SCHELINGER A19-BB-1F U-Type Single-Phase Busbar 10mm² 12 Modules 63A

In electrical distribution boards, connecting multiple modular devices such as miniature circuit breakers (MCBs), residual current devices (RCDs), and RCBOs often requires tedious individual wiring, increasing installation time and the risk of errors. The SCHELINGER A19-BB-1F U-type busbar solves this by providing a reliable, space-saving common power supply for up to 12 single-phase modules. With a 10 mm² cross-section and rated current of 63 A, it ensures safe and efficient power distribution in residential and commercial installations.

Who is it for

This busbar is ideal for electricians, panel builders, and maintenance professionals who need a quick and secure method to link multiple DIN rail-mounted devices on a single phase. It is equally suitable for new installations and retrofits in distribution boards, consumer units, and control panels.

Main features

• U-type (fork) design for easy insertion onto device terminals without removing screws.
• Single-phase configuration with 12 modules (pin pitch 18 mm), total length 216 mm.
