Originaltext):
Maximum Surrounding Air Temperature: 45°C
•
• Use 75°C Copper Conductors Only
• Suitable For Use On A Circuit Capable Of Delivering Not More Than 5000 rms Symmetrical Amperes,
480 Volts Maximum when protected by Class J Fuses, see instruction manual for Branch Circuit Protec-
tion details.
Suitable For Use On A Circuit Capable Of Delivering Not More Than 30000 rms Symmetrical Amperes,
480 Volts Maximum when protected by Semiconductor Fuses by SIBA, Type 20 189 20.xx or by Buss-
mann, Type 170M13xx or Littelfuse, Type L70QSxxx, see instruction manual for Branch Circuit Protec-
tion details.
Details of the prescribed Branch Circuit Protection as specified in the below section 'Branch Circuit Pro-
tection' of this Report need to be marked in the instruction manual
• Integral solid state short circuit protection does not provide branch circuit protection. Branch circuit pro-
tection must be provided in accordance with the Manufacturer Instructions, National Electrical Code and
any additional local codes.
CSA: For Canada: Integral solid state short circuit protection does not provide branch circuit protection.
Branch circuit protection must be provided in accordance with the Canadian Electrical Code, Part I.
• For installations according to Canadian National Standard C22.2 No. 274-13:
• Control Circuit Overcurrent Protection Required
• WARNING – The opening of the branch circuit protective device may be an indication that a fault current
has been interrupted. To reduce the risk of fire or electrical shock, current-carrying parts and other com-
ponents of the controller should be examined and replaced if damaged. If burnout of the current element
of an overload relay occurs, the complete overload relay must be replaced.
• Only for use in non-corner grounded type WYE source not exceeding 277 V phase to ground
• Brake resistor ratings and duty cycle:
• Duty cycle 50%
• Max. 60 sec on-time / 60 sec off-time
