Working Principle

The working principle of the 0273003.V fuse is based on the melting of a conductive bridge, created by an internal element, when the current exceeds the fuse’s rating. When the set current is exceeded, the heat generated by the element melts the bridge, interrupting the circuit immediately. The melting time-delay is compensated for temperature changes, so the fuse will not be damaged by an accidental thermal shock that would otherwise cause premature melting.

The 0273003.V is manufactured with high-sterling quality standards, and its robust construction ensures high durability over time. It also enhances its overall safety, making it a dependable choice for AC circuit protection.
