KSD9700/BK05-BB1D Metallic Shell Temperature Control Switch 120C Normally Closed - 5A 250V
The KSD9700/BK05-BB1D is a metallic-shell, snap-action thermal switch designed to open a circuit at a precise 120°C setpoint, protecting appliances, power supplies, and industrial equipment from overheating. It features a normally closed (NC) contact configuration rated for 5A at 250V AC/DC.
Features
- Normally Closed (NC) snap-action thermal switch opens at 120°C (±5°C typical)
- Rated for 5A continuous current at 250V AC/DC for robust circuit protection
- Durable metallic shell construction for effective heat transfer and mechanical durability
- Compact form factor with 7cm lead wires for easy integration into existing wiring
- Reliable, maintenance-free operation for over-temperature protection in enclosed spaces

The KSD9700/BK05-BB1D is a bimetallic disc thermal protector. When the ambient temperature around its metallic shell reaches the calibrated setpoint of 120°C, the internal bimetallic disc snaps, mechanically opening the normally closed electrical contacts to break the circuit. This action provides a fail-safe cutoff to prevent damage to motors, transformers, or heating elements.
Its hermetically sealed metallic housing ensures rapid thermal response and protects the internal mechanism from dust and condensation. The switch is self-holding; it will remain open until the temperature cools sufficiently below the setpoint, at which point it automatically resets, closing the contacts to restore normal operation. This makes it ideal for repetitive protection cycles in consumer appliances and industrial control panels.
