100-300A Manual Reset Circuit Breaker 12-48VDC Inline Fuse Block 0-8 AWG

100-300A Manual Reset 12-48V DC Inline Fuse Block 0-8 AWG Auto/Marine

Description:

Universal High-Current Protection for Auto/Marine Systems:
Designed for 12-48V DC vehicles (cars, RVs, boats), this manual reset circuit breaker handles 100-300A loads. Replaces traditional fuses for winches, inverters, and auxiliary batteries with instant overload response across extreme temperatures (-32°C to 82°C).

Hydraulic-Magnetic Trip and Manual Reset:
Patented hydraulic-magnetic mechanism combines quick short-circuit response (3kA breaking capacity) with time-delay overload protection. Manual reset lever prevents automatic re-engagement – critical for diagnosing faults in automotive/marine power systems.

Heavy-Duty 0-4 AWG Terminal Capacity:
Accommodates 0-4 gauge wires via corrosion-resistant brass terminals. Exceeds SAE J1128 standards with vibration-proof M8 studs, eliminating voltage drops in high-current applications like truck trailers or marine thrusters.

DIN Rail Mounting and Compact Integration:
Tool-free DIN rail clip enables rapid installation in panels or enclosures. Space-efficient design consolidates circuit protection without clutter – ideal for dual-battery setups, solar controllers, or aftermarket lighting systems.

48V DC Certified Safety Compliance:
Meets UL 1077/CE/ROHS with flame-retardant ABS housing. Rated for 48V DC systems (50/60Hz compatible), featuring arc-quenching chambers and thermal stability for lithium or lead-acid batteries in harsh environments.
