YLM30L series RCBO (Hereafter be referred to as the circuit breaker) which is based on four extremely Moulded Case Circuit Breaker applies to circuit exchange 50HZ, Fixed isolation voltage 800V, Fixed working voltage 400V and below, rated current from 10A to 630A circuit. It is used to assign the electrical energy and protect line and the power equipment from overload, the short circuit, owe breakdown voltage damages and so on. At the same time, it can be used in line and electric motor's infrequent analysis and synthesis (transformation). When the line or the electrical machinery breaks down, it can automatically protect and clear the circuit. It is especially good to be used as TN-S three-phase four-wire system's line master switch in residential design.
Because it has used the micro processing technology, its leakage characteristic has the following two characteristics:
1 The fixed surplus working current I△n has 50mA, 100mA, 200mA, 300mA,100mA, 200mA, 300mA, 500mA and 200mA, 300mA, 500mA, 1000mA three ways and four adjustable grades ,in each way four grades of fixed surplus magnitudes of current may be adjusted according to the actual need and the operating time can also be chosen freely. During the adjustment, fixed surplus current I△no which is not working changes according to it.
2 while surplus working current is adjusted, this circuit breaker has also provided two tripping ways: the non-time delay and the time delay. When it is in non-time delay state, tripping time is less than 0.2S, while in time delay state it has two adjustable grades of 0.4S and 0.6S.
The circuit breaker may be installed vertically (i.e. vertical attire) as well as horizontally (i.e. horizontal attire).
The circuit breaker may not but actually be coiled in the opposite way. It has small volume, high short circuit breaking capacity, and short arc over, and vibration resistance.
