A three‑pole Allen‑Bradley 140MG‑G8P‑D10 Motor Circuit Protector (MCP) from the 140MG G‑frame, it is a 100 A device designed for 3‑phase motor circuits up to 480 V AC. This magnetic‑only protector provides instantaneous protection for motor circuits (no adjustable thermal overload) and carries a short‑circuit current rating up to 65 kA at 480 V, making it suitable for rapid interruption during faults. UL 489/CSA listed, it is intended for panel installations in motor control applications to safeguard motors and feeders in 3‑phase systems while enabling fast disconnection on short‑circuit events.
