FAQs

What is load breaking switch?

A load break switch is a disconnect switch that has been designed to provide making or breaking of specified currents. ... These switches are used to de-energize or energize a circuit that possesses some limited amount of magnetic or capacitive current, such as transformer exciting current or line charging currents.

How much current can a load break switch interrupt?

In North American practice, approved general-purpose low-voltage fuses must interrupt at least 10,000 amperes. Types used in commercial and industrial low-voltage distribution systems are rated to safely interrupt 200,000 amperes.

What is the advantage of a load break switch?

Load break switch with vacuum circuit breaker is more reliable option. Load break switch with spring mechanism are generally provided with Fuse protection. And hence, every time a fault occurs, fuse needs to be replaced.

Can load break switches be opened while energized?

They should not be operated while the circuit in which they are connected is energized, but only after the circuit is deenergized. As a further precaution, they may be opened by means of an insulated stick that helps the operator keep a distance from the switch.

What does a load break do?

A load break switch is designed to switch the power “on or off” or change the position when the transformer is energized (meaning it has a load on it) and the switch will break it. ... The 2 Position Switch is exactly what it sounds like: on or off.
