Blue Sea Systems 7148BSS 187 Series Thermal DC Circuit Breaker - 150 Amp Surface Mount

The Blue Sea Systems 7148BSS is a heavy-duty 187 Series thermal DC circuit breaker designed for marine and automotive electrical systems. Rated for 150 amps at 48 volts DC, this surface-mount circuit breaker provides reliable overcurrent protection with manual reset capability.

Key Features:

• 150 amp capacity at 48V DC for high-current applications
• Thermal trip technology provides consistent, temperature-compensated protection
• Surface mount design for easy installation on panels or bulkheads
• 5/16 inch-18 stud terminals for secure wire connections
• Switchable with manual reset - can be used as both a switch and circuit protection
• Single pole configuration
• Trip-free design prevents holding in ON position during overload
• Ignition protected for safe use in gasoline engine compartments

Blue Sea Systems 187 Series circuit breakers are known for their durability and reliability in harsh marine environments. The thermal mechanism responds to sustained overcurrent conditions while tolerating brief surge currents typical in motor and inverter applications. Ideal for battery distribution systems, inverters, windlasses, thrusters, and other high-current DC loads.
