Phoenix Contact PTI 2,5-PE/L/NT inštalačná radová svorka, viacposchodová, Push-in, 3-poschodová, 2,5 mm², sivá

In industrial control panels and distribution boards, electricians need a compact and reliable solution for connecting protective earth, line, and neutral conductors in a single terminal block. The Phoenix Contact PTI 2,5-PE/L/NT installation multi-level terminal block answers this need with a three-level design that integrates PE, L, and NT functions in one housing. Its push-in connection technology allows for fast, tool-free wiring of solid and flexible conductors, significantly reducing installation time. With a nominal cross section of 2.5 mm² and a rated current of 24 A, it is suitable for a wide range of building and machine wiring applications. The grey polyamide housing is halogen-free and flame-retardant to UL 94 V0, ensuring safety in demanding environments.
