BESCHRIJVING

UPL11-1-52-502 is a two-pole hydraulic magnetic circuit protector designed for DC long-delay applications with a nominal amperage rating of 5.0 amperes. This device provides reliable power switching and circuit protection by opening contacts and returning the handle to the OFF position upon overload, ensuring trip-free operation even when the handle is held in the ON position. The protector features a DC long-delay characteristic (code 52) that allows controlled response to transient overcurrents while protecting against sustained faults. With a contact resistance of 0.059 ohms and impedance of 0.068 ohms at 5.0 amperes, the UPL11-1-52-502 is suitable for industrial control systems, motor protection circuits, and power distribution applications where reliable overload protection and manual switching are required.
