New dc switch-disconnectors handle the most demanding PV applications
01 August 2015
Eaton's Dumeco dc switch-disconnectors help solar PV equipment manufacturers and installers gain a competitive edge in the solar power market.
The products are available in four frame sizes, the largest with 800A, 1,000A and 1,250A options, and the smallest offering 63A, 80A and 100A versions. This covers applications ranging from residential and light commercial rooftop sites to large commercial and utility scale installations, as well as solar combiner box and inverter equipment.
This switchgear is available in 2-pole configurations that reduce the need for bridging links between the poles, cutting installation time and copper costs, while the bi-directional pole connection gives the installation flexibility. Features include a small footprint and an independent, manually operated mechanism to control the self-cleaning roller contacts.
Operation is either via a direct handle or an extension shaft of up to 600mm plus handle for door interlocking. IP65-rated grey or red/yellow K-Line handles are available, with both padlock and cylinder lock versions. Door interlocking configurations include a ‘defeatable’ option in the ON position for fault finding. An auxiliary switch set is also available offering 1NO+1NC contacts.
The Dumeco DC switch-disconnectors are rated to 1,000Vdc, and are compliant with standard EN-IEC 60947-3 and have CE, CCC, RoHS and EAC certifications. They offer high short-circuit ratings and operate to utilisation category DC-21B. The units are suitable for base plate mounting.
