Phoenix Contact’s Blocktrab arresters offer type 3 surge voltage protection for 230 V equipment. This universal arrester has been conceived to be directly fitted into junction boxes or installation sockets, or into connection spaces for multiple socket and equipment outlets. Using the side straps, they can also be fastened to flat surfaces; if the straps are not required, they can be easily removed. Due to their small size, these arresters can also be fitted into 60 mm deep installation sockets situated behind the plug-in 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 as feed-through wiring. Since the insulation is very effective, the arresters need not be disconnected during insulation tests. The Blocktrab arresters comply with all pertinent VDE and IEC standards and are thus suitable for applications anywhere in the world.
