The device installs into Siemens P2, P3, P4, and P5 panelboards, switchboards, and motor control centers. Equipped with an ETU560 electronic trip unit, it delivers adjustable LSIG protection. The breaker offers a 65 kAIC rating at 480V and includes a digital display. This 3Poles 40A CB circuit breaker is designed for industrial and commercial electrical systems. It ensures reliable protection against overloads and short circuits. The robust construction meets standard safety requirements for high-performance applications.
Features
3VA6 Molded Case Circuit Breakers up to 600 A, ETU, 600 V, up to 150 kA
3VA6 molded case circuit breakers
The new 3VA6 molded case circuit breakers reliably perform all the tasks required for circuit protection and protection of starter combinations.
This series is designed for applications with increased requirements:
• Increased breaking capacity
• Integrated metering function
• Connection to a communication system
Features
The most important features of the 3VA6 series are:
• Compact dimensions
• 3 and 4-pole versions
• Four breaking capacity classes of 35 kA … 150 kA at 480 V and 18 kA … 50 kA at 600 V
• Fixed-mounting, plug-in technology, draw-out technology
• Electronic Trip Units
• Retrofittable communication for ETU 5-series and 8-series • Depending on the ETU: Integrated metering function
• AC applications
• No derating up to +50 °C
• Modular and easy-to-fit internal accessories with diverse functions
• Uniform accessories platform across all 3VA5/3VA6 molded case circuit breakers
Compact dimensions with function expansions
In addition to its expanded functionality, the 3VA6 molded case circuit breaker also comes with compact dimensions for fixed mounting, as a plug-in version and a draw-out version.
A cover size of 70 mm (up to 600 A) for the door cutout and a complete selection of breaking capacity classes from 35 kA to 150 kA at 480 V provide the necessary flexibility for planning. Despite its compact size, the circuit breaker offers the following benefits:
• Very high short-circuit breaking capacity
• Electronic trip units, versions with and without integrated metering function and optional communication interface
Electronic Trip Units (ETUs)
The current sensors of the 3VA6 comprise iron-cored transformers for the internal power supply and Rogowski coils for precise current measurement. Each transformer can be optimized accordingly for its specific task. Thanks to the high accuracy of current measurement, the 3VA6 molded case circuit breaker is suitable for power/energy measurement. In addition, finer adjustment of ground fault current monitoring is possible.
The Electronic Trip Units (ETUs) provide the following protection functions:
• Overload protection L (“L” = Long-time delay)
• Short-time delayed short-circuit protection S (“S” = Short-time delay) for time-selective response in case of a short-circuit
• Instantaneous short-circuit protection I (“I” = Instantaneous)
• Protection of the neutral conductor N against overload and short-circuit (“N” = Neutral)
• Protection against residual currents to ground (“G” = Ground fault)
• Ground fault detection (G alarm = ground fault alarm) does not trip the circuit breaker, but an indication is shown on the display and/or is communicated to higher-level systems via the communication path or EFB/MMB.
Energy management and communication The Electronic Trip Units (ETUs) provide the following energy management and communication functions:
• Metering function for current, voltage, power rating and energy
• Transfer of measured value data and breaker status information
• Remote parameter assignment of tripping thresholds and miscellaneous parameters
• Flexible use of digital inputs and outputs of the optionally available EFB300 external function box
• Commissioning/setting the plant topology and also individual breaker parameters with the “powerconfig” software package
• Testing and archiving with the TD300 and TD500 test devices (with powerconfig)
