ABB OZ331SPB Round Rotary Handle, Black, 6 mm Shaft, IP65, for OT16-1250 Switch-Disconnectors

Operating an industrial switch-disconnector safely and reliably often requires a handle that can withstand harsh environments while providing clear status indication. The ABB OZ331SPB round rotary handle answers this need with a robust, IP65-rated design that ensures dependable manual control for ABB OT16-1250 series switch-disconnectors. Its black thermoplastic body and 6 mm shaft make it a practical choice for panel builders and maintenance teams who demand both performance and durability.

Who is it for

This handle is intended for electricians, panel builders, and facility maintenance personnel who install or service ABB OT16-1250 switch-disconnectors. It is especially valuable in industrial settings where dust, moisture, or washdown procedures are present, and where a lockable OFF position is required for safety during maintenance. The direct door-mounted operation simplifies integration into enclosures, while the O-I indication provides unambiguous status at a glance.

Tips

When installing the OZ331SPB, ensure the switch-disconnector is in the OFF position before mounting the handle. For added safety, use a padlock with a shackle diameter up to 8 mm to lock the handle in the OFF position. Regularly inspect the handle for signs of wear or damage, especially in environments with high vibration or frequent operation. If the handle is exposed to cleaning agents, verify compatibility with thermoplastic materials to maintain its IP65 sealing integrity.
