Mitsubishi Electric N220RHKPUL Overload Relay

The Mitsubishi Electric N220RHKPUL is a TH-N series overload relay rated for 100–150 A. This device provides thermal overload protection for motor circuits by tripping when the running current exceeds the set threshold, helping prevent motor damage in control panels and other motor-control applications. As part of Mitsubishi Electric’s TH-N family, the N220RHKPUL identifies its model and current range within the lineup, offering a proven protection option for mid-range motors. Designed for industrial environments, this relay functions as the protective element in motor control schemes where reliable interruption of current is required to guard against overheating. By choosing a TH-N relay within the 100–150 A range, technicians align with Mitsubishi Electric protection standards and ensure consistent performance within compatible systems.
