Recommended Branch Circuit Protection Devices
Branch circuit protection must be installed on the input (line side) of the drive controllers. Input fuses
may be used on 1/2 hp to 500 hp drive controllers; circuit breakers may be used on 1/2 hp to 100 hp
drive controllers.

drive controllers.
Fuses
The fuses specified in Tables 1–3 (pages 113–114) are suitable for branch short circuit protection and
provide excellent short circuit protection for the drive. Fuses are recommended for ATV58 TRX Type H
and Type FVC drives when they are wall mounted.
provide excellent short circuit protection for the drive. Fuses are recommended for ATV58 TRX Type H
and Type FVC drives when they are wall mounted.
Circuit Breakers
Circuit breakers will also provide branch short circuit protection. Because circuit breakers are typically
slower than fuses, they are not as effective in limiting damage to the controller in the event of an internal
drive short circuit such as shorted bus connections, shorted input rectifier, or failure of the internal solid
state overcurrent protection circuit in the controller. Refer to the ALTIVAR 58 TRX Installation Guide for
Type H Controllers (VVDED397048US) for recommended circuit breakers and application
considerations.
