Overload Trip Switch

This unit is designed and developed solely for independent household loads with automatic shutdown & restart features using “micro-controller”. This unit should be connected in series with the end loads. Under “normal operating condition”, it allows the electrical current to flow through it without any restriction.

In case of over load condition, the unit senses the current precisely and switches off the load and as a result protects the excess discharge. Once the load is switched off and excess current is removed, it reconnects load automatically again after 3 Minutes, and if the same repeats for 5 times the output gets disabled & re-connects only after the power to the load controller is interrupted.
