The KSD9700/BK05-BB1D is a metallic-shell, snap-action thermal switch designed for reliable over-temperature protection in electrical appliances and industrial equipment. It operates as a normally closed (NC) switch, opening its contacts at a calibrated 160°C setpoint to interrupt up to 10A at 250V AC/DC loads.

Features

  • Metallic shell construction for robust thermal conduction and durability.
  • Normally Closed (NC) snap-action switch opens at a precise 160°C setpoint.
  • High current rating of 10A at 250V AC/DC for direct load control.
  • Compact design with integrated 7cm lead wires for easy installation.
  • Reliable over-temperature protection for motors, transformers, and heating elements.

Description

The KSD9700/BK05-BB1D is a bimetallic disc-type thermal switch housed in a metallic shell for optimal thermal response. When the ambient temperature reaches its factory-calibrated 160°C trip point, the internal bimetallic element snaps, mechanically opening the normally closed contacts to break the circuit. This action provides a failsafe, non-resettable cut-off to protect sensitive components from thermal damage.

Engineered for direct series connection with the load, this switch is suitable for a wide range of AC and DC applications up to 250V. Its metallic housing ensures rapid heat transfer and consistent trip accuracy, while the compact form factor and pre-attached wires facilitate straightforward mounting in constrained spaces within appliances, power supplies, and industrial control panels.

Key Features

  • Bimetallic snap-action mechanism for precise and reliable temperature response.
  • Metallic shell ensures excellent thermal conductivity and mechanical strength.
  • Normally Closed (NC) contact configuration for failsafe protection.
  • Rated for 10A @ 250V AC/DC, suitable for direct load switching.
  • Factory-set trip temperature of 160°C (±5°C typical tolerance).
  • Compact dimensions with integrated 7cm insulated lead wires.
  • Non-resettable, single-use design for guaranteed safety cut-off.
  • Optimized performance-to-cost ratio for high-volume OEM applications.

Applications

  • Over-temperature protection in AC/DC power supplies and battery chargers.
  • Thermal cut-off safety for electric motors, transformers, and solenoids.
  • Temperature limiting in household appliances like coffee makers, rice cookers, and heaters.
  • Protection of power electronics and industrial control equipment.
  • Safety interlock in lighting ballasts and HVAC system components.

Frequently Asked Questions

Is this thermal switch normally open or normally closed?

This KSD9700/BK05-BB1D switch is configured as Normally Closed (NC). The contacts are closed under normal conditions, allowing current to flow. They open mechanically when the ambient temperature reaches the 160°C setpoint, 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 current of 10 Amperes at a voltage of up to 250 Volts, AC or DC. It is designed to be connected in series with the load it is protecting and can directly interrupt power to motors, heaters, or transformers within these ratings.

Can this thermal switch be reset after it trips?

No, this is a non-resettable, single-use thermal switch. Once the internal bimetallic disc snaps open at 160°C, the switch remains permanently open. It must be replaced to restore circuit functionality, which ensures a guaranteed safety cut-off.

How should I mount and install this temperature switch?

For accurate operation, the metallic shell must be in good thermal contact with the component or area being monitored. Mount it securely using the provided leads or appropriate hardware. Ensure the 7cm lead wires are connected in series with the load, observing correct polarity for DC applications.
