Magnetic Contactors DU-N Series (Part Numbers)

MS-N Series AC Operation Electromagnetic Contactor For Direct Current 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 reduces power consumption (DU-N30: 2.2 W, DU-N120: 2.9 W).
• Conforms to finger protection. Compatible with live part protection cover unit UN-CZ□ type, used for the MS-N series.
• Twin contacts with high contact reliability are used as the auxiliary contact, and are compatible with 20 V DC 5 mA.
• Compatible with auxiliary power contactor UN-AX□ type, used for the MS-N series.
• The material name used is displayed on major plastic parts, improving environmental compliance.
• Uses thermoplastic resin around terminals, enhancing the strength of plastic parts.

MS-N Series AC Operation Electromagnetic Contactor For Direct Current Specifications

Rating

• Note 1: The role of the a-contact for variable motor control is double-loading / non-voltage closing, and the role of the b-contact for dynamic brake contact is 1 × loading / non-voltage closing.
• Note 2: A common DC motor is compatible with motor load for DC2 class (shunt motor start/stop) and DC4 class (series-wound motor start/stop) from JEM1038.
• Note 3: The *1 allowed energization time is 30 seconds. When using for inching, use the rated operating current for common DC motors.

Performance

Note 1. *1 time constant L/R = 15 ms, break count 25 times.

Characteristics

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