Magnetic 3TF Series 3P AC Contactor 24V 120V 240V 480V 220V 3TF52

Magnetic 3TF Series 3P AC contactor 24V 120V 240V 480V 220V 3TF52

Applications:
3TF power contactors are suitable for switching and controlling squirrel cage and slip-ring motors as well as other AC loads,
such as solenoids, capacitors, lighting loads, heating loads and transformer loads.

Standards:
Contactors conform to IS/IEC 60947-4-1. They also carry the CE mark.

Coordinated feeder:
Contactors and bi-relays have been tested for type-2 coordination at Iq = 50kA, 415V AC, 50Hz as per IS/IEC 60947-4-1, for both
fuse protected as well as fuseless motor feeders.

Main parameters and Technical Performance:

Working and Installation Condition:

♦ Ambient air temperature: -5℃--+40℃ and average not more than +35℃ within 24 hours;

♦ Altitude: ≤ 2000m;

♦ Air condition: when the highest temperature is +40℃, the air relative humidity is not up to 50%, but the higher humidity is allowed at lower temperature. Like, 90% humidity at 20℃. The condensate dew should be considered when at lower temperature;

♦ Pollution degree: Class 3

♦ Installation category:III

♦ Protection degree: IP20

♦ Installation condition: the gradient angle between installation side and vertical side should not be more than ±5℃

♦ Impact and vibrattion: the contactor must be installed and operate under the circumstances of no obvious shaking, impact and vibration.
