Blocktrab arrestors offer type 3 surge voltage protection for 230 V rated equipment. This universal arrestor has been designed to be directly fitted into junction boxes, installation sockets or into connection spaces for multiple socket and equipment outlets. Using the side straps, they can be fastened to flat surfaces; if the straps are not required they can be easily removed. Due to their small size these arrestors can also be fitted into 60 mm deep installation housings behind the plug sockets.
With direct plug technology the spring-cage terminals offer simple installation and a minimum amount of cabling for wire cross-sections of 2,5 mm². Two wires can be connected to the double terminals in a feed-through configuration.
Since the insulation is very effective the arrestors need not be disconnected during insulation tests. The Blocktrab arrestors comply with all pertinent VDE and IEC standards and are thus suitable for industrial applications.
