Application examples

Structure:

This circuit breaker is assembled from DZ47-63 miniature circuit breaker and signal controlled release. The DZ47-63 miniature circuit breaker is mainly composed of an insulation shell, an operating system, a contact system, a thermal magnetic system, and an arc extinguishing system. The signal controlled release consists of a signal input port, a signal voltage detection circuit, a delay control circuit, and a release mechanism. The plastic shell circuit breaker and the signal controlled release are linked through a push rod.

working principle:

When in use, a control voltage is applied to the signal control release of the circuit breaker through the signal input port, that is, the signal voltage (which can be provided by the remote control circuit). Then, the circuit breaker handle is pushed to the closed position, and the operating mechanism drives the moving contact to move towards the stationary contact and make reliable contact with it. At this time, the circuit is connected. When an overload fault occurs in the circuit, the overload current causes the bimetallic element to bend, the overload release to actuate, and the locking mechanism to actuate, thereby achieving the disconnection of the circuit. When a short circuit fault occurs in the circuit, the short-circuit current causes the instantaneous release to operate, pushing the locking mechanism to operate and achieve the breaking function. When it is necessary to immediately cut off the line due to certain needs, the control voltage can be disconnected through the remote control system. At this time, the signal voltage detection circuit receives the signal and outputs a voltage signal to the trip coil, which drives the locking mechanism to operate and achieve the disconnection function. Therefore, this product can achieve the purpose of disconnection in different circuit states.

The circuit breaker is equipped with a shunt release device and has the following characteristics:
The neutral pole is first connected and then disconnected before the overcurrent protection pole is opened and closed;
High rated breaking capacity, up to 6kA;
The operating mechanism of the circuit breaker is a free tripping mechanism with energy storage, which quickly closes the contacts and overcomes the adverse effects caused by manual operation of the handle speed, greatly improving the service life of the product; During normal operation, the contact can only remain in the closed or open position;
The shunt release is composed of driving components such as thyristor and electromagnetic release;
The shell and components are made of high flame retardant, high temperature resistant, and impact resistant plastic.

Wiring: The DZ47S-63 IC card controlled prepaid circuit breaker is suitable for connecting wires of 25mm2 and below. The wiring method is to tighten the wiring with screws and apply a torque of 2.0N · m.
