Abb OHB145L12 Pistol Handle 145mm Rotary Disconnect

Product Description

The ABB OHB145L12 is a pistol-style handle operator designed for rotary disconnect switches. It provides a mechanical means of operating the rotary mechanism on an enclosure-mounted disconnect, allowing the switch to be turned on or off from outside the enclosure door. At 145mm in shaft length, it is suited for installations where the panel door depth requires an extended reach between the handle and the switch shaft. Licensed electricians and panel builders install this type of operator during switchgear assembly and service work on motor control centers, industrial control panels, and similar equipment.

This handle operator is used in commercial and industrial electrical installations where a rotary disconnect switch requires an external door-mount operating handle. It is commonly installed on enclosures housing disconnect switches in manufacturing facilities, mechanical rooms, and utility sections of motor control centers. The pistol grip design provides a positive grip and clear operating position feedback for the technician.

Key Features

• Pistol-style grip for positive, ergonomic operation of rotary disconnect switches
• 145mm shaft length accommodates enclosure doors with greater depth between handle and switch
• External door-mount design allows switch operation without opening the enclosure
• Compatible with ABB rotary disconnect switch operator shaft interfaces

Compatibility

Designed as an OEM-style handle operator for ABB rotary disconnect switches that accept a 12mm pistol handle interface with a 145mm shaft length. Consult the ABB rotary disconnect documentation to confirm shaft coupling compatibility before installation.

Installation Notes

Installation should be performed by a qualified electrician in accordance with the National Electrical Code (NEC) and any applicable local codes. De-energize and lock out the disconnect switch and all associated circuits before mounting or servicing the handle operator. Verify that the shaft length and coupling interface align correctly with the disconnect switch before securing the handle to the enclosure door. Do not force the operator onto a mismatched shaft, as this may damage the switch mechanism.
