Suitable for three-phase four-wire neutral point directly grounded (TT) of the low-voltage grid system, used for the line or electrical equipment ground fault, overcurrent, short-circuit, over-voltage, under-voltage, power outage automatic tripping and phase failure, etc. for protection, but also to provide indirect contact protection for the risk of personal electric shock.
Kini anti-impact, wear-resistant ug walay kadaot sa kabhang ug pagkalawos.
With multiple protections for overload, short-circuit, over/under-voltage, phase loss and leakage.
For ground faults, with sensitive leakage detection, auto-reclosing and multiple protections.
Applicable to construction sites, workshops and old communities for electrical safety.
