Is it possible to switch the lamp directly with a circuit breaker?
Circuit breakers can be used to distribute power, not frequently start the asynchronous motor, the power lines and motors and other protection, when they have a serious overload or short circuit and undervoltage failure can automatically cut off the circuit, its function is equivalent to the fuse switch
Circuit breaker (English name: circuit-breaker, circuit breaker) is able to close, carry and break the normal circuit under the conditions of the current and can be closed, within the specified time to carry and break the abnormal circuit under the conditions of the current Switchgear.
Yes. Circuit breaker itself is the "switch", but this switch is relatively strong, can switch no-load current, load current, short circuit current, but the working life is shorter than the contactor, the cost is relatively high.
Circuit breaker according to its use is divided into high-voltage circuit breakers and low-voltage circuit breakers, high and low voltage line is more vague, generally more than 3kV called high-voltage electrical appliances.
