Electrical, specialty fuses are designed to protect devices and components from damage due to excessive electrical current. The BK/GLR-1-1/2 is a type of specialty fuse that has a wide range of applications and specific working principle.

The BK/GLR-1-1/2 fuse is typically used in applications that include critical cooling system components, hydraulic systems, instrumentation and control systems, heating and air-conditioning systems, and compressor and motor circuits. It is designed for fast-acting protection and interruption of low-voltage AC/DC systems. This fuse is mainly used in the protection of motors, electrical transformers, transformers, fuses service panels, short-circuit protection systems, and surge arresters.

The BK/GLR-1-1/2 fuse operates on the principle of self-resetting when the overload current reaches the specified operating characteristics. The self-resetting feature of the fuse makes it useful in applications where continuous interruption of the circuit is not desirable. When an excessive current flows through the fuse, it will melt in a designated time, interrupting the transfer of power, and resetting itself after the fault has been cleared.

The BK/GLR-1-1/2 fuse is designed to provide with a single-pole response to short-circuit fault currents. It has a temperature-sensitive element inside, which increases its current-carrying capacity with an increase in ambient temperature. This makes the fuse suitable for environments where the temperature range may vary significantly. The BK/GLR-1-1/2 can be mounted on DIN or Fuse Kettles, making it an easy to install component.

When the ambient temperature of the fuse exceeds a certain limit, the maximum power it can carry is then derated to provide safety from the switching forces of a fault current. This makes the BK/GLR-1-1/2 an excellent choice for applications that require protection from faults at temperatures up to 110C.

The BK/GLR-1-1/2 fuse is available in different voltage ratings ranging from 480 volts to 660 volts. The fuse is also available in two pole and three pole versions to provide additional protection under fault conditions. The fuse is also fully compliant with UL, CSA and IEC standards.

In conclusion, the BK/GLR-1-1/2 fuse is a specialty fuse that has a wide range of applications and is designed to operate on the principle of self-resetting. It offers fast-acting protection against overload and short circuit currents, and is suitable to use in temperature environments up to 110C. Furthermore, the fuse is available in different voltage ratings and can be easily mounted on DIN or Fuse Kettles.
