Siemens 5ST2504 Power Distribution Block

Siemens 5ST2504 Power Distribution Block is a DIN-rail mounted, single-pole distribution block that channels a single main feed to eight separate circuits in compact control panels. This 5ST2504 model is rated for 80 A and supports feeder voltages up to 690 V, making it suitable for European 230/400 V systems and similar environments. The unit accepts a single input conductor sized up to 16 mm2 and fans out to eight individual output terminals each sized for 10 mm2 conductors, enabling neat, organized branching without compromising conductor sizing. Designed for industrial control panel assemblies, the block provides a clear, low-profile solution for distributing main power to auxiliary components, PLCs, sensors, relays, and other peripherals while maintaining safe separation and simple termination. It is part of Siemens' DIN-rail mounted low-voltage distribution lineup and is well-suited for use in machine automation where a compact footprint and reliable connections are required. Installation typically involves snapping the 5ST2504 onto a standard DIN rail and wiring the incoming feeder into the 16 mm2 terminal, then landing the eight outgoing feeds onto the 10 mm2 terminals, with proper torque and insulation per local electrical codes.
