Technical Data & Available Versions

TABULA is a unique low voltage switchboard system, fully tested and certified from international testing labs. From the standard modular parts of TABULA system, WESCOSA builds various assemblies, e.g. small distribution boards, Withdrawable MCC’s and heavy distribution boards for extreme current ratings.

Busbar System

 The busbar system complies with BS EN/IEC 60439 and consists of both vertically and horizontally mounted busbars. Vertical busbars are “C” shaped Cu-bars with current ratings 225A-1600A. Horizontal bars are standard shaped Cu-bars 250A – 7800A.

Vertical Distribution Busbars

 The vertical distribution busbars are designed as copper C-Profiles reducing the skin effect to a minimum. The profiles are stiff in order to withstand high short circuit levels and well suited from branching without drilling holes/connections by means of spring nuts.

Units (Compartments) (Din Rail) Units

 The great variation of DIN-rail material demands a flexible built-in system. DIN rail parts are in accordance with DIN 43 880, meaning that all ordinary components can be built-in as standard. This is e.g., MCCB’s, domestic fuses, earth-fault relays, motorstarters, etc.

Air Circuit Breaker (ACB) Units

 An ACB is often used as incoming short circuit protection from the current rating of 800 A and up. It comes in fixed and drawout versions, where the drawout versions can be removed from the main busbars without having to loosen any connection in the switchboard.

Draw-Out Units

 General Information

 Draw-out compartments are used in installations, where a production stop from longer time is unacceptable and where preventive maintenance is demanded.

Connected Position

 In connected position both main and sliding contacts are connected.

Test Position

 The push button is activated and the drawer is pulled out. The drawer will automatically lock in the test position, where the sliding contacts are still connected, to maintain the control current.
