800A Earth Leakage Circuit BreakerMCCB Circuit Breaker Performance Heat Resistant


SZM1LE series residual current circuit breaker(hereinafter referred to as circuit breaker) is suitablefor distributing network of AC 50Hz, rated voltage 400V, rated current 800A, to make indirect contactprotection to the human being, also to prevent fireaccident caused by ground fault current due to thedamage of insulation of equipment. In addition, it notonly can be used to distribute electric energy and protect the circuit and power equipment against overload and short circuit, but also can be used to switch the circuit or start the motor infrequently. The sampling operational power supply of leakage protec-tion module of common residual current circuitbreakers is two phases, but this series of circuitbreakers is three phases, and if any one of threephases is lack, this circuit breaker leakage protectionmodule can still work normally. The rated residualoperation current and max breaking time may beadjusted according to practical situations.
Providedthat the phase voltage declines to 50V, the leakageprotection module can still work normally. In addition,this circuit breaker has function of leakage alarm output.

Using condition
Ambient air temperature: the upper limit of ambient air temperature shall not exceed +40℃; The average ambient air temperature for 24h shall not exceed +35℃; The lower limit of ambient air temperature is not less than -5 ° C.
Installation conditions: it should be installed in a place free from shock and vibration and rain and snow. The upper terminal is connected to the power supply side, and the lower terminal is connected to the load side. The inclination between the upper terminal and the vertical plane should not exceed 5°.

External And Installation Size


Our MCCBs provide you unmatched circuit protection in alternative energy, commercial, industrial, mining, and military applications when protecting conductors against overloads and short circuits.
These circuit breakers are applied in panelboards, switchboards, motor control centers, control panels, combination starters, individual enclosures, and bus duct plug-in units.

The breakers according to the rated maximal value to short- circuit breaking ability (Icu), would be classified four kinds types C (basic type), L (typica1 type), M (second high breaking type) and H (high breaking type). The breakers are of the following characteristics: compact size, high breaking ability, short arc-over distance (some of the "0" arc-over distance) and shake proof. They also undergo the tests of nuclear industry conditions (1E grade) and ship conditions, and become the only product using in nuclear industry base among the same products made in the country, further more become the ideal products applied on land or ships.

Matters need attention

Normally, we will provide the most suitable shipment method for you. If the quantity is few, the goods will be sent by express when the payment is clear. Also, we can transport the goods by air or by sea, just according to your demand
