SIRIUS System Manual

3-110 GWA 4NEB 430 0999-02 DS 01

RC circuit The RC circuit is suitable:

• For reducing the rate of rise

• In RF damping

Effective suppression can be achieved for a wide range of applications.

Varistor circuit A varistor circuit can absorb a high level of energy and can be used for fre-

quencies from 10 to 400 Hz (stabilized drives). There is no limit below the

buckling stress.

3.4.7.5 Soldering pin adapter for frame size S00 (3RT19 16-4KA.)

Description The standard contactors of frame size S00 in the SIRIUS range can be sol-

dered onto printed circuit boards by means of the soldering pin adapter.

Soldering pin connection is possible:

• For contactors with an integrated auxiliary contact

• For contactors with an attached 4-pole auxiliary switch block

• For the reversing wiring of the S00 contactors. This involves carrying out

the reversing wiring before soldering it on the printed circuit board
