) configuration simplifies heater thermostat wiring by breaking one side of the power line, making it a standard choice for technicians performing field maintenance on electric heater parts. Built with heavy-duty internal components, this unit is designed to withstand the rapid thermal cycling common in industrial settings without the contact pitting or degradation found in lighter-duty residential alternatives. Its intuitive mechanical interface prevents complex programming failures, providing consistent set-point accuracy for mission-critical heating systems.

• High Load Capacity: Rated for up to 4000W at 277V, making it ideal for high-output 3310 series industrial heaters.
• OEM Compatibility: Exact fit for TPI, Markel, and Raywall 3310 series models, eliminating the need for field modifications.
• Heavy-Duty Switching: 22A capacity ensures the internal contacts can handle the high inductive and resistive loads of fan-forced units.
• Simplified Installation: Single pole design allows for straightforward integration into existing control circuits.

Can this thermostat be used with other heater brands?
While functionally similar to many line-voltage controls, this unit is specifically dimensioned and rated for the TPI/Markel 3310 series. Always verify the amperage draw and physical mounting footprint before attempting installation on non-specified equipment.

Does a single pole thermostat provide a true off position?
A single pole thermostat breaks one side of the line. While it stops the heater from running at the low set point, it does not disconnect all power to the unit like a double pole (DPST) model. Always use the circuit breaker to disconnect power before servicing.

What is the maximum wattage this unit can control?
The 60048010C is rated for 22 Amps. For a 240V circuit, this supports up to 5280W; however, it is standardly utilized for 3310 series heaters up to 4000W to maintain a safety margin for industrial duty cycles.
