Over-current Protection Feature

Over-current protection refers to two kinds of protection: line protection and neutral protection (exclude three pole breaker). In case of line over-current protection, current and time are set by the manufacturer conventionally as per user’s demands (user can also set the value themselves); In case of neutral over-current protection, current and time correspond to setting value of line automatically at the ratio of 50% or 100% In (rating of neutral phase), which can be determined by users.

1.Over-load Protection

Inverse long-delay overload protection, setting current Ir1 is adjustable; When this function is “OFF”, circuit won’t be broken off where as alarm will be sent out. Long-delay overload time t_L is adjustable.
