Description
Order No.: 3TK15420AP0 3TK1542-0AP0 Contactor, AC-1, 4-pole, 800 A, main contacts 4 NO, Auxiliary contacts 2 NO + 2 NC, AC operation 220…230 V AC 50 Hz/240 V AC 60 Hz
Overview Standards
IEC/EN 60947‑1, IEC/EN 60947‑4‑1, IEC/EN 60947‑5‑1 (auxiliary switches)
The contactors also comply with the requirements of NFC 63‑110 and NFC 20‑040.
The contactors are suitable for use in any climate. They are finger-safe according to IEC 60529. Terminal covers may have to be fitted onto the connecting bars, depending on the configuration with other devices.
The contactors are used mainly for resistive loads (AC-1 and p.f > 0.95). They are also suitable for switching mixed loads in distribution systems (e. g. for supplying heaters, lamps, motors, PC power supply units) with p.f. > 0.8 according to IEC 60947‑4‑1; test conditions for utilization category AC‑1.
Control circuit
The solenoid coils of the 3TK10 to 3TK13 contactors (operating current up to 350 A) are designed as plug-in coils.
Surge suppression
The solenoid coils of the 3TK1 contactors can be connected at a later stage with RC elements, see Accessories and Spare Parts for 3TK1 Contactors.
