Blue Sea 285-Series 60A Breaker wiring diagram

The 7184 is a surface-mounted, manually reset 60 A thermal breaker for circuits up to 48 V DC. Its manufacturer specification gives 3000 A interrupt capacity at 48 V. The 60 A value is circuit protection, not the equipment’s operating current; do not use it as the load in an energy budget.

Install it in the protected positive feed and keep the source-side unprotected cable appropriately short. It uses M6 studs, accepting 1/4-inch ring terminals, with 5.65 Nm published stud torque. Support the cables so their weight does not twist the studs or case. The official dimension drawing supplies mounting dimensions; Blue Sea links no separate installation manual for this SKU.

Check load current, conductor ampacity, system voltage and available fault current independently. A thermal trip is affected by temperature and duration; it is not a precision current limiter. Do not assume its interrupt rating is sufficient for every lithium bank merely because the operating voltage is 12 V.

The lever displays the open condition and the mechanism is trip-free. Find the overload or wiring fault before resetting. Blue Sea permits switching use but excludes switching into high-inrush loads; use an appropriate disconnect/precharge arrangement where required. Repeated tripping should prompt current, connection-temperature and cable checks, not an automatic upgrade to a larger breaker.

Set the protected cable’s protection override to 60 A to record this hardware rating. The component’s name and switch symbol alone do not establish a 60 A protection setting in the planner. Check the actual breaker’s interrupt rating and trip curve separately; the software does not simulate its thermal trip timing.
