Blue Sea 7149 200A Surface Mount Circuit Breaker

Description

The Blue Sea Systems 7149 is the surface mount 200 amp version of the 187-Series breaker, mounting on top of a panel or bulkhead rather than through a cutout. It combines switching and circuit protection in one device with clear single lever operation.

One caution comes with this rating that is worth heeding: do not use it as a switch where high inrush currents are expected. Inrush from a large inverter or motor start repeated through the breaker will wear the contacts far faster than the same current passing through a closed breaker. Use a proper switch for that duty and let this handle protection.

It is waterproof and ignition protected, meeting SAE J1171 external ignition protection requirements for gasoline powered boats. Recessed mounting holes keep the appearance tidy, the 5/16 M8 terminals take heavy gauge lugs with room to work, and the large lever shows trip status by its orientation. Trip free design prevents it being held on during a fault. Compare with our other marine circuit breakers.
