087706.3MXEP

Fuses come in many shapes and sizes, but all of them serve the same purpose. 087706.3MXEP is one of them, and it has its own specific application field and working principle.

Application Field

The 087706.3MXEP is a medium time-lag, Class RK5 dual-element fuse used to protect motors, transformers, and other large electrical Machinery. It is also suited for use as a controller/overload in automatic control systems. The 087706.3MXEP is designed for higher interrupting rating than the Class RK1 fuses and lower melting I2t than the Class RK5 fuses.

Working Principle

The working principle of the 087706.3MXEP is quite simple; it acts as a circuit breaker when the current exceeds a certain limit. The fuse has two elements: a primary element and a secondary element. The primary element is composed of a smooth, resistant conductor and an electromagnet and is designed to trip when the current flow exceeds the desired limit. The secondary element is a wire element that melts when the primary element trips, opening the circuit and protecting against further damage.

In order to ensure that the 087706.3MXEP operates correctly and provides reliable circuit protection, the fuse must be installed in accordance with the related standards. The fuse should also be regularly inspected and tested to ensure that it is operating correctly.

Conclusion

The 087706.3MXEP is a medium time-lag, Class RK5 dual-element fuse used to protect motors, transformers, and other large electrical machinery. Its working principle is quite simple; it trips when the current exceeds the desired limit. In order to ensure that the 087706.3MXEP operates correctly and provides reliable circuit protection, the fuse must be installed in accordance with the related standards and inspected and tested regularly.
