Note: ReliaMod™ meter stacks are designed to accept only certain tenant breaker frames based on their kAIC. There are meter stacks that only accept 10-22 kAIC tenant breakers and different meter stacks that only accept 42-100 kAIC tenant breakers. These tenant breakers are not interchangeable between different designs of stacks. Please be sure you are selecting the correct meter stack type based on the kAIC of tenant breaker you are using as well as the available series ratings in DET008. The modular metering configurator in ABB empower can help assist in the correct product selection. Note: XT3 and XT4 tenant breakers listed as 2-pole for 1-phase applications are 3-pole case breakers suitable and UL Approved for 1-phase applications with load lugs factory installed on the two outside poles. Note: All XT3 and XT4 tenant breakers for ReliaMod™ 225A socket meter stacks come with thermal magnetic fixed (TMF) trip units. All factory installed XT5 tenant breakers for ReliaMod™ 400A meter stacks come with thermal magnetic adjustable (TMA) trip units.
