Description:
The WLETO 40A DC12-48V Mini Circuit Breaker delivers marine-grade circuit protection with manual reset functionality. Engineered with copper contacts and waterproof housing, this C-curve breaker withstands saltwater corrosion, vibrations, and extreme temperatures while providing 3KA breaking capacity for 12-48V DC systems.
Features:
Marine-Proof Housing: IP68-rated waterproof design resists submersion and salt spray
Precision Protection: C-curve tripping characteristic (6-10x In) for sensitive electronics
Copper Conductivity: Oxygen-free copper terminals minimize voltage drop (<1%)
Universal Voltage: 12-48V DC compatibility for batteries/solar/RV systems
Tool-Free Operation: Manual reset lever enables instant recovery after fault clearance
Intelligent Protection:
Triple-safeguard mechanism:
Magnetic-hydraulic trip for overload/short-circuit (3KA breaking capacity)
Arc-extinguishing chamber prevents contact welding
Mechanical lock prevents accidental reset during faults
