Overview
Standards
IEC 60947-1, IEC 60947-4-1, IEC 60947-5-1
Version
The 3TG10 power relays/miniature contactors are available
with screw terminals or 6.3 mm × 0.8 mm flat connectors.
The versions with screw terminals are suitable for use in any
climate and finger-safe according to IEC 60529.
The 3TG10 miniature contactors are characterized by their width
of just 36 mm.
Surge suppression
The 3TG10 power relays/miniature contactors have an
integrated protective circuit against opening surges.
■
Application
Because they are hum-free they are suitable for use in house-
hold appliances and distribution boards in office and residential
areas.
They can also be used for applications where there is little space
such as air conditioners, heating systems, pumps and fans, i.e.
for simple electrical controls.
