The Swift Kompany 4703-120 is a 120 amp surface mount thermal circuit breaker (also called a manual reset marine circuit breaker or DC battery circuit breaker). It protects high-current 12V, 24V and 48V DC circuits and also works as a manual on/off switch for isolating a circuit. It belongs to the 285-series, a sealed, weather-resistant breaker design.

Key Features:

• Surface mount design: round housing with a high-visibility on/off lever
• Sealed housing: protects against dust and water intrusion, with an IP67 ingress protection rating
• Manual reset: switchable, so the circuit can be isolated for maintenance
• High interrupt current: 5,000 A at 16 V DC and 3,000 A at 28 V DC, for circuits on large paralleled battery banks
• Terminals: 1/4 inch-28 stud terminals
• Hardware: self-locking stainless steel hardware and serrated flange nuts resist corrosion and vibration
• Ignition protected: suitable for closed compartments where explosive gases may be present

This breaker suits marine, RV, off-road and heavy equipment electrical systems. Use it as a resettable alternative to a fuse on high-amperage battery, inverter and winch circuits.
