The ABB 1SDA065971R1 is a 4-pole auxiliary switch in a 2NO-2NC contact configuration, designed for the T8 platform of air circuit breakers. This is the contact block that bolts onto the breaker mechanism to signal position or drive interlock logic — it's not a standalone switch, it's a breaker accessory.
