The Swift Kompany 4704-040 is a 40 amp surface mount 87 Series thermal circuit breaker (manual reset). It protects marine, RV and other DC electrical systems from short circuits and overcurrent loads. It also keeps wire insulation from overheating. The 48 VDC rating covers 12 and 24 VDC systems and adds protection for 36 and 48 VDC systems.

Key Features:

• 40 amp continuous current rating
• Surface mount design with a reinforced mounting tab to hold up under vibration
• IP66 sealed against dust and water intrusion
• 48 VDC maximum voltage rating
• High interrupt capacity: 5,000 A at 14 VDC and 3,000 A at 28 VDC, suited to circuits fed by large paralleled battery banks
• 2,000 cycles of electrical and manual switching endurance at full current
• Combines automatic circuit protection with manual on/off switching, which lets you isolate circuits for maintenance
• Corrosion and vibration resistant for harsh environments

This breaker is a compact way to protect high-current loads. It suits boats, RVs and other 12 to 48 VDC applications.
