We have listened to you: new GroupStak developments

Download our leaflets for GroupStak

Following the recent successful roadshow we have taken on board customer feedback and have developed the GroupStak to include the following features:

Form 3b solution.

The GroupStak switchboard is now developed to include a form 3b option. This offers a higher stacking density at lower price than the standard form 4b version. Maximum number of feeders of different types are listed below:

  • 56 - single pole MCCBs, max 125A
  • 21 - 3 pole MCCBs, max 160A
  • 17 - 3 pole MCCBs, max 250A
  • 12 - 3 pole MCCBs, max 400/630A

Electronic feeders

GroupStak is now design verified with outgoing MCCBs with electronic protection.

TemBreak 2 MCCBs from 250A frame to 630A frame are available with electronic protection units. Current ratings, In, of 40A, 125A, 160A, 250A, 400A, 630A are available. These offer flexibility as their characteristics can be set between 0.4 and 0.1 times In.

Every TemBreak 2 electronic protection unit includes overload protection (L), delayed short-circuit protection (S) and instantenious protecion (I) as standard. Metering and CTs

Metering and CTs

GroupStak has now been developed to accept Rayleigh’s Easywire plug and play meters and CT's.

The steel work is pre-drilled for ease of mounting with pre-cut clear cover plates and door cuts-outs on request.

Spare ways

Many specifications request provision for future additions (spare ways). GroupStak can have spare ways included without MCCBs fitted. They have pre-coppered to the main bus bar making it a quick and easy job to add future MCCB outgoing devices.

We hear you!

We have asked registered users for their feedback on the TemCurve Lite software. Some people complained that it was difficult to download.

We have removed the registration form from TemCurve Lite download. You may now download it without registration.

Overall we received positive feedback with some good suggestions which we will take in to account.

For those of you who would like to receive Terasaki updates we have added a registration form on our news page. Subscribe and be the first to receive our news.

How to Select and Set Circuit Breakers for Generators

Generators differ from other electrical power sources in their ability to withstand electrical overloads and fault currents. These differences should be respected when selecting and setting circuit breakers which protect generators.

Terasaki have prepared a designed guide that explains the parameters of generators and circuit breakers which should be considered when selecting and setting circuit breakers which protect generators.
