Siemens 3WA3108 Series Circuit Breakers

The Siemens 3WA3108 series is a configurable circuit breaker family: each unit is built to an order-specific number, and this page documents 16 known 3WA3108 configuration patterns, including withdrawable circuit breaker without cradle, ul1066/iec60947-2, fs 1, 4-poles, n-pole left, in=800a; fixed-mounted circuit breaker, ul1066/iec60947-2, fs 1, 4-poles, n-pole left, in=800a up to 730v ac.

The dots or blanks in a pattern stand for order-specific characters — ratings, terminals and options chosen at purchase.

What if some characters of my 3WA3108 order number are unreadable?

Send a photo of the rating plate or nameplate to orderdesk@kkmsolutions.com along with what the unit does (voltage, current rating, mounting). We identify the configuration against manufacturer data and confirm the exact replacement before quoting — we never guess part numbers.
