Universal Equipment Protection in Miniformat

Phoenix Contact Blocktrab arrestors offer type 3 surge-voltage protection for 230 V equipment.

This universal arrestor has been designed to be directly fitted into junction boxes or behind 13amp sockets mounted in extra deep boxes, or into connection spaces for multiple socket and equipment outlets. Using the side fixing lugs, they can also be fastened to flat surfaces. If the lugs are not required, they can be easily removed. Due to their small size, these arrestors can also be fitted into portable equipment, cash point machines or other appliances that can be damaged by even low level surges, they also lend themselves for fitment into cable trunking and within medical devices in hospital applications.

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. The Blocktrab also has audible indication of failure and so aids swift replacement.

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 applications anywhere in the world.
