This Type 3 arrester for 230 V termination devices can be mounted anywhere, including in installation or distribution boxes and in the wiring spaces of devices or socket strips. Phoenix Contact’s BLOCKTRAB can be mounted on any level surface using fixing clips.
2.5 mm² spring-cage terminal blocks with direct plug-in method offer easy installation with minimum wiring. Two conductors can also be connected to each of the double terminal blocks by means of through-wiring.
Since the protective circuit does not influence the test result, there is no need to disconnect the arrester to conduct insulation tests in the system.
