Multicomp Pro Thermal Switch NC 140°C 10A

The Multicomp Pro Thermal Switch NC 140°C 10A is a normally closed snap-action thermostat switch that senses temperature changes at 140°C. With a contact rating of 10A at 250V, it is designed to regulate the temperature of a system or environment, keeping the circuit closed until the set temperature threshold is reached.

Overview

The switch is intended to manage heating or cooling systems in a variety of settings, including HVAC and industrial equipment. Its automatic reset function returns the switch to its original state once the temperature cools to the reset point of 120°C, so the circuit closes again without any manual adjustment.

Key Features

• Normally closed (N/C) contact operation
• Set temperature of 140°C ±4°C
• Reset temperature of 120°C ±6°C
• Contact rating of 10A at 250V
• Maximum resistance between terminals of 50mΩ at DC5V/0.25A
• Insulation resistance of minimum 100MΩ at DC500V
• Dielectric strength of 1500VAC for 1 minute
• Maximum ambient temperature of 170°C

Construction and Materials

The switch uses AgNi/Cu (T2) stationary and movable contacts, a brass stationary arm and a PF case with a top cover. The bimetal disc is made of a special alloy, and the movable arm is constructed from alloy copper. The terminal is brass with nickel plating.

Certifications

The thermal switch is certified according to GB14536.1-2008, GB14536.10-2008, GB/T22687-2008, EN60730-1 and EN60730-2-9.

Installation

The sensor housing features a flange mount for secure attachment to surfaces, and the sensor terminals are quick connect for straightforward wiring.
