Siemens 5ST3632 SENTRON barra collettrice a pettine 3 poli 63A 12 moduli

The Siemens 5ST3632 pin busbar stands out from generic distribution blocks by delivering a factory‑insulated, plug‑in solution that eliminates the need for cutting, stripping, and ferruling individual jumpers. Its 18 mm pitch aligns perfectly with standard modular devices, turning a row of MCBs or RCDs into a neat, low‑resistance power rail in seconds.

Highlights

• 3‑pole pin‑type busbar for fast, tool‑free connection of modular protection devices
• Rated for 63 A continuous current and up to 400 V AC, suitable for residential and light commercial distribution boards
• 12 module (TE) length covers a full row of 1‑pole devices or four 3‑pole breakers
• 10 mm² copper conductors with grey insulation for clear phase identification and safe handling
• Compliant with IEC 60947‑7‑1, ensuring dimensional and performance compatibility across SENTRON accessories

In daily use

Installers appreciate how the 5ST3632 turns a potentially messy wiring task into a repeatable, error‑free process. The pin contacts press firmly into the cage terminals of compatible devices, maintaining a secure, vibration‑resistant connection without the need for torque checks on each jumper. Because the busbar is fully insulated, the risk of accidental shorts during maintenance is significantly reduced, and the grey colour coding helps identify the neutral or phase grouping at a glance.
