This Siemens SENTRON wire connector, model 3VA9373-0JB13, is an accessory designed for use with 3VA5 and 3VA6 series circuit breakers rated for 400/600A.
The TA1.5 terminal designation indicates its specific application. It is engineered to connect both stranded copper and aluminum conductors, with a supported cross-section range from a minimum of 50 mm² to a maximum of 300 mm² according to IEC standards.
For copper cables, both stranded and finely stranded conductors within the 50-300 mm² range require a stripped length of 28 mm and a tightening torque of 42.4 Nm. According to UL standards, the permissible temperature for connectable conductors is 75 °C, with a stripped length of 1.1 inches. The UL conductor cross-section range extends from 1 AWG to 600 kcmil for both stranded and finely stranded copper, and stranded aluminum conductors. The tightening torque for these UL specified ranges is 375 lb-in.
This accessory is crucial for ensuring secure and compliant electrical connections in power distribution systems utilizing Siemens 3VA breakers.
According to IEC standards, it accepts stranded copper and aluminum conductors from 50 mm² to 300 mm². Per UL 486A-486B, the range is 1 AWG to 600 kcmil for copper (stranded or finely stranded) and aluminum stranded.
The tightening torque is 42.4 Nm for copper cables (stranded or finely stranded 50-300 mm²) per IEC, and 375 lb-in per UL for 1 AWG to 600 kcmil.
The required strip length is 28 mm (1.1 inches) for proper installation.
It supports stranded copper and aluminum conductors, including finely stranded copper, per both IEC and UL standards.
The terminal block is supplied in a package of 3 pieces.
Per UL 486A-486B, the permissible conductor temperature is 75 °C.
Yes, the product introtext indicates it is designed for use with Siemens 3VA6 circuit breakers (400-600A).
