Fuseholders are used in electrical systems to not only protect electrical components from overloads or short-circuits, but also to protect personnel against electric shock. BK/HMF fuseholders are suitable for medium-voltage, high-voltage and low-voltage fuses. They are versatile, reliable and highly durable.

Definition

BK/HMF fuseholders are designed to utilize type-BK or type-HMF cartridge fuses. Type-BK cartridge fuses are cylindrical and manufactured with a top safety cap. Type-HMF cartridge fuses are manufactured with a cover and sufficient free space to house a supplementary safety fuse, known as a power fuse.

Application Field

BK/HMF fuseholders are frequently used in various low-voltage electrical applications. The applications of BK/HMF fuseholders include medium-voltage motor control, medium-voltage power circuit, medium-voltage power system, low-voltage consumer units, high-voltage motor control and high-voltage power circuit.

The BK/HMF fuseholders can be used in a variety of residential, commercial and industrial applications. They can be employed to protect motors, transformers, distributors, security systems, rectifiers, switchgear, contactors, LEDs and capacitors.

Working Principle

In the BK/HMF fuseholders, breaking of a fuse throws the mechanically operated blades apart to open a circuit. This prevents any further current flow to the circuit. The fuses used in the BK/HMF fuseholders have an integrated over-current protection device. This device quickly detects any rise in voltage or current and interrupts the circuit to protect the load.

The BK/HMF fuseholder provides an easy-to-repair solution by enabling the replacement of the fuse without disengaging the holder. It is also very reliable and durable, able to withstand external temperatures ranging from -25°C to +90°C.

Conclusion

BK/HMF fuseholders are widely used to protect electrical components from overloads and short-circuits in a variety of residential, commercial and industrial applications. It quickly detects changes in voltage or current and interrupts the circuit to protect the load. It provides an easy-to-repair solution as it enables the replacement of the fuse without disengaging the holder. It is versatile, reliable and highly durable, able to withstand external temperatures ranging from –25°C to +90°C.
