This CBS resistor is a low temperature rise load dump resistor. It has a rise of surface temperature of 50 K after 440 kW in 5 sec.
Two CBT 400 resistors mounted in a small load bank. The nominal power is 3 kW and the resistor works at 2.5kVAC:
Modification of a CCH resistor:
CCH-450C for direct mounting on a IP65 motor drive cabinet. The cables are taken directly in to the cabinet through a bushing with an O-ring gasket.
CCH 536 C IP65 resistor for mounting on a heat sink of a water cooled drive. The cables are taken out through the side of the resistor and sealed with an O-ring. Due to the heat sink mounting the load ability of the resistor is increased:
CBR resistor with ventilator cooling:
|Over Load||50*PN in 1 sec|
|Dielectric Strength||3500V AC|
|Thermo watch (optional)||200°C|
