Frequently Asked Questions - JK102SPD HAGER

What is the JK102SPD used for?

The JK102SPD is a Surge Protective Device (SPD) designed to protect electrical installations from transient overvoltages caused by lightning or switching events.

How do I know if the JK102SPD has failed?

The device features a mechanical end-of-life indicator: a green window indicates protection is active, while a red window signals that the SPD has reached its end of life and should be replaced.

What is the maximum discharge current of this SPD?

The maximum discharge current (Imax) is 40 kA (8/20 µs waveform), providing robust protection against severe surges.

Can the JK102SPD be installed on a DIN rail?

Yes, the device is designed for DIN rail mounting (EN 60715) and occupies a single 18 mm module.

What voltage is required for the JK102SPD?

It operates at a rated AC voltage of 230 V (50/60 Hz) with a maximum continuous operating voltage (Uc) of 275 V.

Is the JK102SPD suitable for outdoor use?

No, the enclosure rating is IP20, meaning it is protected only against solid objects larger than 12 mm. It should be installed indoors in a dry location.

How often should the JK102SPD be replaced?

There is no fixed replacement interval. Replace the device when the end-of-life indicator shows red or after a major surge event that could have degraded it.

What is the voltage protection level (Up) of this SPD?

The voltage protection level (Up) is ≤ 1.5 kV, ensuring sensitive equipment is protected from overvoltages.

Can the JK102SPD be used in single-phase systems?

Yes, it is suitable for single-phase systems (L, N, PE) and provides protection in all modes: L-N, L-PE, and N-PE.

What tools are needed for installation?

Installation requires basic electrical tools such as screwdrivers and wire strippers. The device snaps onto the DIN rail and terminals accept up to 16 mm² conductors.

JK102SPD

Product Description

A Surge protection device (SPD) kit specifically developed for Hager standard TPN (Type B) Distribution boards. Developed to ensure optimal performance of SPD technology within Hager distribution boards. SPD is CT2 type to ensure compatibility with all common UK Earthing arrangements e.g. TN-C-S (PME), TN-S and TT earthing arrangements. This is an IEC Type 2 / class II SPD for 3 – phase power supply networks. A type 2 SPD is generally used in sub-distribution boards, downstream of the primary board which may incorporate a Type 1 SPD.

This SPD kit fits within the standard distribution board. Line, Neutral and Earth connections are via copper busbar and copper links, minimising SPD conductor losses, maximising the effective performance of the SPD ( U_p effective). SPD performance coordination with upstream Type 1 SPD within Hager MCCB Panelboards has been verified.
