Egis Mobile Electric 8720-1440B Dual XD Flex 500A Battery Relay ACR Tinned Wire

The Egis Mobile Electric 8720-1440B is a dual-circuit XD Flex relay designed for advanced battery management in marine, RV, and mobile power systems. This flexible relay features two independent 500-amp circuits, each configurable as an Automatic Charging Relay (ACR) to intelligently manage charging between multiple battery banks. The unit comes with tinned wire leads for superior corrosion resistance in harsh marine environments and is supplied in bulk packaging.

Key Features:

• Dual 500-amp relay circuits with ACR functionality for automatic battery isolation and charging
• Configurable via dip switches - each position can function as a relay/battery disconnect, voltage sensing relay, or low voltage disconnect
• Sealed to IP67/IP6K9K rating with high-temperature electronics for mounting anywhere
• Tinned wire leads provide enhanced corrosion resistance in marine and harsh environment applications
• Stainless steel cable lug studs and self-locking flanged nuts for reliable connections
• LED indicators for visual device status monitoring
• Protective terminal cover with integrated label recesses for easy circuit identification
• Compact design offers 35-75% reduction in mounting space versus competitive solutions
• Expandable with optional link and cross-link busbars to additional XD relay units
• Gore-Tex vent regulates internal pressure to prevent moisture intrusion

The XD Flex series utilizes advanced bi-stable solenoid technology and silver alloy contact points for reliable high-amperage switching. The dual ACR configuration automatically connects batteries during charging and isolates them during discharge, preventing starter battery drain while ensuring all batteries receive proper charging. Ideal for multi-battery installations in boats, RVs, and off-grid power systems.
