With an Ith of 250 A, the OSP250D Fourth Pole enables robust protection for high-current main circuits and helps prevent overheating in demanding industrial environments. This capability translates into fewer unplanned shutdowns and safer startup transients in 690 V systems, supporting reliable operation of ABB OS/OSM switchgear. The 13 W power loss at rated current improves thermal management and energy efficiency, reducing cooling requirements and extending component life in compact control cabinets. DIN fuse type and screw mounting simplify installation and standardization across sites, while lug terminals and a tightening torque of 30–44 N·m ensure secure, vibration-resistant connections in harsh environments. Dimensions and weight (162 mm W, 72 mm H, 203 mm D; 1.2 kg) support efficient panel layouts, and the product is compatible with OS/OSM families for seamless replacements.
