A fuse is the most basic form of electrical protection device used in electrical systems. The BK/GFA-2-1/2 fuse is one type of electrical fuse which is used to protect the electrical system from overcurrent and, in some cases, short circuit. The BK/GFA-2-1/2 fuse offers added protection against hazardous or damaging electrical conditions.

The BK/GFA-2-1/2 fuse is a dual element branch circuit fuse that is UL listed and CSA certified for 12,000 – 30,000 amperes (A). It is designed for branch circuits in residential and commercial buildings. The BK/GFA-2-1/2 fuse features a 300% minimum overload protection that exceeds the maximum rating of standard branch circuit breakers, which means that it can effectively protect circuits with higher amperage than standard breakers. The BK/GFA-2-1/2 fuse also has a short circuit interrupting rating of 35,000A, which means it is capable of interrupting a higher voltage than standard branch circuit breakers.

The BK/GFA-2-1/2 fuse is made up of two main components: the primary element and the secondary element. The primary element is designed to protect against overcurrent and, in some cases, short circuit. This element is designed to open quickly when the current in the circuit exceeds its rating. The secondary element is designed to provide additional protection against surges. This element is designed to open slowly to lessen the effect of the surge.

The working principle of the BK/GFA-2-1/2 fuse is simple. When the current in the circuit exceeds the maximum rating of the fuse, the primary element will open first. This causes an immediate interruption of the current and protection of the circuit from overcurrent or short circuit. If the primary element fails to open, or if the current in the circuit is too high, the secondary element will then open and provide additional protection against surges.

The BK/GFA-2-1/2 fuse is designed to be used in a variety of applications, including branch circuit protection, industrial control, and motor control circuits. It is also suitable for use in hazardous applications due to its UL listing and CSA certification. The BK/GFA-2-1/2 fuse is a reliable and cost-effective method of protecting sensitive electrical systems from hazardous or damaging conditions.
