Multicomp Pro MP-05EN Thermal Switch NC SPST 55°C

The Multicomp Pro MP-05EN Thermal Switch is a reliable bi-metallic snap-action switch designed for precise temperature control and safety applications. This switch is normally closed (NC), opening its SPST (Single Pole, Single Throw) contacts at a calibrated switching temperature of 55°C, and remains open until it is manually reset, ensuring fail-safe operation in heating and protection circuits.

Featuring durable silver alloy contacts, the switch offers excellent electrical conductivity and longevity. Connection is simplified via 6.3mm x 0.8mm (1/4 inch) quick-connect spade terminals, facilitating easy and secure wiring. The compact, flange-mount housing is engineered for straightforward installation, while the accessible horizontal tab connections allow for convenient manual resetting of the device after it has been triggered.

Key Features & Applications

• Precise Thermal Protection: The bi-metallic snap-action mechanism provides accurate and reliable switching at 55°C, making it ideal for over-temperature protection in appliances, transformers, motors, and power supplies.
• Robust Electrical Rating: With a contact rating of 120V AC at 15A or 240V AC at 10A, this switch is suitable for a wide range of industrial and commercial electrical applications.
• Manual Reset Safety: The latching manual reset function ensures the circuit remains broken until an operator deliberately resets it, confirming the fault condition has been addressed before normal operation resumes.
• Easy Installation: The quick-connect spade terminals and compact, flange-mount design allow for rapid and hassle-free integration into existing control panels or equipment housings.

This thermal switch is an essential component for engineers and technicians seeking a dependable, factory-set temperature cutoff device to enhance the safety and reliability of electrical systems.
