ABB PS2-4-2-125 Industrial Power Supply Module

ABB PS2-4-2-125 is a 125 A busbar rail accessory for ABB's PS2 motor protection system, engineered to accommodate four MS165 or MO165 motor circuit-breakers on a single PS2 mounting arrangement. It provides two lateral auxiliary contacts—one for general signaling and one specifically for trip signaling—facilitating coordinated protection and clear status indication across all four devices. This accessory enables compact, centralized motor protection within ABB PS2 panels, simplifying wiring and improving fault visibility in multi-motor installations. Ideal for industrial automation environments that deploy ABB MS165/MO165 protection devices on a PS2 architecture, the PS2-4-2-125 supports streamlined installation and consolidated control signaling for reliable, scalable motor protection.
