Power supply SPD GN-1 series
Showden Co., Ltd.
About This Product
■JIS C 5381-11 compatible Imax10kA class II SPD standard model
The GN-1 series is a standard model of class II SPD with high cost performance that supports a nominal discharge current of 8/20μs 5kA and a maximum discharge current of 8/20μs 10kA. Compatible with the ``nominal discharge current 5kA'' or higher requirement of low-voltage SPD class II in the public construction standard specifications (2019 edition).
■Features
Compatible with low voltage SPD class II of public construction standard specifications (2019 edition)
■Can also be connected to the primary side of an earth leakage breaker
Annex K of JIS C 5381-12:2014 stipulates that in TT systems (including Japanese power distribution systems), when connecting an SPD to the primary side of an earth leakage breaker, a voltage switching element such as a spark gap, GDT, etc. It is described that it is implemented. The GN-1 series can be connected to the primary side of an earth leakage breaker without any problems by installing a GDT (gas-filled discharge tube) between N and E.
■Model names that include specified SPD separators as a set have also been added.
The old standard JIS C 5381-1 did not require safety in the event of an SPD short-circuit failure, so 50AF/50AT MCCBs have been mainly used for SPD separators. On the other hand, the new standard JIS C 5381-11 requires testing for safety in the event of SPD failure in combination with the SPD separator specified by the manufacturer. Therefore, when using an SPD that complies with JIS C 5381-11, it is necessary to connect the specified SPD separator.
This time, we have added a model name that includes a specified SPD separator as a set. This set model name with the SPD separator eliminates mistakes in SPD separator selection and allows safer use.
*SPD can be mounted on a DIN rail and mounting brackets (optional), but fuses can only be mounted on a DIN rail.
