■ Overview
Version
The 3TG10 power relays/miniature contactors with 4 main con-
tacts are available with screw terminals or 6.3 mm × 0.8 mm flat
connectors. The versions with screw terminals are climate-proof
and finger-safe according to EN 61140.
The 3TG10 miniature contactors are characterized by their width
of only 36 mm.
Surge suppression
The 3TG10 power relays/miniature contactors have an inte-
grated 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.
AC and DC operation
EN 60947-1, EN 60947-4-1, EN 60947-5-1
Overload and short-circuit protection
The 3UA7 overload relay can be used for overload protection.
This applies to mounting onto contactors and to stand-alone
installation.
■ Technical specifications

If the three main current paths carry a load of 20 A, the following applies if
I > 10 A in the fourth conducting path: Permissible ambient temperature
40 °C.
