Description

Electronic Circuit Breaker

S8V-CP – Electronic Circuit Breaker

S8V-CP protects DC circuits very precisely. Overload and short circuits are accurately detected and reliably switched off

  • 4- / 8-channel electronic circuit breakers with adjustable tripping currents from 2 to 10 A
  • Thermomagnetic tripping characteristic
  • Sequential and load-dependent start-up of the outputs to avoid high inrush currents
  • Ability to switch-on high capacitive loads reliably
  • Backlit buttons with multi-color LEDs indicate the output status at a glance
  • Push-In Plus terminal blocks
  • Space saving Value Design for Panel
  • UL Class 2 model reduces the costs of applying a safety standard
