The Siemens 3VA9143-0JB11 is a wire connector accessory designed for use with 3VA6 150/250 circuit breakers. This component, part of the SENTRON product line, facilitates secure electrical connections.
According to IEC standards, it accommodates stranded copper conductors ranging from a minimum of 1.5 mm² to a maximum of 50 mm². The required stripped length is 18 mm. Tightening torques vary based on conductor type and size, with values ranging from 6.2 Nm for smaller solid and stranded conductors up to 13.6 Nm for 50 mm² finely stranded conductors.
UL standards specify permissible conductor temperatures of 75 °C. For copper cable, solid conductors can range from 14 AWG to 10 AWG, while stranded and finely stranded conductors can range from 14 AWG to 1/0 AWG. Aluminum cable compatibility includes solid conductors from 12 AWG to 10 AWG, and stranded conductors from 12 AWG to 1/0 AWG. Tightening torques under UL standards are specified in lb-in, with values from 55 lb-in for smaller conductors up to 120 lb-in for 1/0 AWG conductors.
This accessory is crucial for ensuring reliable and safe electrical installations when working with Siemens 3VA6 circuit breakers.
According to IEC standards, the maximum connectable conductor cross-section for stranded copper cable is 50 mm².
According to UL standards, the maximum connectable conductor cross-section for stranded and finely stranded copper cable is 1/0 AWG.
The permissible temperature for connectable conductors according to UL 486A-486B is 75 °C.
The required stripped length for IEC connections is 18 mm.
The required stripped length for UL connections is 0.7 inches.
The RoHS status is RoHS3 Compliant.
The Moisture Sensitivity Level (MSL) is 1 Unlimited.
