Operation principle and hardware
description
Contents of this chapter
This chapter describes the intended use and construction of the semiconductor switch unit
ACS880-7407LC. The chapter also presents the type designation label and the type code.
Operation principle
The semiconductor switch unit protects the drive DC bus in a short-circuit situation. The
main component is a semiconductor DC breaker switch. The DC breaker switch breaks the
DC bus when it detects a fault current. This limits the current efficiently and rapidly due to
semiconductor technology. The DC breaker switch can be connected either to the DC+ or
DC- busbar.
•If it is necessary to break the fault current in both poles, it is possible to add two units (and
DC breaker switches) into the system, one connected to DC+ busbar and the other to DC-
busbar.
•Liquid-cooled
•Bidirectional functionality
•Three sizes
•When necessary, the unit can be equipped with fuses for backup protection (option +F260).
Refer to the appropriate requirements, such as, for example, the rule requirements of the
relevant classification society in case of marine projects.
•If isolation is required in addition to the short circuit and overload protection, it is possible
to combine the semiconductor switch unit with the DC incoming unit (ACS880-7207LC or
ACS880-7307LC).

Operation principle and hardware description 13
•The unit operates independently and does not require any external control system.
•The unit provides interfaces to external control systems for monitoring,
interlocking/triggering and configuration purposes.
Overview diagram of the drive system
This diagram shows an example multidrive. The supply unit connects the drive to the AC
supply network, and converts the voltage to DC. The DC bus distributes DC voltage to the
inverter units and other units that are optionally included in the delivery, such as a
semiconductor switch unit.

Type designation key
Type designation describes the composition of the unit in short. The complete designation
code is divided in subcodes:
•The first digits form the basic code. It describes the basic construction of the unit. The
fields in the basic code are separated by hyphens.
•The plus codes (or option codes) follow the basic code. Each plus code starts with an
identifying letter (common for the whole product series), followed by descriptive digits.
The plus codes are separated by plus signs.
