Product details

Fits which breaker — 3VA6 150/250 frame

The 3VA9144-0JA12: This box terminal is designed for the Siemens 3VA6 molded case circuit breaker in the 150 A and 250 A frame sizes. It ships as a set of 4 units, enough for a 3-pole breaker with a neutral lug or for a 4-pole configuration. The terminal designation TS1.2 is the Siemens part marking — it matches the line-side and load-side lug wells on the 3VA6 150/250. No adapter plate or drill-out needed; it bolts directly to the breaker bus.
