Victron Energy Cyrix-Li-load 12/24V-230A – Heavy-Duty Load Disconnect Relay for Lithium Systems (CYR010230450)

The Cyrix-Li-load 12/24V-230A is a smart high-current relay designed to disconnect heavy DC loads from Victron lithium battery banks during critical conditions. Controlled by a VE.Bus BMS, it automatically engages or disengages based on voltage thresholds and safety signals. This version supports a massive 230 A continuous current, includes a 1-meter control cable, and features LED diagnostics for operational feedback.

Main Features
- For 12V and 24V lithium battery systems with VE.Bus BMS
- 230 A continuous current rating
- Automatic disconnect under undervoltage or BMS fault signal
- LED status indicators for operational states and fault alerts
- Three automatic re-engagement attempts before lockout
- Comes with 1-meter control cable
- Low power draw: <4 mA when open
- Transient voltage suppression for safe switching
