The Siemens 3VA9244-0JC13 is a circular conductor terminal accessory, specifically a wire connector, designed for use with 3VA6 150/250 circuit breakers. This component facilitates secure connections for both copper and aluminum stranded conductors.
It supports a broad range of conductor cross-sections, accommodating copper and aluminum stranded cables from a minimum of 50 mm² up to a maximum of 240 mm². For connections made according to UL standards, the permissible conductor temperature is 75 °C, and the connectable conductor cross-section ranges from 2 AWG to 350 kcmil for both stranded and finely stranded copper cables, as well as stranded aluminum cables.
The connector requires a stripped length of 30.5 mm for IEC connections and 1.2 inches for UL connections. Tightening torque specifications are provided for copper cables, with 31.1 Nm for IEC connections (50-150 mm²) and 275 lb-in for UL connections (2 AWG - 350 kcmil).
This accessory is part of the SENTRON product line, offering reliable connectivity solutions for electrical installations.
The maximum connectable conductor cross-section for copper stranded cable is 240 mm² according to IEC standards and 350 kcmil according to UL standards.
The permissible temperature for connectable conductors according to UL 486A-486B is 75 °C.
The stripped length is 30.5 mm for IEC connections and 1.2 inches for UL connections.
The tightening torque for copper stranded cables is 31.1 Nm for IEC connections (50-150 mm²) and 275 lb-in for UL connections (2 AWG - 350 kcmil).
