1 DESCRIPTION

The Contactors KME are switching devices intended for squirrel cage motors:

start-up, switching off without pre-stopping 50/60 Hz AC mains at voltage

up to 690 V (utilization category AC-3) and for non-inductive or low-inductive loads,

resistance furnace (utilization category AC-1).

2 TECHNICAL DATA

KME contactors are mounted on a 35 mm DIN rail. They comply with the requirements

of IEC 60947-4-1:2018.

The contactor can be wired with aluminium or copper wires. At the same time

copper and aluminium conductors should not be simultaneously connected

to the same terminal.

The degree of protection provided by KME contactors enclosure is IP20 according

to IEC 60529:2013.

Main circuit parameters of contactors for loads of AC-3 and AC-1 categories,

conductor cross-section for control circuit, auxiliary circuit specications

are given in tables 1-3.

Additional accessories for KME contactors are given in Tables 1-3.

To increase the number of auxiliary contacts, the design of KME contactors allows

the simultaneous installation of one front attachment PKE and an additional side

attachment KB.

A three-pole RTE thermal relay is installed in addition to the KME contactor

for motor protection against overloading, overcurrent and phase failure.

To delay on and off time of auxiliary circuit of contactors from 0,1s to 180s the front

pneumatic time delay attachment PVE is used.

Contactor accessories must be ordered separately.
