Siemens SP4411 Meter Stack

Siemens SP4411 Meter Stack is a 400-amp, 120/240-volt, single-phase meter center configured as a four-gang Uni-PAK meter pack. It provides four meter sockets rated at 125 A each in a ring-type arrangement with four jaws, enabling four independent tenant meters within one enclosure. Designed for top or bottom feed, this SP4411 unit supports 120/240 V single-phase, 3-wire service and uses a 400 A bus to carry the overall load. It is part of Siemens' WP Uni-PAK family and is UL 67 listed for electrical service installations. Typical applications include multi-tenant residential buildings or small commercial properties where four separate meters are required in a compact, integrated metering solution.
