Brake resistors are used in various applications
CCR resistors are low to medium power resistors with a power range between 140 W and 1045 W, they are perfect for many applications. The UL certification guarantees that they meet all safety requirements.
Aluminum is chosen as the material for the housings because it is non-corrosive, non-magnetic, non-sparking, lightweight yet durable, and is an excellent conductor of heat. The resistors are fully insulated and have no external live parts. The resistive element features Nickel-Chrome alloy that has very low thermal drift. The resistive elements are mica insulated for high dielectric strength.
Working voltages are UL: 600 VAC / 850 VDC. Depending upon resistance, the overload factor ranges from 7 to 15 times the nominal power rating over 5-second pulse/120s. Protection ratings for CCR resistors are IP54/IP65.
A thermal switch is available as an option for overtemperature signaling. OEM resistor versions are available on request.
Danotherm CCH resistors mainly serve for charging/discharging in DC-links and as brake resistors in small inverter drives.
