Description

The SBN399 is a 3-pole, 125A modular switch-disconnector for DIN rail installation, providing simultaneous three-phase manual isolation at the highest current rating in the SBN 3-pole range. Rated IP20 and conforming to IEC 60947-3, it is designed for use as a main three-phase isolator in commercial and industrial distribution boards.
The simultaneous three-phase disconnection ensures complete isolation of all phases when switching off the supply. The 125A per pole rating accommodates three-phase supplies to large commercial premises or industrial sub-distribution boards.
Part of Hager’s SBN 3-pole modular switch range, the SBN399 integrates into standard DIN rail distribution boards and is used in conjunction with upstream fault protection. Compatible with standard DIN rail accessories.
