BK/PCH-2-1/2 Application Field and Working Principle

BK/PCH-2-1/2 low voltage miniature fuse,is a non-reloadable fuse produced by Hy-Volt Co., Ltd. It is widely used in communication gear, office equipments, electronic products and instruments as overcurrent protection. This thermal cutoff fuse can work with very small sized fuses equipped with hanger support. The fittings of these fuse are in conformity with DIN standard. The undermentioned features of this product are:

• High interrupting capacity: The high interrupting capacity of these fuses make it suitable for reliable protection of low voltage circuits and equipments.
• Fast acting: The fast acting response of BK/PCH-2-1/2 low voltage miniature fuse make it reliable and efficient for overcurrent protection.
• Special design: The unique design of the fuse makes it able to able to withstand extreme temperature variation and atmospheric pressure.
• High overload limit: These fuse are designed to have a high overload limit so as to safely and quickly identify any overload in the circuit they are protecting.

The working principle of BK/PCH-2-1/2 fuses is that when a circuit overload occurs, increased current flows through the arc of the fuse, which causes it to heat up and expand. This expansion triggers the release of the thermal cutoff strip at the top of the fuse, which then breaks the circuit and cuts off the power. This prevents further damage to the components in the circuit by breaking the circuit before any serious damage is done.

Since these fuses are designed to provide the exact amount of protection required for each type of circuit, it is important to choose the right fuse for the job. If the fuse is rated too low, it may not be able to respond quickly enough to an overload in the circuit. On the other hand, if the rating is too high, it may not trip at all. Therefore, it is important to choose an appropriate rating for the circuit being protected.

In conclusion, BK/PCH-2-1/2 low voltage miniature fuse is one of the best overcurrent protection devices as it is very fast acting in response, features high overload limit, is capable of withstanding extreme temperature variation and atmospheric pressure. It also has a high interrupting capacity and durable design. This fuse is ideal for protecting circuits, equipments and other sensitive components from electrical overloading.
