Multicomp Pro T23 Series Thermal Switch, Normally Open, 90°C

The Multicomp Pro T23 Series Thermal Switch is a precision electromechanical safety device engineered for reliable temperature sensing and control. Featuring a SPST-NO (Single-Pole, Single-Throw, Normally Open) contact configuration, this switch is designed to activate at a precise switching temperature of 90°C, ensuring your equipment or system operates within safe thermal limits. Upon cooling, the device resets automatically at 50°C, ready to monitor the next cycle.

The construction is robust and tailored for longevity. It incorporates an aluminium sensing cap for rapid and accurate thermal response, paired with a ceramic actuating pin for mechanical stability and electrical insulation. Mounting is secure via a steel nickel-plated bracket, and electrical connection is simplified with brass tin-plated quick-connect terminals. This combination of materials ensures excellent performance and durability in demanding environments.

With a high contact rating of 250VAC/16A (240VAC/15A), this switch can handle significant electrical loads, making it suitable for a wide array of industrial and commercial applications. It also features a high minimum insulation resistance of 50MΩ at 500VDC, providing a critical safety margin and preventing leakage currents.

Compact and designed for flange mounting, it offers easy installation in constrained spaces. Its primary role is in sensing and instrumentation circuits where precise temperature-based switching is required to protect machinery, control processes, or activate alarms. This thermal switch delivers dependable, repeatable performance where it matters most.
