BK/S504-3.15A Fuses are designed for high-current applications in automotive, marine, industrial, and commercial applications. These fuses are designed to provide protection for wiring, circuits, and electrical components from damaging short-circuits and over-currents. The BK/S504-3.15A uses a highly durable ceramic body construction with fast-acting, current-limiting technology. The ceramic body of this fuse has been engineered to provide superior temperature insulation, as well as increased thermal efficiency.This fuse is designed to trip on an overload, limiting the current flow and protecting the circuit from overcurrent damage. The BK/S504-3.15A is UL recognized and CSA certified. In addition, the fuse is rated for currents from 0.25 to 25 amps and provides overcurrent protection from 150 to 500 volts. This device is commonly used in back-up power supplies, fire alarm systems, smoke alarms, and HVAC (heating, ventilation, and air conditioning) systems.The BK/S504-3.15A Fuse has an internal design that contains a pair of wires, which provides a high-break capacity in parallel with the conducting element. The two wires are wound in a continuous loop around the conducting element and are separated by a small arc gap on the circuit. As current begins to flow through the element, the current increases and the arc gap closes. This causes a temperature rise in the wire, which triggers the fuse to trip, opening the fuse.When the fuse is open, the current flow is interrupted and the circuit is protected from further damage. The arc gap on the circuit can be adjusted to provide the desired current rating. The fuse is designed to be used in both AC and DC circuits and is self-resetting, which means it will reset itself whenever the cause of the overcurrent is removed, allowing the circuit to be safely operated again.The BK/S504-3.15A Fuse is a fast-acting, current-limiting device that provides superior protection for a wide variety of circuits and applications. Its ceramic body construction, robust design, and fast-acting response make it a reliable choice for use in a variety of applications. It is UL recognized and CSA certified, providing added assurance of its high quality and reliability. With its adjustable arc gap, the BK/S504-3.15A is able to meet the needs of many different circuit designs and current requirements.
