ZGG40-460 Modular Power Supply SPD

Product code : 1490069446

The ZGG40-460 Modular Power Supply SPD can be used for protection of L-N and L/N-PE. It is applied in the low voltage AC power distribution system, and connected between AC power supply and system equipment in parallel. It can prevent equipment from the impulse surge and transient overvoltage caused by the outside environment (such as lightning, EMI, etc.) or by the system (such as switching effects of the system, startup or shutoff of the inductance and capacitance load, etc.)

Installation

1 This product can only be installed and maintained by qualified professionals. The installation position cannot be touched by hands. Ensure that it is uncharged and check whether the SPD is all right before installation. If there’s damage or the display window is red, the SPD can not be used any more; if the window is green, the SPD is normal.

2 The SPD should be installed behind the fuse (FU1) of the power supply circuit, with the capacity of the fuse not exceeding 125A gL/gG; otherwise an 80A gL/gG fuse (FU2) should be provided in the surge protection branch circuit.

3 Refer to Fig. 3 for connection, according to the marks on the SPD. The sectional area of the conductor must be more than 4 mm2, as short as possible.

4 Connection of remote signalling alarm: the SPD is provided with remote signalling interfaces (1 and 2 normally closed, and 2 and 3 normally open), applicable for remote centralized monitoring or alarm.

5 After the connection, check if the module is fitted in. If so, 1 and 2 are closed, and 2 and 3 are open; if not, repress the module.

Wiring diagram

The ZGG40-460 Modular Power Supply SPD can be arbitrarily combined, to meet different needs of power system protection.

Usage and Maintenance

1 After failure, the SPD shall be automatically disconnected with the power supply circuit through the internal thermal fuse system, the display window changes to “Red” from “Green”, and remote signalling interfaces 1 and 2 are open and 2 and 3 are closed. When the degradation display window is “Red” or there’s a remote alarm signal, the SPD should be changed immediately.

2 The display window of the SPD must be checked after the lightning storm
