Overview
The Siemens 5ST3623 Pin Busbar is a high-quality, pre-assembled solution designed to streamline the wiring of modular devices such as miniature circuit breakers (MCBs) and residual current circuit breakers (RCCBs) within distribution boards. Featuring a robust 10 mm² cross-section, this busbar ensures a safe and reliable power connection. Its unique 2×3-pole configuration (1-phase + Neutral) is specifically engineered for efficient, professional installation across two parallel lines of three modules each. Crucially, the busbar is touch-safe, offering enhanced protection against accidental contact with live parts.

Technical Function
This pin busbar is engineered to distribute power across six total connection points (3 points on each of the two rows). It simplifies the connection of:
-
Up to six single-pole devices (e.g., three MCBs in Row 1 and three in Row 2).
-
Or a combination of three two-pole devices (e.g., three RCDs or two-pole MCBs).
It is intended for use with modular installation devices that feature pin-type terminals.
