Harsh-Environment DC Circuit Breakers
Built to resist vibration and corrosion in harsh environments. These circuit breakers protect against overload and short circuits in low-voltage automotive and other electronic applications. All are thermal, so they use the heat generated in overcurrent situations to trip the breaker.
Breakthrough current is the maximum current that the circuit breaker can safely stop in the event of a short circuit.
Push-pull button and lever style breakers can be used as an on/off switch.
IP66 rated circuit breakers protect against power jets of water.
IP67 rated circuit breakers protect against water submersion, corrosion, and power jets of water.
