Product Name: Mini Circuit Breaker MCB 6KA Din Rail Miniature Household Air Switch
SFB1-63-series circuit breakers are applicable for places with AC 50Hz or 60Hz, rated voltage of 400V and below, and rated current of 6A-63A. It is mainly used for overload and short-circuit protection of lighting, power distribution lines and equipment in office buildings, residences and similar buildings. It can also be used for infrequent line transfer under normal conditions.
- Functions: Overload, short-circuit protection
Red and green indicator lights, power on and off at a glance, to avoid wrong operation.
1, PA66 (nylon), flame retardant material shell;
2, Material in line with the European ROHS certification standards;
3, Flame retardant grade ; 960 ºC ≤ 15 seconds automatically extinguished (national standard requirements ≤ 30 seconds)
Handle radian conforming to human habit, improving operation comfort, increasing appearance fullness, and making it more convenient and comfortable to use.
