Blue Sea 7183 50 Amp Circuit Breaker Surface Mount 285 Series

The Blue Sea 7183 50 Amp Circuit Breaker Surface Mount 285 Series is an industrial-grade thermal circuit breaker engineered for reliable protection in demanding electrical systems. This 50-amp rated breaker serves as a direct drop-in replacement for older 185-series circuit breakers, making it ideal for retrofit applications where equipment upgrades are needed without complete panel redesign. The "trip-free" design ensures the breaker cannot be held closed after a fault condition occurs, a critical safety feature that prevents dangerous override scenarios in high-reliability applications.

The 285-series thermal circuit breaker features a visible reset lever that clearly indicates open condition status, eliminating ambiguity during troubleshooting or system verification. At 50 amps, this breaker protects circuits carrying substantial electrical loads while maintaining responsiveness to overcurrent and short-circuit events. The surface mount configuration allows installation directly onto panel faces or equipment enclosures, simplifying integration into existing systems. Compact dimensions (5 x 2 x 8 inches) and lightweight construction (0.3 lbs) ensure minimal space requirements and easy handling during installation or maintenance.

This circuit breaker suits marine electrical systems, industrial control panels, power distribution enclosures, and any application requiring thermal protection in the 50-amp range. Equipment operators, marine technicians, industrial electricians, and maintenance professionals depend on Blue Sea Systems circuit breakers for consistent, predictable performance in critical systems. The 285-series design is recognized across marine, industrial, and renewable energy installations as a standard for reliable thermal protection.

Blue Sea Systems manufactures circuit protection devices to exacting standards, and the 7183 model carries the heritage of proven field reliability. As a verified replacement for legacy 185-series breakers, this product reduces downtime during upgrades and ensures compatibility with established system designs.
