This Siemens 3VA9143-0JA12 is a terminal block accessory, part of the SENTRON product line. It is specifically designed for integration with 3VA6 150/250 circuit breakers, providing essential connectivity solutions.
The accessory supports a wide range of conductor cross-sections for copper cables, adhering to both IEC and UL standards. For IEC connections, it accommodates stranded copper cables from 6 mm² to 120 mm², with specified stripped lengths of 19 mm and tightening torques ranging from 6 Nm to 10 Nm depending on the conductor size and type (solid, stranded, or finely stranded).
Under UL standards, the terminal block accepts solid and stranded copper cables from 10 AWG to 3/0 AWG. The stripped length requirement is 0.75 inches, with tightening torques specified as 105 lb-in for solid and smaller stranded conductors, and 140 lb-in for larger stranded and finely stranded conductors.
This accessory is suitable for applications requiring robust and reliable electrical connections within the specified circuit breaker series.
According to IEC standards, this terminal block accessory supports stranded copper cables with a minimum cross-section of 6 mm² and a maximum of 120 mm².
The required stripped length for copper cables when using the IEC connection is 19 mm.
For solid copper cables ranging from 6 to 16 mm², the tightening torque is 6 Nm.
According to UL standards, this terminal block accessory supports solid and stranded copper cables from a minimum of 10 AWG to a maximum of 3/0 AWG.
The required stripped length for copper cables when using the UL connection is 0.75 inches.
For stranded copper cables, the tightening torque is 105 lb-in for sizes 10 to 4 AWG, and 140 lb-in for sizes 3 to 3/0 AWG.
The Moisture Sensitivity Level (MSL) is 1 Unlimited.
