Functionality & features

As industrial processes and IT applications

diversify, a secure power supply is becoming

an increasingly important asset in the drive

to cut production and maintenance costs.

In emergency situations, the system logic

of power distribution can become complex

with mechanical devices looking after the

making, breaking, conducting and isolating

of power. Loads may sometimes need to

be transferred from one supply to another

— this will be the case when energy use

is restricted or when the supply source is

overloaded.

High performance level

In change-over applications where the loaded switch

may need to be operated remotely, adequate durability

has been ensured by testing against the IEC 60947-6-1

standard in the specification of endurance requirements.

Utillisation categories:

− AC-31 for non-inductive or slightly inductive load

− AC-33 for motor loads or mixed loads including motors

ABB change-over switches are rated according to

IEC 60947-6-1 standard.
