Description

The KSD9700/BK05-BB1D is a bimetallic thermal cut-off switch housed in a metallic shell for efficient heat transfer and mechanical protection. Its internal snap-action mechanism provides a Sharp Microelectronics, reliable break in the electrical circuit once the preset temperature of 95°C is reached, effectively preventing thermal damage to connected components.

Designed for direct series connection within a circuit, this switch operates passively without requiring an external power supply. The metallic housing ensures a fast thermal response and is suitable for applications where the switch body can be mounted directly to a heat source. The 7cm insulated lead wires facilitate straightforward wiring into control panels, motor windings, or transformer enclosures.

Key Features

  • Metallic shell for excellent thermal conductivity and physical robustness.
  • Precision-calibrated bimetallic snap-action disc ensures accurate trip temperature.
  • High-current capacity: handles up to 5A at 250V AC/DC for broad application use.
  • Normally Open (NO) configuration: circuit is open at high temperature, providing fail-safe protection.
  • Compact and lightweight design allows for installation in space-constrained environments.
  • Pre-attached 7cm insulated wires simplify electrical connection and integration.
  • Designed for reliable, maintenance-free operation over an extended service life.

Applications

  • Over-temperature protection in power supplies, battery chargers, and transformers.
  • Thermal safety cutoff for electric motors, solenoids, and heating elements.
  • Integration into household appliances like coffee makers, rice cookers, and hair dryers.
  • Protection circuits for LED drivers, audio amplifiers, and other power electronics.
  • Industrial control panel and enclosure temperature monitoring and safety interlocking.

Frequently Asked Questions

What is the trip temperature and contact configuration of this thermal switch?

This KSD9700/BK05-BB1D switch has a Normally Open (NO) contact configuration. The contacts are open when the ambient temperature reaches its calibrated set point of 95°C, breaking the circuit to provide over-temperature protection.

What is the maximum electrical load this switch can handle?

The switch is rated for a maximum continuous current of 5 Amps at a voltage of up to 250 Volts, either AC or DC. It is designed to be connected in series with the load you wish to protect from overheating.

How should I install and use this metallic shell temperature switch?

For optimal performance, mount the metallic shell of the switch directly onto or in close thermal contact with the component or surface you need to monitor. Connect the two pre-attached lead wires in series with the power line of the device being protected. The switch operates passively and requires no external power.

Is this a resettable or one-time-use thermal fuse?

This is a resettable, snap-action bimetallic switch. Once it trips open at 95°C, it will automatically reset and close the circuit again when the temperature cools down sufficiently below the trip point, allowing for repeated use.
