SIVACON low-voltage switchboard

Product Description

The SIVACON low-voltage switchboard is the standard solution for building and industrial technology.

SIVACON is tailored to the needs of the world market, i.e. it takes into account the call for standard solutions from a single source on the one hand and on the other for local production and the resulting advantages in terms of financing and procurement close to the plant.

As a power distribution board, SIVACON is available throughout the world and can be used at all power levels up to ***0 A, as withdraw able as well as plug-in and fixed-mounted units.

SIVACON Features:

• Type-tested standard modules

(TTA)

• Standardized busbar position at the top of the cubicle

• *- and *-pole busbar system up to ***0 A

• Rated peak withstand current Ipk up to **5 kA

• Deep switchgear compartment for universal installation Modular structure of device compartments

• Single-front and back-to-back installation

• Cable lead-in from above or below

• Cable connection from the front or rear

Modular technology makes it possible to adapt SIVACON optimally to all requirements.

• Standard horizontal busbar position at the top of the cubicle

• Any components can be installed in the device compartments regardless of the busbar position and cubicle depth

• Requirement-oriented compartmentalization of functional units (Form 1 to Form 4 according to IEC ******1)

• Deep device compartments

The frame consists of rigid sheet steel sections that are linked to one another: SIVACON’s dimensionally accurate and sturdy frame is available in bolted or welded versions.

Surface Treatment:

Optionally powder-coated, wet painted or sendzimir-galvanized

Frame and enclosure are manufactured from sheet steel in the following thicknesses:

Frame: 2.5 mm

Enclosure: 2.0 mm

Degrees of Protection to IEC ****9 IP *0, IP *1, IP *0, IP*1, IP *2 naturally ventilated IP *0, IP *4 unventilated

Differing requirements for the busbar system call for individual options.

SIVACON offers modules for economical setup and high level of safety.

• Busbar position at top

• Busbar system for rated currents up to ***0 A

• User-oriented gradation of rated currents

• Rated peak withstand current Ipk up to **5 kA

• Separation of the busbar compartment from the device compartment

• Transport unit joints easily accessible from above

• Arc barriers for limiting the effects of the arcing fault

The supply, feeder and coupling cubicles of the circuit-breaker design are equipped with withdrawable or fixed-mounted 3W. Circuit breakers (ACB). User-Friendly with 3W. Siemens 3W. fixed-mounted and withdrawable circuit breakers are used for the rated current range from **0 to ***0 A. This means:

• Free choice of the supply direction without any restrictions in terms of technical data

• High short-time current-carrying capacity for time-graded short-circuit protection up to **0 ms assures reliable operation of sections of the switchboard not affected by a short-circuit

• Short-circuit protection with short time grading control (ZSS) for very brief delay times (*0 ms), irrespective of the grading level

• LCD operating current indication in the control console (without ammeters and current transformers)

• Indication and operation when the door is closed

Cable or Busbar ConnectionCompartment

• Cable or busbar connection optionally from above or below

• A rated current-dependent connection compartment offers optimum termination conditions for cables and busbars

• Assembly times are shortened by optimum connection compartments

The cubicles for cable feeders in fixed mounted execution are equipped with molded-case circuit breakers or fuse switch disconnectors (conventional or in-line), depending on requirements. These cubicles are used for applications

in which replacement under operating conditions is not necessary or where short downtimes are acceptable. In this case, the SIVACON fixed mounted design offers excellent economy, safety and variability.

The in-line plug-in design outgoing feeders represent a low-priced alternative to the withdrawable-unit design. By virtue of the supply-side plug-in contact and their compact design, the modules provide the facility for easy and quick interchangeability without switchboard shutdown. With the in-line plug-in design, SIVACON offers good cost effectiveness, safety and flexibility.

SIVACON is a type-tested switchgear and control-gear assembly (TTA) whose physical characteristics were designed in the test laboratory both for normal operating conditions and for fault situations. Conclusive type tests assure a maximum of reliability and personal safety. SIVACON has passed the following verification tests as detailed in IEC ******1, DIN EN ******1 (VDE ***0 Part **0)
