The overview shows an extract from the full range of accessories. For more information
on the accessory components, refer to the circuit breaker catalog; see Chapter
Reference documents (Page 18).
Note
The internal and external accessories of the circuit breaker are
identical for all sizes,
with the exception of all accessories for which width is significant (e.g. arc chute cover).
This allows easy exchange of accessory components between different circuit breakers
of the 3WA series.
The following components are included with the 3WA circuit breaker as standard, in
contrast to its predecessor 3WL:
• First trip alarm switch S24 (1 changeover contact) for circuit breakers
• Shutter for guide frame
• Ready-to-close signaling switch S20
• Spring charge signaling switch for all circuit breakers with spring charging motor
• Internal current sensor for the neutral pole for 4-pole circuit breakers
