KSD9700 250V 5A Metal Thermostatic Temperature Switch NC 60° C

KSD9700 250V 5A Metal Thermostatic Temperature Switch NC 60°C is a temperature-controlled bimetal switch designed to protect electrical appliances and circuits from overheating. Operating in Normally Closed (NC) mode, it opens at 60°C to break the circuit, preventing thermal damage. Its compact metal casing and high reliability make it suitable for motors, transformers, battery packs, and more.

Key Features:

• Automatic reset thermal protection for temperature-sensitive devices
• 60°C cut-off temperature with Normally Closed (NC) operation
• High durability and fast response time
• Metal shell for enhanced thermal conductivity and mechanical strength
• Encapsulated design with electrical insulation
