ABB Offers Solar Industry Molded Case 1000VDC Breakers, Switches for UL489B Compliance, Easier Installation


ABB presents a full line of molded case circuit breakers (MCCB) and molded case switches (MCS) that meet the new UL489B 1000 volt DC standard using a compact, three-pole design, to allow for easier and quicker installation for inverter and combiner box manufacturers.



San Francisco – ABB, the solar industry's leading power technology provider, is presenting its molded case solution for 1000VDC at the Intersolar North America conference and exhibition this week.



ABB has created this full line of molded case circuit breakers (MCCB) and molded case switches (MCS) that meet the new UL489B 1000 volt DC standard in the popular sizes up to 400 amps by using a three-pole design exclusive to the industry. The smaller footprint and fewer poles allow for quicker and easier installation due to size, and fewer poles are required to connect in series. To increase the ease of installation, ABB also includes the line to line jumpers standard for 2+1 or all poles in series applications. This also reduces the level of possible loose connections and terminations.



With adjustable breaking capacities up to 800 amps, the product line is rounded out by also offering molded case switches up to 1000 amps using common frame sizes and accessories as the standard Tmax product family.

 

"The Tmax PV family is an efficient and effective solution for any inverter or combiner box manufacturer wishing to reach 1000VDC with their equipment," said Thomas Leja, product manager of MCCB's at ABB. "Being able to use the same footprint and accessories for breaking or switching applications is a great advantage for engineers to save time and money in their designs."
