A leaf spring type wiper, with a ceramic handle is used to vary the resistance. The resistors are protected with a perforated, pressed steel cover and three laboratory terminals are provided so that the unit can be used as a series resistor or potential divider. These are ideal to provide variable Dimensions current outputs in all laboratory environments. Key Features Power Dissipation up to 10 Amps Tough Steel Box Construction 3 Terminals For Divider Use 10 Times Power - Short Time Operate up to 400C Custom Designs Welcome Current Rating A B C D E F 10 450 405 420 153 94 63 5 450 405 420 153 94 63 4 450 405 420 153 94 63 2 450 405 420 153 94 63 1 450 405 420 132 68 47 How to Order Most BF resistors are custom designed against customers required duty cycles.
