Protection boards & Snubbers

COUGAR ELECTRONICS protection boards ARCRC enable to limit the surges generated at the terminals of a power switch, during the switching period.

ARCRC 1

ARCRC1 boards are specially designed for dual diode or thyristor
modules and IGBTs type M1 and M2

  • Resistor : Wirewound vitreous enamelled welded resistor Type RB60
  • Capacitor : Polypropylene capacitor, max. centre distance 38
  • Circuit : 2 channels, 1 common point
  • Direct connection : With steel hexagon spacer male/female M5 or M6
  • Indirect connection : male/female M4, M5 or M6 insulator or connection by wiring equipped with 6.35 faston terminal connectors.

ARCRC 3

ARCRC3 is adapted for more powerful “presspack” type components.

  • Resistor : Wirewound axial lead welded resistor Type RB58 or RB60 and Wirewound flat oval resistor 31W mounted on steel and brass spacers
  • Capacitor : Polypropylene capacitor, max. centre distance 51
  • Circuit : 1 channel
  • Direct connection : WThe RC input (potential) is directly connected on the
    heatsink rail or the RC output (2ndpotential) is connected by wiring equipped
    with 6.35 faston terminal connectors.
