The Siemens SENTRON 3VA9132-0JF60 is a TA2.5 wire connector — a circular-conductor terminal block that terminates six cables and ships as a two-unit pack. It is an accessory for the 3VA5 125 molded-case circuit breaker family.
Stripped length and panel fit
Stripped length is stepped: 0.47 in for the smaller conductors, 0.9 in for mid-range, and 1.55 in for the largest 2 AWG terminations. No control-wire tap is included — this is a straight power connector, not a feed-through terminal with a test point.
