It's an accessory for the 3VA6 150/250 molded-case circuit breaker family, adding a control-wire voltage tap-off point at the load-side lugs. That means you can pick up a control voltage directly at the breaker terminals without a separate tap block — saves a DIN-rail slot and a wiring step in the panel. Listed as current/active on the lifecycle status. No phase-out or last-time-buy notice.","metaTitle":"Siemens 3VA9144-0JH12 Box Terminal TS1.2, 10 AWG–3/0 AWG, 4","metaDescription":"Siemens SENTRON 3VA9144-0JH12 box terminal TS1.2 for 3VA6 150/250.
