Why Choose the nVent HOFFMAN MSBS41422 Plug-in Busbar?
The nVent HOFFMAN MSBS41422 is a high-capacity vertical plug-in busbar designed to build reliable power distribution systems within compatible nVent HOFFMAN floor-standing enclosures. As part of the nVent HOFFMAN MSBS plug-in busbar series, it provides an efficient solution for distributing electrical power through industrial switchgear, controlgear and power distribution assemblies.
The MSBS41422 is designed for vertical installation in compatible MSVH busbar supports, where the busbars are secured using standard bolts, washers and nuts. The plug-in busbar system provides a flexible and straightforward installation method and has been tested in accordance with IEC 61439, supporting dependable integration into low-voltage switchgear and controlgear assemblies.
Designed for 2200 mm high enclosures, the MSBS41422 has a busbar length of 1972 mm and supports a rated current of up to 1400 A with a rated short-time withstand current of up to 50 kA. The rated current can be increased to as much as 2 × 1400 A when the incoming connection is positioned in the middle. Manufactured from tin-plated aluminium, the MSBS41422 is supplied as a set of four busbars.
