Surge Protective Device 20ka-40ka Power AC Surge Protection Protection module for DEHNguard UL series Varistor-Based Protection Module

Type 2 Surge Arresters

The product family is applicable for all common electrical power systems. The Surge Protective Devices (SPDs) are UL 1449 4rd Ed. Approved with a 200 kA SCCR rating and do not need any additional overcurrent protection.

Specification

1. New technology "Advanced Circuit Interruption" (ACI) integrated in the protection module, consists of a switch / spark gap combination.

2. Due to ACI technology no external backup fuse required.

3. Zero leakage current due to galvanic isolation by ACI switch unit.

4. Energy coordination with other arresters of the Red/Line product family.

5. Vibration and shock-tested according to EN 60068-2.

1) All live conductors should be wired so that they are inherently short-circuit and earth fault proof.

Product Description

1. Plug in/out style surge protecive device.

2. The coler of visible window shows operating status.

3. Double protection of over-heat and over-current.

4. Have the accessory of remotes signaling interface,could be remote remote control.

Installation instructions

1. Before installing. you must cut off the power supply. don't operate in the charged state.

2. We suggest a fuse or automatic circuit breaker should be connected in series before the lightningproof module.

3. In installing, Please connect with the installation diagram, as shown in diagram,"+"represents the anode wire,"-" Pepresents the cathode wire, PE represents the earthing wire, the wrong connection is unallowable. After the installtion is finished, turn on the swich of automatic circuit breaker(or fuse), to check whether the working state is normal ot not.

4. After the installation is completed, insert the module properly, and check whether the lightningproof module works normally or not.

5. In the period or using the lightningproof module, inspect, test and view the fault display window state regularly, when the fault display window is red or the remote-signalling terminal outputs the alarm signal, this means the lightningproof module has the fault, you shall repair or change it in time.

6. The parallel power lightningproof module shall be installed in parallel, the wire shall be short, thick and straight, connected firmly and reliably.
