YIFA residual current protection circuit breaker manufacture leakage YFM1LE series
Inquire NowDescription
The YFM1LE series leakage circuit breaker represents a state-of-the-art solution for electrical protection, crafted using international advanced design and manufacturing technology. With an insulation voltage of 800V, this circuit breaker is designed for AC50Hz circuits, accommodating a rated working voltage of 400V and a rated working current of 400A. It is ideal for switching circuits and infrequent motor starts.
This innovative circuit breaker features overload, short-circuit, and under-voltage protection devices, ensuring comprehensive protection for both the electrical lines and connected power equipment. It also provides indirect contact protection for individuals, thereby mitigating fire risks associated with undetected earth faults that may evade traditional over-current protection devices. The series is divided into two types based on their rated ultimate short-circuit breaking capacity: L type (higher breaking type) and M type (high breaking type).
The YFM1LE circuit breakers are compact, highly efficient, and vibration-proof. They offer flexible installation options, allowing for both vertical and horizontal setups. They adhere to the standards set forth in GB14048.2 and IEC60947-2.
