<5> Maximum MCCB Rating is 15 A or 200% of drive input current rating, whichever is larger. MCCB voltage rating must be 600 Vac or greater.
Additionally, when using MCCBs for protection, the drive must be installed in a ventilated enclosure with minimum volume according the “Minimum
Enclosure Volume” column.
<6> Model 2A0002 requires Mersen (Ferraz) part number A6T6 for compliance.
<7> Models 2A0004 and 4A0004 require Mersen (Ferraz) part number A6T15 for compliance.
<8> Model 4A0005 requires Mersen (Ferraz) part number A6T20 for compliance.
<9> Model 4A0007 requires Mersen (Ferraz) part number A6T25 for compliance.

Drive Short-Circuit Rating
This drive has undergone the UL short-circuit test, which certifies that during a short circuit in the power supply the current
flow will not rise above 31,000 amps maximum at 240 V for 200 V class drives and 480 V for 400 V class drives.
• The MCCB and breaker protection and fuse ratings shall be equal to or greater than the short-circuit tolerance of the power
supply being used.
• Suitable for use on a circuit capable of delivering not more than 31,000 RMS symmetrical amperes for 240 V in 200 V class
drives (up to 480 V for 400 V class drives) motor overload protection.

CSA for Industrial Control Equipment
The drive is CSA-certified as Industrial Control Equipment Class 3211.
Specifically, the drive is certified to: CAN/CSA C22.2 No. 04-04 and CAN/CSA C22.2 No.14-05.
u
Drive Motor Overload Protection
Set parameter E2-01 (motor rated current) to the appropriate value to enable motor overload protection. The internal motor
overload protection is UL listed and in accordance with the NEC and CEC.
n
E2-01: Motor Rated Current
Setting Range: Model Dependent
Default Setting: Model Dependent
Parameter E2-01 (motor rated current) protects the motor if parameter L1-01 is not set to 0 (default is 1, standard induction
motor protection enabled).
