Positioned as one of the high-power solutions in the ML-Series, it stands out from more compact models like the M-ACR (65A continuous) or the SI-ACR (120A continuous) by its ability to handle high-efficiency alternators and large battery banks. Its Magnetic Latching (ML) technology ensures very low current draw in both ON and OFF states, with only moderate draw during state changes, thereby optimizing battery life.\n\u003c\/p\u003e\n\n\u003ch3\u003eAutomatic management and advanced isolation features\u003c\/h3\u003e\n\u003cp\u003e\n    The ML-ACR 500A automatically combines batteries during charging and isolates them when no charge is detected. It can detect charge on both battery banks, ensuring efficient management. This model offers configurable isolation functions: Start Isolation (SI) temporarily protects house loads from engine circuit voltage drops and spikes during startup, preventing damage. Engine Isolation (EI) allows isolation of two running engines to protect their electronics and maximize alternator output. These features are critical for protecting sensitive onboard electronics. The relay can also be used to couple battery banks in emergency start situations. For lithium battery systems, the ML-ACR Li-Ion version is specifically designed, while this standard model is optimized for AGM\/GEL to AGM\/GEL or AGM\/GEL to lithium configurations.\n\u003c\/p\u003e\n\n\u003ch3\u003eDesign and control\u003c\/h3\u003e\n\u003cp\u003e\n    With a continuous current rating of 500A, an intermittent capacity of 700A (5 minutes), and a starting capacity of 1450A (30 seconds), this relay is built for high performance. It features 3\/8\"-16 tinned copper studs for maximum conductivity and corrosion resistance, and silver alloy contacts for high reliability when switching loads under voltage. A Contura remote control switch (PN 2146) is typically included, providing manual control with or without power and a \"LOCK OFF\" function for maintenance. A remote LED output indicates relay status (combined, isolated, voltage lockout, or SI\/EI isolation). Its dimensions are approximately 13.65 cm long x 9.53 cm wide x 5.08 cm high, and it meets CE, ISO 8846, and SAE J1171 standards for external ignition protection, with an IP66 rating.\n\u003c\/p\u003e","brand":"Blue Sea Systems","offers":[{"title":"12 V \/ Without","offer_id":55861154677076,"sku":"7620-BSS","price":297.08,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0988\/3274\/4788\/files\/01_-_Hero_-_BLUE_SEA_ML-ACR_Automatic_Charging_Relay_-_12V_DC_500A_7620-BSS_-_Ref_09eee2e2.jpg?v=1779203494","url":"https:\/\/skysat.fr\/en\/products\/blue-sea-ml-acr-automatic-charging-relay-500a-12v","provider":"Skysat","version":"1.0","type":"link"}
