Installation site

Observe distances according to IEC 60071 insulation co-ordination or comply with
the required air distances depending on the national operational requirements.

- Front side: High-voltage section with protection class IP00.
- Rear side: Low-voltage section with protection class IP20.

Installation site

The vacuum contactor 3TM can be installed in four positions.

Fig. 8

Installation site

1)

Wall mounting, vertical

2)

Supine position, horizontal

3)

Wall mounting, vertical, rotated 180°

4)

Suspended, possibly with reduced parameters (after consultation with manufacturer)

*)

Observe distance to high-voltage and grounded components!

High-voltage section

The high-voltage section consists of autonomous pole shells, which can receive the
correspondingly dimensioned vacuum interrupters. This makes variable distances
between the pole centres possible (120 mm and 150 mm).

Solenoid actuator

The vacuum interrupters are actuated by a common solenoid actuator. This solenoid
actuator has a very low holding capacity in continuous operation. The vacuum inter-
rupters work synchronously in the same direction.

The solenoid actuator and the shunt release of the vacuum contactor 3TM can be
actuated with AC or DC.

Vacuum contactors 3TM work according to a defined closing and opening time,
which can be configured and extended by an additional closing and opening delay.
Both delay values are independent of each other and are added to the closing and
opening times.

Electronic controller

The electronic controller controls the supply of energy to the solenoid actuator on
closing. The closing current is controlled to a specified level. The current is switched
to the holding current after a specified time. The holding current reduces the vacuum
contactor’s energy supply during operation.

The voltage supply of the magnetic unlatching is not affected. The customer is to
deal with the signal control. The maximum signal duration is to be observed, since
the shunt release solenoid only has a limited continuous current strength of 500 ms.

The inrush current (peak) is dependent on the supply voltage.

Supply voltage terminals

The electronic controller has terminals for the following:
• supply voltage A1/A2

as well as independent thereof

• the release voltage for the magnetic unlatching E1/E2 (optional).
