SACE YU DELAY RELAY
REF.NO: FKM3098
The ABB SACE YU Delay Relay (Part No. 702209/805) is a timing and delay relay module designed for use with ABB SACE series circuit breakers and associated switchgear systems. Delay relays of this type are integral to marine low-voltage power distribution and protection panels, where controlled time-delayed switching is required to coordinate protection sequences, prevent nuisance tripping, and manage load sequencing in shipboard electrical systems. The YU accessory designation indicates its role as an undervoltage or delay release unit within the SACE breaker family, making it a critical component for safe and reliable operation across a wide range of vessel electrical installations.
Key Features
✓ ABB SACE series compatible delay relay module – designed for precise integration with ABB low-voltage circuit breaker systems
✓ Provides time-delayed release functionality – supports coordinated protection and controlled switching sequences in marine power distribution
✓ Robust industrial-grade construction – built to ABB’s standards for reliability in demanding shipboard electrical environments
✓ Plug-in accessory module format – designed for straightforward installation and replacement within compatible SACE breaker assemblies
✓ Part number 702209/805 – exact OEM reference for direct cross-referencing and compatibility verification with ABB documentation
Marine Applications
Low-voltage main switchboards and distribution panels requiring timed protection coordination
Auxiliary switchgear panels in engine rooms, cargo handling systems, and accommodation power circuits
Motor control centres (MCCs) where delayed release prevents spurious tripping during motor starting transients
Emergency switchboard systems requiring controlled sequence switching and protection grading
Generator protection and bus-tie breaker assemblies where delay coordination is critical to power management
Why Marine Engineers Choose
