The built-in diodes protect against voltage spikes and EMI, while the sealed top and bottom covers help keep dust and splashes out of the enclosure (not submersible). The kit also includes spare fuses and heat-shrink female spade connectors so you can finish most installs without hunting for extra parts.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the built-in diode design protect my electrical accessories?\u003c\/h3\u003e\n\u003cp\u003eThe relays in this FASTSTORM panel include high-speed suppression diodes that quickly clamp reverse voltage and reduce electromagnetic interference.
