Implementing thermal overload and short circuit protections

Protecting the input power cable against thermal overload

Diode supply unit

Equip the input cable with fuses or circuit breaker to protect the cable in a short circuit, and
against thermal overload. Obey the local regulations when selecting the protection.

WARNING!

If you use parallel cables, make sure that each conductor is protected individually.

IGBT supply unit

If the cables are dimensioned according to the nominal current of the drive, the drive thermal
overload protection protects also the input power cables against thermal overload. No
additional thermal protection devices are needed.

Protecting the input power cable in short-circuits

Diode supply unit

Equip the input cable with fuses or circuit breaker to protect the cable in a short circuit, and
against thermal overload. Obey the local regulations when selecting the protection.

WARNING!

If you use parallel cables, make sure that each conductor is protected individually.

IGBT supply unit

Equip the input power cable with fuses or a circuit breaker to protect the cable in a
short-circuit situation. Select the fuses according to the short-circuit strength of the cable,
and its supports, etc.

Protecting the drive against thermal overload

Cabinet-installed multidrives

The drive is equipped with thermal overload protection as standard. No additional protection
devices are needed.

Multidrive modules

Drive with a diode supply unit

Equip the diode supply unit with the ABB-specified input fuses for the thermal overload
protection and short circuit protection. See the diode supply module hardware manual.

The inverter units protects themselves against thermal overload. No additional thermal
overload protection devices are needed.

Drive with an IGBT supply unit

The supply unit protects itself against thermal overload. No additional thermal overload
protection devices are needed.

The inverter units protects themselves against thermal overload. No additional thermal
overload protection devices are needed.
