B-T21 AC200V 3B

MS-N Series Main Circuit B Contact Type AC Operation Type Electromagnetic Contactor Features

  • External dimensions and mounting surface area are greatly decreased compared to the conventional product, making for a small size and saving space.
  • Uses AC operation DC excitation method electromagnet.
  • Fully prevents noise.
  • Wide shared rated coil (nominal 200 V AC: rated 200 to 240 V AC 50/60 Hz).
  • Built-in surge absorbing function.
  • Greatly reduced power consumption.
  • Can be used with live part protection cover UN-CV / CZ□ type.
  • Twin contacts with high contact reliability are used as the auxiliary contact, and are applicable to a 20 V 5 mA load.
  • The material name used is displayed on major plastic parts, improving environmental compliance.
  • Main circuit inter-phase barrier is standard equipment, which improves safety.

  • Note 1: The table above indicates the guideline values of characteristics when using a 200 V AC coil during AC operation (B-N□), and when using 100 V DC during DC operation (BD-N□).
  • Note 2: Operating voltage is 20°C cold state, for both AC operation (at 60 Hz) and DC operation. For coils other than 200 V AC and 100 V DC, purchase approximately proportional to the voltage.
  • Note 3: Input and power consumption are shown as average values. Stays nearly the same even when using coils other than 200 V AC or 100 V DC.
  • Note 4: Coil current is the average value when applying 220 V 60 Hz during AC operation, and when applying 100 V DC. When using a coil other than the 200 V AC coil, divide the constant input by the coil voltage to find the coil. When using a coil other than the 100 V DC coil, divide the power consumption by the coil voltage.
  • Note 5: Operating time is the value when applying 220 V 60 Hz during AC operation, and 100 V DC during DC operation. Stays nearly the same even when using coils other than 200 V AC or 100 V DC.
