Available from Eaton Bill Switchgear is a range of air circuit-breakers (ACBs) that enable electrical contractors and panel builders to design and build switchboards fed from standard 1MVA utility transformers or other supplies up to 2000A:
This range is part of the Eaton Bill Switchgear Talisman MPS modular panelboard system which enables contractors to assemble panels, that would normally be factory-built, using parts available on a short lead-time through Eaton Bill Premier stockists.
These ACB modules extend the maximum rating of Talisman MPS from 1250A to 2000A and widen the choice of incomer to include ACBs, fused combination switches, moulded-case circuit-breakers or direct cable connection. Mechanically-interlocked dual incomer options are also available for use with mains and standby supplies.
The three- and four-pole drawout-type ACBs are available in 800A, 1000A, 1250A, 1600A and 2000A ratings in Forms of Separation up to Form 4 Type 2.
A range of benefits:
Talisman MPS is a modular system that enables the construction of a wide range of panels, from a simple panelboard with one incoming module and one outgoing module, to a composite switchboard with any number of outgoing modules. The system offers the freedom to use fuse or circuit-breaker technology on the incoming and outgoing sections to meet the needs of discrimination, fault level or speed of operation. A dedicated software program allows panels to be designed simply and quickly.
The range of outgoing modules includes FCS and MCCB modules up to 12 ways or 800A per module. Ancilliary modules are also available for up to 24 SPN or TPN miniature circuit-breakers or RCBOs.
While Talisman MPS is ideal for contractor-built systems, panels can also be supplied as compact, cost-effective factory-built assemblies. The concept offers the potential for a basic Talisman MPS panelboard to be extended at a later date.
A design programme with advantages:
The Talisman MPS Advantage design program has been upgraded to include the new ACB modules. The software, which is designed to be run on a normal PC, leads the user through a ten-stage design process ensuring that all the necessary elements are included. These include metering facilities, current transformers and spare modules as well as basic incoming modules, busbars, outgoing modules and cableways. It produces a drawing of the finished panel together with a parts list, dimensions, weights and prices.
Eaton Bill Switchgear's sales engineers can work with the contractor to produce a design or, depending his resources and needs, the contractor can use the software himself.
Talisman MPS is based on a series of 750mm wide by 250mm deep enclosures. Modules are designed for top, bottom or side cable entry. Busbars are tin-plated copper, to withstand humid conditions. Short-circuit ratings of up to 50kA for 1 second match many standard switchboard specifications. The system is designed to BS EN 60439-1
