Specifically, ABB supplied power distribution cabinets, Uninterrupted Power Supply (UPS) cabinets, and power counters. One requirement was that the protection Miniature Circuit Breakers (MCB) should be hot pluggable and adjustable for phases.
"We were able to offer the whole solution with outstanding technology and convenience service," says Cheney-ZhaoZhen Chen, ABB's Product Group Marketing Manager for Enclosures & DIN Rail products in China. "Especially, the solution of SMISSLINE busbar and adaptor with S200 MCB met China Post’s requirement of hot plugability and also saves costs for the power counters."
In addition, the auxillary contactors installed at the bottom of the MCBs for status detection helps save a significant amount of space in the cabinets. Besides S200 MCB and SMISSLINE, ABB also provided all other low voltage components such as Tmax breakers, OVR surge protection devices, the monitoring system (EM-PDU) with a touch screen, which displays all electric parameters and controls of the power cabinet.
