DESCRIPTION

The UPL1-1-65F-203 is a single-pole hydraulic magnetic circuit protector designed for reliable power switching and circuit protection in 50/60 Hz AC applications. This device features a long-delay trip characteristic (code 65) with a nominal amperage rating of 0.203 A, providing overload protection while minimizing nuisance trips during normal load transients. The protector operates as a manual ON-OFF switch under normal conditions and automatically trips to the OFF position upon overload, remaining trip-free even if the handle is held in the ON position. With a coil impedance of approximately 600 ohms at 50/60 Hz and recommended torque specifications for M5 stud terminals (13–14 in-lbs) and 6-32 mounting inserts (6–8 in-lbs), this device is suitable for industrial control systems, motor circuits, and power distribution applications requiring dependable circuit protection and manual control.
