Blue Sea 285-Series 60A Breaker wiring diagram

Surface-mount 60A thermal DC breaker, rated to 48VDC with 3000A interrupt capacity at 48V. Manual reset, trip-free operation and M6 studs. Its 60A rating is circuit protection, not the load current; do not operate it as a switch into high-inrush loads.

Installation notes

Before you install.

Open a question for model-specific guidance and sources.

Verified against the manufacturer's documentation (rev. 7184 official product specifications and 285-Series dimensioned drawing; no linked installation manual), checked 2026-10-01. Manufacturer documentation →

What does the 60 A rating mean?

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.

How is it connected?

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.

How do you check suitability?

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.

What happens after a trip?

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.

How is the installed breaker recorded?

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.
