PA31800RC - 1800 Amp Rating Column

PA31800RC - 1800 Amp Rating Column

Meet the PA31800RC rating column—a heavy-duty, high-capacity trip plug designed to handle the toughest industrial and commercial installations. With a nominal current of 1800 A and a 3-pole configuration, it integrates smoothly into 3-phase systems and delivers reliable protection at up to 600 V AC. The built-in thermal-magnetic trip unit ensures accurate response to both overloads and short circuits, while the adjustable magnetic tripping range (6,500–11,000 A) allows fine-tuning of protection thresholds. Because this column is designed for use with PHF and PAF circuit breaker frames, it gives you both flexibility and performance without compromise.
