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 2
ARCRC1 boards are specially designed for dual diode or thyristor
modules and IGBTs type M3 and M4
- Resistor : Wirewound vitreous enamelled welded resistor Type RB60
- Capacitor : Polypropylene capacitor, max. centre distance 56
- Circuit : 2 channels, 1 common point
- Direct connection : With steel hexagon spacer male/female M8
- Indirect connection : male/female M4, M8 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.
