Phoenix Contact: Lightning Current Protection for 4-Conductor Systems

July 19, 2021

With the TERMITRAB complete product family from Phoenix Contact, they provide you with the narrowest surge protection for measurement and control technology.

With immediate effect, the TTC-6P-4… protective devices for 4-conductor applications can also be used for applications that require test class D1.

This applies both for product variants with Push-in connection technology and for products with screw connection. Your advantage: use TTC-6P-4… at building transitions. Curve-shaped lightning pulses (10/350) µs can be expected here. The components installed in the protective circuit pass the tests of min. 500 A discharge surge current, which is required for test class D1. Alongside the advantage of a very narrow overall width (only 6 mm for a 4-conductor device), you now get higher-performance protection for your applications.
