Abb ohy65l10b Pistol Handle Rotary Operator 65mm

Product Description

The ABB ohy65l10b is a pistol-style handle door-mount rotary operator designed for use with molded case circuit breakers and enclosed disconnect switches. The unit provides a direct-coupled external operating mechanism that allows the breaker to be switched on, off, or reset without opening the enclosure door. At 65 mm, the handle frame size matches corresponding ABB breaker mounting footprints. Electrical installers and panel builders use this operator when local codes or safety standards require a lockable, door-mounted disconnect point on industrial or commercial power distribution enclosures.

This operator is suited for industrial control panels, motor control centers, and commercial electrical distribution enclosures where an externally accessible switching mechanism is required. It is intended for installations where the rotary operator must remain accessible on the outside of the enclosure door while the breaker and live components stay protected inside. The pistol-handle configuration provides a positive grip for manual operation and supports lockout/tagout compliance in maintenance environments.

Key Features

• Pistol-style handle provides secure manual grip for switching and reset operations
• Door-mount design allows breaker operation without opening the enclosure
• 65 mm frame size matches corresponding molded case circuit breaker footprints
• Supports lockout/tagout (LOTO) procedures for maintenance safety compliance
• Emergency stop and reset capability accessible from outside the enclosure

Compatibility

Designed as an OEM-style door-mount rotary operator for 65 mm frame molded case circuit breakers used in industrial and commercial enclosed panel applications.

Installation Notes

Installation should be performed by a licensed electrician following applicable NEC requirements and enclosure manufacturer guidelines. De-energize and lock out the circuit before mounting the operator to the enclosure door or aligning the coupling to the breaker shaft. Verify the 65 mm frame alignment between the operator and breaker before securing the door hardware. Do not operate the handle under load unless the breaker and operator assembly are rated and configured for that purpose.
