Isolation 4000 volts
I²T fuse For 50 amp model: 63A or less, for example: Bussmann 63FE. For 75 or 100 amp model: 100A or less, for example: Bussmann 100FE. For installations >75 amps, or in warm installations, an external I²T fuse and fuse block can be used and a Power-io bus bar can be inserted in place of the internal fuse. See our fuse bulletin.pdf for additional fuse information.
Turn-on time <8.3 ms at 60hz
Turn-off time <8.3 ms at 60hz
Control Terminals Will accept #24-#10 AWG wire. Torque: 7-9 inch lbs.
Power Terminals Will accept #8-#3 AWG wire. Torque: 40 inch lbs.
Installation Leave a minimum of one inch below and 4 inches above these contactors for air ventilation. Leave one inch horizontally between units for air ventilation.
