The IUGH11-1-62F-15.0-91 is a two-pole hydraulic-magnetic circuit protector designed for reliable power switching and accurate overcurrent protection. It features a series trip configuration with push-on terminals and one toggle handle per pole for independent pole operation. Engineered for 50/60Hz systems, this protector has a current rating of 15.0A and incorporates a long delay curve with an added inertial delay ('F') to prevent nuisance tripping from temporary inrush currents. The unit is equipped with a white toggle handle marked 'I-O' for clear visual status indication. Its trip-free action ensures safety by opening the circuit during an overload even if the handle is held in the ON position, making it ideal for precision applications like medical instrumentation, data processing, and military equipment.
