Product details

The Siemens 3VA9503-0JB23 is a SENTRON TA3.1 circular conductor terminal — a wire connector designed as an accessory for the 3VA15/25 1000 molded-case circuit breaker family. It comes as a pack of three units, each accepting one cable.

Wire range and torque — what the ratings mean

Stripped length is 1.0 inch, which matches standard crimp and insertion tools for this class of lug-style connector. No control wire tap is integrated — this is a straight power connection, not a feed-through for auxiliary wiring.
