Product Description
KSD9700 Thermostat Bimetallic Thermostat Temperature Controller Thermal Fuse
The KSD9700 temperature protector features a bimetallic design for reliable thermal protection. Composed of a thermal conductive metal casing, bimetallic parts with silver alloy contact points, and heat-resistant components, it automatically disconnects circuits at preset temperatures and resets when cooled.
Principle and Structure
The H20/H21 series universal and enhanced protectors feature large metal casings containing bimetallic components welded with silver alloy contact points, conductive brackets, and insulation stands. During abnormal operation, rising temperatures trigger quick bimetallic action to open contacts and disconnect the circuit. Normal operation resumes automatically when temperatures return to safe levels.
