Input Fuses and Circuit
Breakers
The 1336 IMPACT can be installed with either input fuses or an input
circuit breaker. Local/national electrical codes may determine
additional requirements for these installations.
Installations per U.S. NEC/UL/CSA
Fuses - In general, the specified fuses are suitable for branch short
circuit protection and provide excellent short circuit protection for the
drive. The fuses offer a high interrupting capacity and are fast acting.
Refer to the North American selections in Chapter 3 for A1-A4
frames and Chapter 4 for B-H frames.
Circuit Breakers - The Westinghouse HMCP breakers specified in
the following table provide branch short circuit protection. Because
circuit breakers are typically slower than fuses and those listed are
magnetic trip only, they may not be as effective in offering short
circuit protection to the drive in the event of an internal drive short
circuit. They may not be as effective in limiting damage to the drive.
IEC Installations
Fuses - For those installations that are not required to meet the U.S.
NEC/UL/CSA, the specified fuses are suitable for branch short circuit
protection and provide excellent short circuit protection for the drive.
The fuses offer a high interrupting capacity and are fast acting. Refer
to the European selections in Chapter 3 for A1-A4 frames and
Chapter 4 for B-H frames.
Circuit Breakers - For those installations that are not required to
meet the U.S. NEC/UL/CSA requirements, additional devices are
available as input circuit breakers. The Bulletin 140 and KTA3
devices meet the circuit breaker requirements. They can be used in
“non-U.S.” installations where local/national codes allow, if they are
installed per their installation instructions.
Recommended AC Line Circuit Breakers (User Supplied)

ATTENTION: The 1336 PLUS II does not provide
input power short circuit protection. Specifications for
the recommended fuse or circuit breaker to provide drive
input power protection against short circuits are
provided.
