The ABB OS100TPN-A is a 100 A three-pole plus neutral enclosed switch fuse designed for industrial electrical distribution, isolation and fused protection. It combines ABB OS switch-fuse technology with a robust steel enclosure, providing a complete solution for circuits requiring three-phase switching together with a neutral connection.
The OS100TPN-A is housed in a powder-coated RAL 7035 steel enclosure providing IP65 protection. The enclosure measures 400 × 300 × 150 mm (H × W × D) and incorporates removable gland plates, a hinged door with lock and a padlockable pistol-grip operating handle for practical industrial installation and secure isolation.
Rated at 100 A, the OS100TPN-A uses A2/A3 fuse types and provides an AC-23 operational power rating of 55 kW at 400 V. The three-pole switching arrangement is complemented by a detachable neutral link, while incoming terminal shrouds are supplied to provide additional protection around the incoming connections.
A three-pole plus neutral enclosed switch fuse provides switching and fused protection for three-phase circuits while retaining a dedicated neutral connection. Appropriately selected fuses provide protection against overload and short-circuit conditions, while the switch-fuse mechanism provides a clearly defined means of local circuit isolation.
The ABB OS100TPN-A combines 100 A switching, a detachable neutral link and A2/A3 fuse compatibility within an IP65 steel enclosure. Its 55 kW AC-23 rating at 400 V makes it suitable for appropriate industrial motor, machinery and distribution applications where three-phase and neutral connectivity is required.
