Miniature contactor Flat connector terminal 3 NO and 1 NC 3TK2031-3AN2

Overview Standards

IEC/EN 60947‑1, IEC/EN 60947‑4‑1

The 3TK20 miniature contactors are suitable for use in any climate. The miniature contactors with screw terminals are finger-safe according to IEC 60529.

Connection method

The miniature contactors are available in versions with screw terminals, 6.3 mm plug-in terminals and solder pin connections for soldering to printed circuit boards.

The 3TK2 contactors with 6.3 mm x 0.8 mm flat connectors are coded and can be used in the plug-in base with solder pin connections for printed circuit boards (see Accessories for 3TF, 3TG, 3TK Miniature Contactors).

Ratings of three-phase motors

The quoted rating (in kW) refers to the output power on the motor shaft (according to the nameplate).

The power rating specifications of the contactors in kW are guide values for 4-pole standard motors at 50 Hz AC and specified voltage (e.g. 400 V). The actual starting and rated data of the motor to be switched must be considered when selecting the units.

Application

Contactors with plug-in terminals
The main area of application for the 3TK20 miniature contactors with flat connectors is in household equipment. These contactors are also suitable for simple electric controllers.

No auxiliary switch blocks can be retrofitted.
