Siren Marine SM-ACC-ACRE-240 240V AC Shore Power Relay for Siren 3 Pro

The Siren Marine SM-ACC-ACRE-240 is a 240VAC Shore Power Relay designed to detect the presence and loss of AC shore power on boats equipped with 240-volt electrical systems. Built for permanent installation, this relay hardwires directly into your vessel's AC distribution panel, providing a clean, integrated monitoring solution for larger vessels and liveaboards.

This relay is the hardwired alternative to the Siren Marine Shore Power Sensor Plug, purpose-built for 240VAC shore power configurations. When integrated with the Siren 3 Pro vessel monitoring system, it delivers real-time alerts the moment shore power is disconnected or lost — helping protect refrigeration systems, battery chargers, bilge pumps, air conditioning, and other critical onboard equipment that depend on uninterrupted dockside power.

Key Features:

• 240VAC coil voltage — purpose-built for higher-voltage marine shore power systems
• 10A contact current rating — reliable switching for marine electrical applications
• Hardwired installation — mounts directly to AC distribution panel for a permanent, secure connection
• Compatible with Siren 3 Pro monitoring system
• Instant shore power loss alerts — receive notifications the moment dockside power is interrupted
• Hardwired alternative to the plug-in Siren Marine Shore Power Sensor Plug

Compact and easy to integrate, the SM-ACC-ACRE-240 is an essential accessory for any vessel owner who wants continuous, reliable monitoring of 240VAC shore power status from anywhere.
