Multicomp Pro Thermal Switch, Normally Closed, 40°C

The Multicomp Pro Thermal Switch is a snap-action thermostat designed for precise temperature regulation. It automatically senses changes in ambient temperature and activates or deactivates connected heating or cooling systems upon reaching its set point of 40°C. This ensures consistent environmental control and system protection.

This model operates as a Normally Closed (NC) switch with an automatic reset function, meaning it will automatically return to its closed state once the temperature drops below the reset threshold of 25°C. It is engineered for reliable performance within a voltage range of 125V to 250V at a robust 16A contact rating, making it suitable for a wide array of power control applications.

Key Features & Specifications

• Set Temperature: 40°C with a tolerance of ±3°C.
• Reset Temperature: 25°C with a tolerance of ±5°C.
• Contact Operation: Normally Closed (NC), automatic reset.
• Contact Rating: 16A at both 125V and 250V.
• Terminal Resistance: Below 50 MΩ at 5V DC/0.25A.
• Insulation Resistance: Above 100 MΩ (between terminals and cap at 500V DC).
• Construction: Features high-quality materials including AgNi/Cu (T2) stationary and movable contacts, a brass stationary arm, an alloy copper movable arm, and a PF (phenolic) case and top cover for durability and electrical insulation.
• Actuation: Utilises a bimetal disc, ceramic actuator pin, and an aluminium cap housed within a SUS430 stainless steel flange for secure mounting.
