Siemens 3VA9153-0JA11 Frame Terminal for 3VA1 100/160 Circuit Breakers, 1.5-70mm2, 3-Piece Set

The Siemens 3VA9153-0JA11 frame terminal set is a high-quality accessory engineered specifically for 3VA1 100/160 molded case circuit breakers. This set includes three individual terminals designed to facilitate secure and efficient electrical connections within power distribution systems. By providing a robust interface for cables, these terminals ensure that the circuit breaker operates reliably under various electrical loads, maintaining the integrity of the connection in both industrial and commercial environments.

Advantages

These frame terminals offer significant benefits for electrical installations by providing a versatile connection range for conductors between 1.5 mm2 and 70 mm2. The design focuses on ease of installation and long-term mechanical stability, which is crucial for preventing loose connections and overheating. Using original Siemens components ensures full compatibility with the 3VA1 series, maintaining the safety standards and performance specifications of the circuit breaker unit.

Suitable for

• Industrial power distribution panels
• Commercial building electrical systems
• Upgrading or maintaining 3VA1 100/160 circuit breakers
• Applications requiring secure termination of copper or aluminum conductors

This product may not be suitable for circuit breakers outside of the 3VA1 100/160 series, as the mechanical dimensions and mounting interfaces are specific to this model. It is also not intended for use with conductors outside the specified cross-section range of 1.5 mm2 to 70 mm2.

Key specifications

• Compatible with: Siemens 3VA1 100/160 molded case circuit breakers
• Conductor cross-section range: 1.5 mm2 to 70 mm2
• Quantity: 3-piece set
• Application: Cable termination for power distribution

To install the frame terminals, ensure that the circuit breaker is completely disconnected from the power supply to prevent electrical hazards. Remove the existing terminal covers if necessary and insert the frame terminals into the designated slots on the circuit breaker. Secure the terminals according to the manufacturer's torque specifications to ensure a firm grip on the conductors. Once installed, insert the cables and tighten the screws to the required torque to establish a reliable electrical contact.

What to consider before purchase

• Verify the specific model of your circuit breaker to ensure it is a 3VA1 100/160 unit
• Check the cross-section of your cables to confirm they fall within the 1.5 mm2 to 70 mm2 range
• Ensure you have the correct tools for tightening terminal screws to the specified torque

Usage recommendations

Always follow the official Siemens installation manual for the 3VA1 series to ensure compliance with safety regulations and to maintain the warranty of your electrical equipment.
