Blue Sea 285-Series 25–150A Circuit Breaker Identification Guide

Identify an existing Blue Sea 285-Series circuit breaker by its stamped part number, rated current and how it mounts. 708x numbers are panel-mount styles, while 718x numbers are surface-mount styles. The series covers 25A through 150A. This guide compares the exact models found in UsedRVParts and helps distinguish breakers that share the same amperage but use different mounting arrangements.

Identify the panel and surface versions

The 285-Series is a manually resettable, switchable DC circuit breaker, with a trip-free operating mechanism. Both mounting forms protect one electrical circuit; the different part-number series indicate how the breaker is installed, not a change to its nominal amperage within a matching pair.

7087 / 7088 / 7089: panel mount

Mounting uses a panel opening. Check the factory cut-out dimensions and lever clearance before replacing the panel-mounted breaker.

7187 / 7188 / 7189: surface mount

Mounting to a suitable surface avoids relying on the panel cut-out of the 708x versions. Confirm fastening and cable clearance.

Blue Sea model Rated current Mounting Main connections Maximum voltage
7087 100A Panel mount M6 terminal studs 48V DC maximum
7187 100A Surface mount M6 terminal studs 48V DC maximum
7088 120A Panel mount M6 terminal studs 48V DC maximum
7188 120A Surface mount M6 terminal studs 48V DC maximum
7089 150A Panel mount M6 terminal studs 48V DC maximum
7189 150A Surface mount M6 terminal studs 48V DC maximum

Lower-current model pairs

These listed 25–80A breakers are additional options in the same family. Blue Sea makes the panel-mount 7082, but neither store currently lists it, so only 7182 has a linked 40A product below.

Current Panel mount (708x) Surface mount (718x) Terminal Voltage
25A 7080-BSS 7180-BSS M6 studs 48V DC max
30A 7081-BSS 7181-BSS M6 studs 48V DC max
40A Not listed 7182-BSS M6 studs 48V DC max
50A 7083-BSS 7183-BSS M6 studs 48V DC max
60A 7084-BSS 7184-BSS M6 studs 48V DC max
70A 7085-BSS 7185-BSS M6 studs 48V DC max
80A 7086-BSS 7186-BSS M6 studs 48V DC max

The listed models use M6 terminal studs and have a 48V DC maximum rating. Manufacturer pages do not consistently agree on a single terminal-torque value, so consult the latest instruction sheet for the exact supplied model and revision. Choose the current rating to suit the wire ampacity, protected load and available fault current, rather than upgrading to a larger breaker simply because it fits.

Important distinction: A 285-Series circuit breaker is not automatically interchangeable with a 187-Series breaker of the same amperage. The physical layout, terminal size, interruption specifications and mounting requirements must be checked against the original equipment.

Original Blue Sea drawings and specifications

Factory dimensions and model-specific details are published at 7087, 7187, 7088, 7188, 7089 and 7189. Check the model's manufacturer's drawing for installation clearance, lug connection and mounting details.

Electrical installation: Before replacement, isolate power sources and verify the circuit's prospective short-circuit current and protection requirements. Do not use these breakers for repeated switching of high-inrush equipment outside the manufacturer's intended use.
