L-Series Type Tested Panels

The L-Series panel system is the realisation of a vision that many claimed was impossible. From inception, flexibility has been the primary focus of the L-Series design.

Now, our decades of experience and expertise in design, engineering, manufacturing and after sales service has culminated in the development of this new AuCom global switchgear standard.

The L-Series is the most universal switchgear system on the market today.

AuCom L-Series panels are fully type tested according to IEC 62271-200:

Short time withstand current
Peak withstand current
Internal arc fault (IAC classification: AFL 31.5 kA for 1 second)
Dielectric test on main and auxiliary circuits
IP rating
Temperature rise test related to 50 °C ambient temperature and main circuit resistance
Certificates are available from AuCom on request.

If an arc event occurs within an AuCom L-Series panel, the arc fault is contained by solid locking doors and heavy double layer compartment panels.

During the emission phase, the pressure is safely released using discharge flaps on the top of the panel (or optional ducts), which direct the explosion upwards or vent it safely outside.

L-Series MVE panels are available in either IP4X or IP54 panels, with options for line and bypass devices, earthing and isolation switches. AuCom can also design and build panels to meet particular specifications, and we offer full application engineering support at all stages of the design process.

In addition to standard packages we can supply a complete line up to meet your requirements, including the following options:

• Top or bottom cable input (motor & control wires)
• Supply voltage: top, bottom or main busbar system
• Switching devices (line & bypass): vacuum contactor or circuit breaker
• Internal power factor correction with capacitor, vacuum contactor, fuses and inrush current limiter
• Control voltage source: internal via MV control transformer or external via customer terminal blocks
• Earthing/Disconnector: Input, output or main busbar system

The L-Series MVX soft starter is the smallest medium voltage soft-starter in its class, with a smaller panel footprint than any other MV soft starter in the market today. Space is a big advantage in lowering your switchroom costs and provides more flexibility where space is needed like marine applications.

To ensure your staff and plant are safe from arc fault, AuCom L-Series panels are the only choice. The L-Series panel system meets or exceeds all the relevant IEC standards for internal arc fault resistance. L-series MVX panels can even withstand an arc event in one compartment without affecting neighbouring compartments. Type tested panels meet Internal arc classification (IAC) AFLR to a maximum of 31.5 kA for 1 second.

AuCom has eliminated complex disassembly to replace or service a part. The L-series MVX panels are designed with easy rack-in, rack-out operation. Components can be inspected through viewing windows and are easily accessible via hinged doors or removable panels, while still keeping unauthorised people out.

Don't feel constrained in the choice of apparatus in your switchgear, AuCom panels are compatible with all of the major apparatus suppliers.

The L-Series MVX soft starter is available in a range of configurations up to rated voltage class 15 kVA and 450 A. AuCom has a full service capability to design and manufacture your entire Motor Control Centre.
