57.801.5153.0 is a duo feed-through terminal block designed for secure electrical connections in industrial control and distribution applications. It features a rated cross-section of 2.5 mm² with support for fine stranded wire (0.13–2.5 mm²) and solid wire (0.5–4 mm²), accommodating wire gauges from No. 22–12 AWG. The block operates at a rated voltage of 800 V with an impulse voltage rating of 8 kV and a three-phase voltage of 3 kV, with a maximum current rating of 24 A. The terminal block has a 5 mm pitch spacing and an 11 mm width, and is mounted on standard DIN rail (35 mm TS 35) with approvals including SEV-EEX, LCIE BV, and RINA LR certifications. This duo configuration allows for parallel connection of multiple modules, making it ideal for compact panel layouts and space-saving interconnect solutions in electrical distribution systems.
