Fuses, Fuse Holders & Breakers – Overcurrent Protection

The fuses, fuse holders, and breakers category provides critical overcurrent protection devices that safeguard solar power systems from electrical faults, short circuits, and overload conditions. Quality protection devices interrupt excessive current flow before wiring and equipment sustain damage, preventing fires and ensuring system safety. Modern overcurrent protection combines fast response times with appropriate interrupt ratings to handle the high fault currents present in battery-based solar systems.

Protection options include DC-rated fuses and breakers specifically designed for solar applications, with ratings spanning 1A to 400A+ for various circuit protection needs. Class-T fuses provide high interrupt capacity for battery and inverter connections, while ANL and MEGA fuses serve automotive-style applications. Circuit breakers offer resettable protection with toggle or rocker operation. Fuse holders accommodate inline, panel-mount, and busbar configurations with appropriate voltage ratings for 12V through 600V DC systems.

Featured products meet UL and NEC (National Electric Code) requirements for solar installations, with proper DC interrupt ratings often exceeding 10kAIC (Kilo-Amp Interrupting Capability). Key specifications include amperage rating, voltage rating, interrupt capacity, and mounting style. Breakers feature thermal-magnetic or hydraulic-magnetic trip mechanisms, while fuses provide sacrificial protection requiring replacement after operation.

Protection device selection considers circuit maximum current, available fault current, system voltage, and installation location requirements.
