BK1/S506-80-R

Fuses are one of the most common components used in the construction and repair of electrical power systems. The BK1/S506-80-R fuse is a time-delay ceramic fuse that offers complete overcurrent protection on both sides of the fuse. It is designed to protect circuits from short-circuits, overloads, and over-temperature conditions.

Application Field

The BK1/S506-80-R fuse is for use in DC circuits up to 80A and AC circuits up to 50A. It is ideal for use in automotive, industrial, and HVAC applications. It can also be used in safety-critical applications such as circuit breakers.

Working Principle

The BK1/S506-80-R works on the principle of a thermal element combined with a current element. The thermal element heats up in the presence of current, causing it to expand. When the current exceeds a certain predetermined value, the thermal element will activate and trip the circuit.

The current element of the BK1/S506-80-R works by measuring the current in the circuit and tripping the circuit when it exceeds the current rating. The current element is designed to be more sensitive than the thermal element, so it will activate even before the thermal element has a chance to react. This ensures that minor overcurrents are identified and prevented before they can cause damage or harm.

The BK1/S506-80-R fuse has been designed to operate reliably and accurately in both AC and DC circuits. It is rated for both maximum current and voltage in accordance with IEC standards and UL requirements. This allows it to be used in a wide range of applications and gives it the capability of handling a variety of different current scenarios.

The BK1/S506-80-R is constructed from a special ceramic material that is both heat- and impact-resistant. It features an integrated drainage chamber that is designed to protect the fuse in the event of an overload or short-circuit. The device is also designed to self-extinguish after the overcurrent condition has been cleared, resetting the fuse and allowing the circuit to continue functioning properly.

The BK1/S506-80-R is a reliable and effective overcurrent protection, making it ideal for use in a variety of applications. In addition to its safety benefits, the BK1/S506-80-R also provides improved current and voltage ratings compared to other time-delay fuses, making it a cost-effective and high-performance protective device.
