Siemens 3WY3112-1MA00 Arcing Contacts for 3WN Switch

The Siemens 3WY3112-1MA00 is a set of spare arcing contacts designed for the Siemens 3WN switchgear. These contacts are rated for AC 690/1000 V and are intended for use with rated uninterrupted currents ranging from 1250 to 2500 A, and up to 4000 A. For a 4-pole configuration, four sets of these arcing contacts are required.

These components are vital for the safe and reliable operation of 3WN circuit breakers, ensuring proper interruption of electrical arcs during switching operations. They are critical for protecting electrical systems from overcurrents and short circuits.
