Generic KSD9700/BK05-BB1D 5A 250V Metallic Shell Temperature Control Switch (60C Normally Closed)
The KSD9700/BK05-BB1D is a metallic-shell, snap-action thermal switch rated for 5A at 250V AC/DC, featuring a normally closed (NC) contact that opens at a fixed 60°C setpoint. This compact, durable protector is designed for integration into electrical appliances, power supplies, and industrial control panels to provide reliable over-temperature cutoff.
Features
- Fixed 60°C (140°F) normally closed (NC) snap-action bimetallic switch.
- Rated for 5A resistive load at 250V AC/DC for reliable circuit interruption.
- Rugged metallic housing ensures mechanical durability and good thermal conductivity.
- Compact dimensions (approx. 9 x 7 x 1 cm) for easy integration into tight spaces.
- Pre-wired with 7cm lead wires for simplified installation and connection.

The KSD9700/BK05-BB1D is a bimetallic disc-type thermal protector housed in a robust metallic shell. Its operating principle relies on the differential thermal expansion of a bimetallic element, which snaps to physically open the electrical contacts once the calibrated temperature threshold (60°C) is reached, thereby breaking the circuit to prevent overheating. The switch remains open until the temperature cools below the reset point, typically a few degrees lower than the trip point.
Designed for direct mounting on heat sinks, motor housings, or within transformer enclosures, its metal casing ensures fast thermal response and long-term reliability in demanding environments. The normally closed configuration makes it ideal for series connection in a power line, where an over-temperature event will safely de-energize the protected device or subsystem.
