The ABB CT-ERE is an electronic on-delay time relay designed for precise timing control in industrial and marine automation systems. Onboard vessels, time relays of this type are installed in control panels, switchboards, and automation circuits to manage sequenced operations — including motor start delays, alarm inhibit timers, pump sequencing, and machinery interlocks. Manufactured in Germany to ABB’s industrial standards, the CT-ERE delivers reliable, repeatable timing performance suited to the demanding electrical environments found in engine rooms and deck control systems.
Key Features
✓ On-delay timing function with adjustable range of 3 to 300 seconds
✓ Dual supply voltage: AC 220–240V 50/60Hz (terminals A1/A2) and AC/DC 24V 50/60Hz (terminals A1/B1)
✓ Output rated ITHE 4A, UI 300V, UIMP 4kV with 10A fast fuse protection
✓ Contact ratings of AC15 230V 3A and DC13 24V 2A for direct control circuit loads
✓ Compact DIN rail mount design manufactured in Germany to ABB industrial quality standards
Marine Applications
Motor start sequencing and soft-start delay control in engine room automation and switchboard panels
Alarm inhibit and delay-on timers in fire detection, gas detection, and safety monitoring circuits
Pump sequencing and changeover timing in ballast, bilge, cooling water, and fuel transfer systems
Timing control for auxiliary machinery interlocks on cargo, tanker, and offshore support vessels
Control panel relay logic for HVAC, ventilation fans, and deck machinery automation systems
Why Marine Engineers Choose ABB CT-ERE
The ABB CT-ERE series is a widely deployed industrial time relay valued for its accurate on-delay timing, wide supply voltage compatibility, and straightforward DIN rail integration — enabling reliable replacement or retrofit into existing marine control panels without panel modification.
Ideal For
Cargo vessels, tankers, bulk carriers, container ships, offshore platforms, passenger vessels, tugboats, and any vessel requiring relay-based timing control within switchboard, automation panel, or machinery control room applications.
