The Siemens 3VA9674-0JJ44 is a circular conductor terminal TA4.4 designed to terminate four cables, each ranging from 4/0 to 600 kcmil. It ships as a set of four units and is intended as an accessory for the 3VA55, 3VA65, and 3VA66 molded-case circuit breaker families. This terminal block is classified under Group Code P360 and Product Group 5386, placing it in the accessories and spare parts category for Siemens' 3VA series. The product class is B, meaning return is restricted — coordinate with your Siemens partner for any RMA process.
Export control is straightforward — AL: N, ECCN: EAR99 — meaning no special licensing is required for cross-border shipment outside embargoed destinations. This is the same part, different passport; a genuine Siemens terminal regardless of which authorized region it originates from.
Integration and fit
Each terminal accepts a single cable per port, with four ports per unit. The 4/0 to 600 kcmil range covers the heavy copper or aluminum conductors typical on the line side of 3VA55 and 3VA65/3VA66 breakers. The circular conductor design uses a compression-style lug interface — verify the lug barrel diameter clears your enclosure's gland plate before committing the panel layout. Packaging dimensions are 172 x 333 x 52 mm for the set of four units. This is a panel-mount terminal, not a DIN-rail accessory; it bolts directly to the breaker's line-side studs or bus bars. The 52 mm height means it fits within the standard 3VA breaker envelope without increasing the overall panel depth.
