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
