Blue Sea 7700100 ML Solenoid 500A Manual Control

Description

The Blue Sea 7700100 ML Solenoid is a 500A magnetic-latching switch designed for high-current 12V battery and equipment circuits. It can switch engine, inverter, house, or emergency-combine loads remotely while still providing a manual override directly at the solenoid for local control and service isolation.

The manual knob allows operation with or without control power and includes a locked-off position for servicing. A Deutsch DTM connector provides a sealed low-current control connection, while a dedicated LED output can indicate switch state when used with an optional remote indicator. Tin-plated copper studs and silver-alloy contacts provide high conductivity and dependable switching of live loads.

The bi-stable magnetic mechanism draws no continuous coil current in either steady state and uses power only while changing position. Blue Sea rates the solenoid for 500A continuous service, 700A intermittent operation, and substantial short-duration cranking loads when installed with appropriately sized cable. For high-current 12V systems that need remote operation plus a local manual backup, the 7700100 provides a flexible switching solution. Browse more battery switches.
