The ABB CA5-40E is a 4-pole auxiliary contact block (4 normally open contacts) designed to snap directly onto ABB A-series contactors. Rated at 690V AC with a thermal current of 16A, it extends contactor functionality for control circuit signalling, interlocking, and status feedback in marine motor control centres, main switchboards, and automation panels. Its compact, tool-free mounting design suits the space-constrained electrical installations common across commercial and offshore vessels.
Key Features
✓ 4-pole normally open configuration: Four NO auxiliary contacts for versatile interlocking and feedback wiring
✓ Rated voltage & current: Ui=690V AC, Ith=16A — suitable for demanding marine electrical environments
✓ Conductor compatibility: Accepts AWG 12–16 copper stranded or solid conductors, rated for 60/75°C service
✓ Precise termination torque: 7–9 lb.in (0.8–1 N.m) for secure, vibration-resistant terminal connections onboard
✓ Direct snap-on mounting: Fits ABB CA5/A-series contactors without additional hardware or tools
Marine Applications
Motor control centres (MCC) and main switchboards — auxiliary feedback and interlock signalling for motor starters
Engine room automation panels — status monitoring and alarm circuits for pumps, fans, and air compressors
Ballast and cargo control systems — control circuit expansion for electrically operated valves and actuators
HVAC and refrigeration plant control — sequencing and monitoring of fans, compressors, and chiller units
Deck machinery and crane control panels — auxiliary switching for winches, windlasses, and deck equipment motor circuits
