Design and Performance
Space-Saving Double-Level Wiring
Combines two independent connection levels in a single terminal block footprint, doubling wiring density on the DIN rail without expanding the panel’s physical width — ideal for space-constrained railway and industrial control cabinets.
Fast, Tool-Free Push-In Wiring
Push-in connection technology across both levels reduces wiring fatigue and installation time, supporting quick, secure termination of solid or ferruled conductors.
Built-In Test Connection Access
In addition to the standard double-function test shaft, this terminal block provides an additional test connection point, giving technicians flexibility for circuit verification on either level without disturbing wiring.
ATEX-Certified for Hazardous Locations
Rated Ex eb IIC Gb per the II 2 G Ex classification, this terminal block is suitable for Zone 1/21 hazardous area installations when paired with Ex-certified accessories.
Railway-Grade Reliability
Purpose-suited for railway industry applications, with a rated surge voltage of 6 kV and Overvoltage Category III insulation properties supporting robust performance in demanding transit and industrial environments.
