Reliance Electric F52A0624 Duty Master Motor Controller

The Reliance Electric F52A0624 Duty Master Unibrake Kit is a braking accessory designed for Duty Master Type F motors, delivering a built‑in hold brake that engages when power is removed to provide a secure hold and controlled stopping. This kit is specified for 230/460 VAC operation and provides 6 ft‑lbs of braking torque, enabling reliable braking on mid‑range industrial loads with a compact footprint. Identified as Type F Size 50, the F52A0624 sits within Reliance Electric’s historic Duty Master line, a family of rugged AC motors and braking solutions built to withstand demanding industrial environments. Designed to be paired with compatible Duty Master motors, this unibrake kit offers a dedicated braking function without requiring external drive electronics, supporting safe power‑down hold and repeatable stop actions in standard 60 Hz systems. Because it is a dedicated brake accessory rather than a drive, it does not include drive electronics, making it suitable for retrofit projects where a reliable braking solution on 230/460 VAC Duty Master motors is required.
