Series 5000
Load Break Switches
UL - 98B/IEC
Load Break Switches for Solar Power Applications
The Electroswitch Series 5000 “Load Break Switches”
meet the stringent safety requirements found in solar
power disconnect switch applications.
A fast transfer mechanism combined with self cleaning
knife-type contacts assures safe, reliable switching.
Tested in accordance with UL 98B and IEC, the Series 5000
provides excellent load carrying, switching and dielectricperformance.
