Hager Switch Disconnector 3 Pole 125A SBN399

Hager SBN399: 3 Pole 125A Modular Switch Disconnector for DIN rail mounting in distribution boards.

Safety & Reliability

This Hager switch disconnector gives you a positive, visible off-position across all three poles, so isolation for maintenance or fault-finding is quick and unambiguous. Rated at 125A and 400V AC, it handles the demands of a busy Hager distribution board without derating concerns, and the 1.5kA short-circuit withstand rating means it holds up under fault conditions rather than failing prematurely.

Installation & Space-Saving Design

Built for standard DIN rail fitting, the unit clips straight into your enclosure with no additional brackets or adapters required, cutting installation time on site. At just 3 modular spacings wide, it keeps your panel layout compact, an important consideration when board space is tight and you need to fit multiple Hager Ltd devices alongside protective gear.

Compliance & Distribution Board Ready

As part of the Hager Ltd modular device range, this main switch is designed to integrate directly with Hager distribution board systems, so you get guaranteed compatibility rather than a mix-and-match fit. The IP20 enclosure protects against accidental contact once installed behind a distribution board front, meeting expectations for panels accessible to trained personnel.
