Arcing contacts
• Defined arc initiation and positioning
prevents erosion of contact surfaces
• Minimized arcing time

Linear contact system
• Provides optimum contact
• Achieves low power los

Short-circuit pinch stop
• Prevents pinch effect when making on
a short-circuit fault
• Enables short-circuit withstand currents
up to 110 kA

Application
• The GAMMA contact system offers an
optimum performance profile for size
1 and 2 devices to be installed in
power utility networks
• The DELTA contact system, having
continuous current carrying capability
up to 1000 A, provides excellent loadbreak
capability in industrial applications
and in switching devices
having rated currents above 400 A
