The ABB CM-PFS is a phase sequence monitoring relay designed to protect three-phase AC electrical systems against incorrect phase rotation and phase order faults. Operating across a wide supply range of AC 200–500V at 50/60 Hz, it is suited for installation in marine switchboards, motor control centres, and distribution panels aboard commercial and industrial vessels. Correct phase sequence is critical to the safe operation of motors, pumps, fans, compressors, and other rotating machinery onboard — an incorrect phase order causes reverse rotation and can result in equipment damage or safety incidents. The CM-PFS provides automatic detection with a relay output to interrupt or signal the control circuit before harm occurs, making it a standard protective element in marine electrical installations.
Key Features
✓ Monitors three-phase AC systems for incorrect phase sequence across AC 200–500V, 50/60 Hz supply
✓ Relay output ratings: AC15 230V/3A and DC13 24V/2A for direct integration with control and protection circuits
✓ Insulation voltage UI: 500V and impulse withstand voltage UIMP: 4kV for robust marine electrical environments
✓ Internal thermal current ITHE: 4A with 6A fast-acting fuse protection for reliable overcurrent coordination
✓ Manufactured in Germany by ABB — engineered for long-term reliability in demanding industrial and marine automation applications
Marine Applications
Motor control centres and main switchboards requiring automatic phase sequence supervision
Pump and compressor drives where reverse rotation would cause mechanical damage or process hazards
Cargo handling equipment, winches, and deck crane drives sensitive to phase order
HVAC, refrigeration, and chiller systems aboard vessels requiring phase-correct three-phase supply
Auxiliary machinery panels, automation cabinets, and engine room distribution boards
Why Marine Engineers Choose ABB CM-PFS
The ABB CM-PFS delivers compact, reliable phase sequence protection backed by ABB’s established global marine and industrial support network. Its wide input voltage range, standard DIN-rail mounting, and clearly defined relay output ratings simplify integration into existing marine switchgear and control panels, reducing installation time and commissioning risk.
Ideal For
Cargo vessels, bulk carriers, tankers, offshore support vessels, ferries, naval auxiliaries, and industrial marine platforms requiring three-phase motor protection and phase sequence monitoring across switchboard, MCC, and control panel installations.
