First, the scope
DZ47LE-125 series leakage circuit breakers ( 125A leakage circuit breaker ) for AC 50Hz or 60Hz, rated voltage 400V, rated current of 125A short circuit and overload protection following lighting distribution system or motor distribution system, product appearance compact, light weight, excellent performance and reliable breaking capacity high, tripping quickly, rail, housing and components of high fire-retardant and impact-resistant plastic, long life, under normal circumstances can be as infrequent conversion of the lines used, it can be installed over undervoltage, shunt release and other accessories, also applies to the isolating switch and a circuit and under voltage protection and remote disconnect purposes.DZ47LE-125 leakage circuit breakers in low voltage distribution systems have increasingly been used as a ground fault and direct contact, indirect contact shock of backup protection. The products are mainly used in building illumination and power distribution systems, in line with GB16917.1 and IEC61009-1 standards. Our company has passed the national CCC, CE certification. & nbsp;
Second, model and specification
Third, the structural characteristics
DZ47LE-125 leakage circuit breaker is assembled by the leakage release from attachment and DZ47-125 miniature circuit breakers, earth leakage circuit breaker current action electronic leakage circuit breakers, mainly by the zero-sequence current transformer, electronic component board, leakage release and circuit breaker with overload and short circuit protection components.Fourth, the main parameters and technical performance
◆ Main specifications:◇ frame degree current: 63A, 80A, 100A, 125A
◇ technology is divided into: Two-wire unipolar, bipolar two-wire, three-pole three-wire, three-pole four-wire.
