It comes as a pack of three units, each with an integrated control wire voltage tap-off, so you can pick off the line-side potential without a separate terminal block. This is not a general-purpose lug; it is a form-fit accessory specific to the 3VA1 160 platform. If you are building or servicing a panel with that breaker family, this is the connector that mates to the plug-in base. ## Wire range and termination specs The 300 kcmil upper limit covers most feeder and branch-circuit conductors for a 160 A frame breaker. The 4 AWG minimum means you are not terminating small control wires here — that is what the voltage tap-off is for.","metaTitle":"Siemens 3VA9153-0JC12 SENTRON TA2.1 Wire Connector, 4 AWG–30","metaDescription":"Siemens SENTRON TA2.1 wire connector (3VA9153-0JC12) for 3VA1 160 plug-in/withdrawable units.
