Mounting location and function

The 3RV2 motor starter protectors/circuit breakers have three main contact elements. In order to achieve maximum flexibility, auxiliary switches, signaling switches, auxiliary releases and isolator modules can be supplied separately.

These components are easily fitted to the switches without the use of any tools according to requirements.

For overview see "SIRIUS 3RV2 motor starter protectors/circuit breakers up to 80В A" в†’ "Overview".

В В В 

Front side

Note:

  • A maximum of four auxiliary contacts with auxiliary switches can be mounted on each motor starter protector/circuit breaker.

Transverse auxiliary switches, solid-state compatible transverse auxiliary switches

1В NOВ +В 1В NC
or
2В NO
or
1 CO

An auxiliary switch block can be inserted transversely on the front. The overall width of the motor starter protectors remains unchanged.

Left-hand side

Notes:

  • A maximum of four auxiliary contacts with auxiliary switches can be mounted on each motor starter protector/circuit breaker
  • Lateral auxiliary switches (two contacts) and signaling switches can be mounted separately or together
  • Signaling switches cannot be used for 3RV27 and 3RV28 circuit breakers

Lateral auxiliary switches (two contacts)

1В NOВ +В 1В NC
or
2В NO
or
2В NC

One of the three lateral auxiliary switches can be mounted on the left side per motor starter protector/circuit breaker. The contacts of the auxiliary switch close and open together with the main contacts of the motor starter protector.

The overall width of the lateral auxiliary switch with two contacts is 9В mm.

Lateral auxiliary switches (four contacts)

2В NO + 2В NC

One lateral auxiliary switch with four contacts can be mounted on the left side per motor starter protector. The contacts of the auxiliary switch close and open together with the main contacts of the motor starter protector.

The overall width of the lateral auxiliary switch with four contacts is 18В mm.

Signaling switches

Tripping 1В NOВ +В 1В NC
Short-circuit 1В NOВ +В 1В NC

One signaling switch can be mounted on the left side of each motor starter protector.

The signaling switch has two contact systems.

One contact system always signals tripping irrespective of whether this was caused by a short circuit, an overload or an auxiliary release. The other contact system only switches in the event of a short circuit. There is no signaling as a result of switching off with the handle.

In order to be able to switch on the motor starter protector again after a short circuit, the signaling switch must be reset manually after the error cause has been eliminated.

The overall width of the signaling switch is 18В mm.

Right-hand side

Notes:

  • One auxiliary release can be mounted per motor starter protector/circuit breaker
  • Accessories cannot be mounted on the right-hand side of the 3RV21 motor starter protectors for motor protection with overload relay function

Auxiliary releases

Shunt releases

For remote-controlled tripping of the motor starter protector. The release coil should only be energized for short periods (see circuit diagrams).

or

Undervoltage releases

Trips the motor starter protector when the voltage is interrupted and prevents the motor from being restarted accidentally when the voltage is restored. Used for remote-controlled tripping of the motor starter protector.

Particularly suitable for EMERGENCY-STOP disconnection by way of corresponding EMERGENCY-STOP pushbuttons according to DIN EN 60204‑1.

or

Undervoltage releases with leading auxiliary contacts 2 NO

Function and use as for the undervoltage release without leading auxiliary contacts, but with the following additional function: the auxiliary contacts will open in switch position OFF to deenergize the coil of the undervoltage release, thus interrupting energy consumption. In the "tripped" position, these auxiliary contacts are not guaranteed to open. The leading contacts permit the motor starter protector to reclose.

The overall width of the auxiliary release is 18В mm.

Top

Notes:

  • Isolator modules cannot be used for 3RV27 and 3RV28 circuit breakers
  • Isolator module for size S2:
    • only with 3RV2 motor starter protectors/circuit breakers up to max. 65В A
    • not with the transverse auxiliary switch
  • Terminal screws of the transverse auxiliary switch are covered by the isolator module;
    Recommendation: Lateral auxiliary switches should be used in combination with the isolator module, or the isolator module should not be mounted until the auxiliary switch has been wired up

Isolator modules

Isolator modules can be mounted to the upper terminal end of the motor starter protectors.

The supply cable is connected to the motor starter protector through the isolator module.

The plug can only be unplugged when the motor starter protector is open and isolates all 3 poles of the motor starter protector from the network. The shock-protected isolation point is clearly visible and secured with a padlock to prevent reinsertion of the plug.



For a complete overview as a PDF of which accessories can be used for the various motor starter protectors, see "SIRIUS 3RV2 motor starter protectors/circuit breakers up to 80В A" в†’ "Overview".
