Overview

The ABB OHB125L10 (SKU: OHB125L10) is a black, padlockable operating handle from ABB Electrification, designed for enhanced safety and operational control in industrial electrical systems. This handle offers a high degree of protection with IP65, NEMA 1, 3R, and 12 ratings, ensuring reliable performance in challenging environments. It is specifically engineered for compatibility with ABB OTDC switches, including models OTDC S1.0 (OTDC100…250E_, OTDC100…245U_) and OTDC S2.0 (OTDC100…250G_, OTDC100…250UG_), as well as OT16...100F switches rated for 20-100 A. The OHB125L10 features robust security with the capability to accept a maximum of three padlocks (bail diameter 5-8mm) in the OFF-position, preventing accidental energization during maintenance. A non-defeatable door interlock is integrated into the ON-position, ensuring the enclosure door cannot be opened while the switch is energized, thereby safeguarding personnel. The handle is constructed for double insulation, with screw fixing from the back to eliminate exposed screws on the front, contributing to a safer installation. Supplied as a single unit (1 pcs), this handle is manufactured in the USA and weighs 0.07 kg. Its black finish provides a professional aesthetic suitable for power distribution, industrial machinery control, and critical infrastructure applications where operational integrity and personnel safety are paramount.
