Area of application
Vacuum contactors 3TM are 1-pole switching devices with an electromagnetic op-
erating mechanism for high switching capacity and a rated voltage range from
4.15 kV to 6.9 kV (single-phase, rigidly earthed star point).
Vacuum contactors 3TM comply with the protection class IP00 (stationary, weather-
protected operation) as per EN 60529 and can be used
•
with circuit breakers and fuses,
•
for ambient temperatures from -40 °C to +70 °C,
•
at various altitudes ranging from -1250 m to 5000 m ASL,
•
for high mechanical vibrations or
•
for use in seismic zones,
•
on ships below deck,
•
on open pit or mining equipment,
•
in stationary or moving rail operation.
The technical data are affected by ambient conditions, installation position, and in-
stallation volume.
Operational currents and overload currents are switched by the vacuum contactor.
3TM vacuum contactors operate in continuous, periodic, and short-term operation.
Suitable for high frequency of operation and unlimited on-time.
Vacuum contactors 3TM are suitable for switching any type of alternating current cir-
cuits under normal operating conditions, such as:
•
Motors
•
Transformers
•
Resistor consumers
•
Neutral earthing
The vacuum contactor can be mounted:
•
as a fixed installation (with busbars or cables with cable lugs),
•
on a withdrawable part, or
•
on a carriage.
