— ReliaMod™ Meter stack families and their tenant breakers

ReliaMod™ meter stacks are designed to accept certain frames of tenant breakers based on the tenant breaker kAIC being used. For example: • A ringless 125A socket 6-gang meter stack that is series rated at 65 kAIC to a 1200A XT7 MCB will allow the use of 10 kAIC THQL tenant breakers, which would be a meter stack order code number of RMS28612 L RLR • That same ringless 125A socket 6-gang meter stack fully rated at 65 kAIC would utilize TEY tenant breakers, which would be a slightly different meter stack order code number RMS28612 H RLR

This feature allows ABB meter stacks to be much more flexible in design based on the specific kAIC of the application. It is always important to understand your application up front with the specific kAIC needed and what combinations of breakers can be series rated per ABB publication DET-008 in order to select the appropriate meter stacks and tenant breakers for them. The modular metering configurator in ABB empower can help assist in the correct product selection. Please see the ReliaMod™ meter stack family summary below along with the specific tenant breakers they can accept.
