MILE AIS – PRIMARY AND SECONDARY DISTRIBUTION SYSTEMS

Compliance with IEC 62271-200 to perform safer.

MILE is designed to meet the LSC2B-PM AFLR 31,5kA 1s classification as per IEC 62271-200.
The design is fully type tested to IEC 62271-200. The following type tests have been successfully passed:

• Short time and peak withstand current on primary circuits
• Short time and peak withstand current on earthing circuits
• Temperature rise and main circuit impedance
• Dielectric test on main and auxiliary circuits
• Making and breaking capacity of the circuit breaker within the panel
• Earthing switch making capacity
• Mechanical operations
• IP code
• Internal arc fault (IAC classified: AFLR, 31.5kA/1s)

Exceptional safety

In addition to IEC 62271-200 requirements, the application of a VCB with MAGNETIC ACTUATORS in MILE provides unique and unrivalled safety features such as remote and safe manual closing of VCB with a palm-held manual generator and the fastest arc fault interruption in less than one cycle.

High operational reliability

• The robust enclosure, made of 2mm corrosive resistant hot-dip galvanised metal sheets with reinforced doors and a safety labyrinth allows fast and simple erection.
• A rivet nut design provides not only rigidity of construction but also an opportunity to replace metal parts on-site without the use of special tools.
• An emergency trip push-button is located in the center of the panel. It has a striking, protruding design protected against accidental operation. The trip button can be quickly located in an emergency.
• Large and clearly visible mechanical position indicators located in view of an operator allows for positive operating status identification of the draw-out unit, VCB and earthing switch. Each mechanical indicator changes its status so that it exactly reflects/corresponds to the status of the switching device. Mechanical position indicators are duplicated by electrical auxiliary contacts to provide electrical signals into secondary circuits.
• Lockable access to the VCB racking in/out mechanism by a metallic shutter prevents unauthorised operations and interlocks the VCB in the trip position prior to racking a draw-out unit.
• An LV plug interlock visually prompts an operator to connect the draw-out unit to secondary circuits before the compartment door is closed.
• Accessories, such as door hinges, handlebars, locks and electrical indicators and buttons withstand thousands of operations and guarantee the appearance of a quality
• Minimal service checks on site and MILE is designed for a service life of at least 30 years. The VCB, earthing switch and cast resin insulation technology is considered virtually maintenance-free, so the maintenance requirements are only related to periodical checks to ensure the system operates correctly.

Greater Application Versatility

• Common design platform for 12, 17,5 and 24kV panels.
• Cassette and truck versions are available.
• Front or Front and Rear accessibility to the cable compartment
• Two sets of CTs and VT cassette placed in VCB or cable compartments.
• Panel width can be 600, 750 or 1000mm.
