What is the minimum trip current on a recloser typically rated at?

The minimum trip current on a recloser is typically rated at 2 times the normal load current. This rating is based on the need to effectively trip the circuit during fault conditions. The rationale behind this is that the recloser needs to be able to discern between normal operating currents and those that indicate a fault.

A trip current set at 2 times the normal load current allows the recloser to effectively protect the system by ensuring that transient faults (like momentary overloads or brief short circuits) can be detected and cleared, while still allowing normal operation to continue without unnecessary interruptions.

This balance helps to minimize nuisance tripping while providing adequate protection against overcurrent conditions that could damage equipment or cause system failures.
