We analyzed recent 5 years' fire accidents, and found they were mainly caused by short circuit, overload power consumption and  poor contact.  short circit acount for the largest percentage.

While the traditional breaker open time is millisecond, which is not able to limit short current efficiently. the best method is adopting the fast response time current-limit techonology.



1. overcurrent protection. fast limit current within 150us and alarm
2.overload protection
3.over-temperature protection
4.over/under voltage protection.
5.wire temperature monitoring 
6. leakage monitoring
7.one channel RS485, one channel 2G wireless communication










AAFD series fault arc monitoring device

AAFD fault arc monitoring device monitor circuit fault arc , find the abnormal state and potential safety problems. it is mainly used as a prior protection.

ASCP200 short circuit protector can rapidly cut ff the circuit when fault happened. it is a afterwards protection.

these two series can be used together.
