surge protector for power supply

The JD150K385H4 series are designed for class I (class B) protection of three-phase AC power supply against lightning over-voltage destruction

MAIN FEATURE:

Three phases AC power supply: 3+1 circuit, fits for TT and TN system;
Especially selective parameter of apparatus fits even more to defend equipment in poor-quality power net-work;
Temperature control to shut-off technology and built-in over-current protection circuit avoid fire accident entirely;
Low residual voltage, well protect customer’s equipment;
Red, Green colors LEDs indicate operating state syllabify and straightly;
Remote alert function makes your control easy;
Small size, expedient installation and simple maintenance;
Rarefied craftwork, Can work permanently on bad circumstance.

INSTALLATION

1. The protection box should install close to the general power distribution cabinet (Chart 1)

2. The connection of the SPD

2.1 The protection box connection way, please check attached instruction. .

2.2 There is alarm transit port on the SPD (normally low impedance, failure high impedance. ) . Connection port is on the plate inside the case. If long distance control needed, just plug the alert device in open circuit. .

2.3 Check all the connections, then electrify, All indicators green shows the lightning protection box normal.

NOTICE

Shut down power supply before installation. The connecting cable must be up to standard.
If system operating current of ‘A’ is more than 100A, ‘B’ (a air breaker or meltable fuse of 63A) is necessary. (chart 3)
When the LED lights are in green it shows the SPD is normal, if they are red, that means the SPD has fault and need to be replaced immediately.
When remote alarm spring, check protection box carefully, the failure part must be replaced immediately.
No special maintenance was needed. Check the connection state, working state and LED once a period.
