The Siemens 3VA9243-0JA12 is a box terminal accessory, part of the SENTRON product line, specifically designed for use with 3VA6 150/250 circuit breakers. This accessory facilitates secure and reliable electrical connections.
It supports a wide range of conductor cross-sections for copper cable, both stranded and finely stranded, adhering to IEC standards from 25 mm² to 185 mm² and UL standards from 4 AWG to 350 kcmil. The accessory also specifies precise stripped lengths and tightening torques for both IEC and UL connections, ensuring proper installation and performance. For IEC connections, stripped length is 20 mm with torques of 6 Nm or 12 Nm depending on the conductor size. For UL connections, the stripped length is 0.8 inches with torques of 70 lb-in or 140 lb-in.
This component is crucial for building robust electrical systems where secure termination of large conductors is required. Its design ensures compatibility with specific Siemens circuit breaker models, simplifying integration into existing infrastructure.
The maximum connectable conductor cross-section for copper cable, stranded, according to IEC is 185 mm².
The minimum connectable conductor cross-section for copper cable, stranded, according to UL is 4 AWG.
The tightening torque for stranded copper cables between 25-35 mm² according to IEC is 6 Nm.
The stripped length for UL connections is 0.8 inches.
The RoHS status is RoHS3 Compliant.
The Moisture Sensitivity Level (MSL) is 1 Unlimited.
