Description

The SBR399 is a 3-pole, 125A modular switch-disconnector with a red toggle handle, the highest-rated 3-pole device in the SBR range. It is designed for main incomer isolation in large three-phase commercial and industrial installations.
The 125A per pole rating accommodates large three-phase supplies, and the simultaneous 3-pole disconnection provides complete circuit isolation. The red toggle ensures clear identification of the main three-phase isolation point within distribution boards.
Part of Hager’s SBR modular switch range, the SBR399 conforms to IEC 60947-3 and is used as a main isolating device in commercial and industrial three-phase distribution.
