Weidmuller has extended its line of Surge Protection devices to include a new line of signal, data, and power protection devices.
SPD Series: DIN-Rail Mountable Surge Protection Family
Weidmuller’s SPD II & III series transient voltage surge protectors consist of a range of innovative, compact modules for the protection of low voltage AC/DC distribution systems. Each module is a two-part construction, comprising a TS35 DIN-rail mountable base and a pluggable replaceable arrester, with each single-conductor assembly only 18mm wide. SPD series is listed as UL 1449 edition 4, specifically developed for the US market.
VARITECTOR: For Instrumentation, Control & Automation Circuits
With the VARITECTOR Weidmuller offers a new family of surge protection devices for control and instrumentation (C&I) applications. Long cable runs from the field to the controls need protecting on against electrical surges, caused by remote lightning strikes. These surges can distort signals and damage connected devices. Varitector allows users to ensure their controls and I/O devices are protected from lightning induced surges in cables.
Main Varitector features:
VSPC – Pluggable, replaceable arresters
With the VARITECTOR VSPC, Weidmuller offers protection for up to 4 conductors in one pluggable arrester, plus a dedicated terminal for cable shield connections, which if used provides a path to ground via the Din mounting rail.
Optional remote status signaling is offered by using a Control Unit in conjunction with models with ‘R’ in the descriptor. Each Control Unit can be connected to a group of up to ten VSPC ‘R’s.
VSSC – High density, terminal-type arresters
VSSC4 is the 4-terminal range which provides basic protection functions for single and two conductors, where the cable shield is separately connected to ground.
VSSC6 is the 6-terminal range which includes spare terminals to connect the cable shield and provide a ground path via the Din mounting rail. In most models, options are available for displaying arrester status via an integral LED.
V-Logger 30 – Portable transient logger
V-Logger 30 is a battery powered logger of surge events. Easy to install, and then later move to other locations, with it’s clamp-on sensor, the V-Logger can be used to detect transient surges (>50A) and date/time-stamp them for later analysis.
Typical applications include monitoring ground cables, or a.c. voltage network cabling, to detect the effects of remote lightning strikes or surges due to machinery or switchgear.
