SIEMENS 5ST37840 Pin Busbar 16mm², 1x RCD 1P+N + 10x Compact Devices, 12 TE

Pin busbar for efficient power distribution in electrical panels, integrating one 1P+N residual current device (RCD) and ten single-pole modular devices in a compact 12 module unit (TE) footprint. The 16 mm² copper conductor supports rated current up to 63 A, ensuring reliable supply for connected equipment.

Advantages

Streamlines panel wiring by replacing multiple individual connections with a single busbar, reducing installation time and potential wiring errors. The pin connection type provides secure and maintenance-free contacts for Siemens SENTRON modular installation devices.

Suitable for

• Distribution boards requiring combined RCD protection and multiple outgoing circuits
• Residential and commercial electrical installations
• Retrofitting existing panels with Siemens SENTRON components
