What this terminal lug does that a standard connector won't
The 3VA9244-0JC13 is a SENTRON TA2.2 circular conductor terminal — a wire connector with an integrated control wire voltage tap-off. That tap-off means you pull a single lug for the main power cable and get a dedicated takeoff point for the breaker's control wiring, saving a separate splice or terminal block in the panel. Stripped length is 1.2 in — budget that when prepping cable ends. The connector is designed for 3VA6 150/250 A frame breakers; four units are supplied per order.
Wire range and torque — the practical limits
The 1.2 in strip length is non-negotiable: too short and the conductor may not reach the clamping zone; too long and bare copper sticks past the insulation, creating a creepage hazard inside the breaker compartment.
Lifecycle and sourcing — active, no drama
The 3VA9244-0JC13 carries an active lifecycle status from Siemens. No end-of-life notice, no successor part number to track. It is a current-production accessory for the SENTRON 3VA6 platform. Sourced to order against the BOM quantity through independent distribution.
