Breakers

You can integrate the following circuit breakers. For more information Power Devices, refer to the Breakers’ manual.

The 3VA series is designed for use in applications with higher technical requirements and a rated current of up to 630 A. In addition to an increased switching capacity of up to 150 kA, these MCCBs come with an electronic trip unit (ETU), and an integration capability for metering and communication functions.

The current-limiting contact system furthermore ensures a very high switching capacity. ETUs guarantee reliable overload protection, short-term delayed or instantaneous tripping in case of a short-circuit, neutral conductor protection, and fault protection against ground.

Mobile test devices allow the checking and parameterization of ETU functions in MCCBs on site.

State symbols of the molded-case circuit breaker

Different states of the molded-case circuit breaker are represented as a circuit-breaker symbol. The state symbol of the molded-case circuit breaker indicates the position of the molded-case circuit breaker in the frame. You can see whether the molded-case circuit breaker is open or closed. The background color designates the status of the relevant message.

Condition Monitoring

Displays the health status and the remaining lifetime of the breaker.

This feature is available for devices with firmware version V4.4 or above.

3WL

3WL are air circuit breakers. They can transfer important information to the software to carry out diagnostics management, fault management, maintenance management, and cost center management.

Connect the 3WL air circuit breakers via COM35 or COM16. You can use any other gateway to establish the connection.

The circuit breaker status is displayed in powermanager and the measured values and can be switched with the appropriate authorization.

There are two switching functions:

ON - Select ON when the circuit breaker status is OFF or TRIPPED.
OFF - Select OFF when the circuit breaker status is ON.

For more information, refer to the 3WL/3VL system manual.

3WA

The 3WA circuit breaker is the new generation of air circuit breakers in the Siemens AG portfolio. It is based on the proven and robust design of its predecessor 3WL. 3WA supports Modbus TCP module COM190 for connecting to higher-level management systems. The technical data of the 3WA circuit breaker mechanics and the portfolio have been extended as compared with 3WL, and the electronic components have been completely redeveloped.

The 3WA circuit breaker is part of the product family of SENTRON protection, switching, measuring and monitoring devices and covers applications in the rated current range from 630 A to 6300 A.

AC devices are available as circuit breakers and non-automatic circuit breakers.
DC devices are only available as non-automatic circuit breakers.

The 3WA circuit breaker has the following characteristics:

Three sizes:

Size 1 with a rated current In from 630 A to 2500 A
Size 2 with a rated current In from 2000 A to 4000 A
Size 3 with a rated current In from 4000 A to 6300 A

3VA27

The 3VA27 molded case circuit breaker is a current-limiting circuit breaker with IEC certification and is an addition to the existing 3VA IEC portfolio.

Current-limiting molded case circuit breakers are defined as:

Circuit breaker that, within a specified range of current, prevents the let-through current from reaching the prospective peak value and which limits the let-through energy (I2t) to a value less than the let-through energy of a half-cycle wave of the symmetrical prospective current.

These are the positive characteristics of a protection device that is most frequently used on the outgoing side and that, like the 3VA27 molded case circuit breaker, is dynamically selective and current limiting in the event of a fault.

Current limiting means that the peak value of the prospective impulse short-circuit current ip is limited to a smaller let-through current iD. Effective current limitation means that the circuit breakers and busbar trunking systems can be constructed more compactly. In the event of a short-circuit, the molded case circuit breaker substantially reduces the magnitude of the letthrough currents, that is reduces the load reaching downstream equipment (less thermal load, lower dynamic forces). The let-through energy is also significantly reduced. 3VA molded case circuit breakers are designed to be current limiting.

It has the following characteristics:

Frame size 1600 A with a rated current In of 800 A to 1600 A
Choice of two designs:

as a toggle operating mechanism, e.g. as an additional manual operating mechanism
as a stored energy spring mechanism for integration of internal spring charging motors (external dimensions are not affected by this)

Optionally available either as a fixed-mounted version or as a withdrawable version. An especially high Icu value (up to 110kA @415V) and an Icw value (up to 20kA 1s).
