Busbar

The Loadbank 125 panel boards have ASTA certified busbars with a short circuit rating of 25kA for 1 second for the 250A boards and 2SkA for 3 seconds for the 400A boards.

Outgoing Ways

The 250A panel boards are available in 6, 8 or 12 triple-pole outgoing ways and the 400A boards are available in 6, 8, 12 or 16 triple-pole outgoing ways offering great flexibility in design.

Modular Construction

This range has a common width and depth for the panel board and all add-on enclosures thereby ensuring ease in panel building applications.

Add-on Enclosures

Panel building options for the Loadbank 125 range include; cable spreader box for additional cabling room, metering housing for incoming and outgoing DIN-rail meters, service center and additional enclosure to house one Loadline YM3 or YS3 MCCB up to 250A as an outgoing device.

Form

The 250A & 400A panel board meet the requirements of Form 2 construction as standard.

Outgoing Devices

Both the 250A and the 400A panel boards are designed to accept Loadline YM2 frame MCC3. These devices are fixed MCCBs available in ratings 16A to 125A at 37kA. YM2 MCCB range is complimented by a wide range of accessories including; shunt trips, auxiliaries and UVRs.

Surge Protection

A Type II Class II surge protection device can be internally installed in the Loadbank 125 panel boards. This device comes with a remote indicator panel which fits in a knockout in the front shield for easy surge protection monitoring. A Type I Class I device can also be used with this range via installation in a service center.

Incoming Options

The Loadbank 125 panel boards have a variety of incoming options including; MCCB and switch disconnector.

Metering

By using the add-on metering enclosures this panel board system can be easily metered for incoming and outgoing circuits. The add-on metering enclosure can also house the current transformers.

The Loadbank 250 modular enclosure system is engineered to provide unrivalled flexibility and build simplicity needed in order to produce a wide range of power distribution solutions. It consists of TP&N busbars of 400A and 800A with three different sizes of 6, 12 or 18 outgoing ways.


This range houses the incoming and outgoing devices in separate adjoining enclosures which allows the widest range of circuit permutations, including oversized outgoing circuits, which can all be accommodated within a common format.


Incoming options range from 160A to 800A MCCB or Switch Disconnector depending on the board. There is a single frame size MCCB for outgoing devices which is the YS3 frame MCCB up to 250A.

Material Specification

The panel boards and enclosures are formed from 1.2-1.6 mm sheet steel. The busbars are tin plated formed from hard drawn high conductivity copper, grade CIOI, ETP. Standard finish is epoxy powder coating in light grey RAL 7035, thickness 50-75 microns.
