Why Choose the ABB OZ371PB Black Handle with Door Coupling?
The ABB OZ371PB is a black operating handle with door coupling designed for compatible ABB OT switch-disconnectors. It provides an external manual operating interface while incorporating door coupling in the ON position, helping maintain secure enclosure operation in industrial switching and isolation applications.
Designed for ABB OT16–125F and OT30–100F switch-disconnectors, the OZ371PB features a compact 66 × 66 mm format and is intended for use with a compatible 6 mm operating shaft. Its door-coupling mechanism is non-defeatable in the ON position, preventing the enclosure door from being opened while the switch is switched on.
With an IP65 protection rating and NEMA 4X classification, the OZ371PB is suitable for demanding switchboard, control-panel and machinery applications. Its black finish provides a professional appearance while the dedicated ABB design ensures compatibility with the specified OT switch-disconnector range.

Secure Door-Coupled Operation for ABB Switch-Disconnectors
Door-coupled operating handles allow an internally mounted switch-disconnector to be operated from the exterior of its enclosure. The mechanical coupling between the handle, operating shaft and switch provides direct manual control while helping maintain the protective separation between personnel and the electrical switching equipment.
The ABB OZ371PB incorporates a non-defeatable door-coupling arrangement in the ON position. This means the enclosure door cannot be opened through normal operation while the compatible switch-disconnector remains switched on, making the handle particularly useful in machinery, distribution and industrial isolation assemblies.
Typical Applications
- ABB OT16–125F switch-disconnector installations.
- ABB OT30–100F switch-disconnector installations.
- Industrial machinery isolation systems.
- Electrical switchboards and distribution panels.
