*Note 1 Short Circuit Co-ordination—max fuse ratings for Type 2 pass at 32-50kA prospective current.				Notes Rating are valid over a frequency range of 40-60 Hz, for other frequencies consult the sales office. Rated insulation voltage (Ui) is 660V for all devices. Coil consumption is listed in apparent power (VA). To determine the current at any particular voltage use the following formula : I = VA/V
