Multicomp Pro Thermal Switch Normally Closed 40°C

Multicomp Pro Thermal Switch is a snap-action thermostat with a set point of 40°C, a Normally Closed (NC) contact and automatic reset. It senses changes in ambient temperature and is designed to activate or deactivate connected heating or cooling systems when the set point is reached.

Overview

Once the temperature drops below the reset threshold of 25°C, the switch automatically returns to its closed state. It is rated for a voltage range of 125V to 250V at a 16A contact rating, which makes it suitable for a range of power control applications.

Key Features

• 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: AgNi/Cu (T2) stationary and movable contacts, brass stationary arm, alloy copper movable arm, and PF (phenolic) case and top cover
• Actuation: Bimetal disc, ceramic actuator pin, and aluminium cap housed within a SUS430 stainless steel flange
