Energing Saving Double Coil DC Contactor / Solenoid

Model: MZJ-400S, 400A, normal open, single pole single throw (NO SPST)

Circuit Diagram

Overview

The MZJ-400S contactor is a SPST (Single Pole Single Throw; normally open type) DC contactor, designed for direct current loads, particularly for motors on small electric vehicles such as light industrial trucks, electric forklift, electric pallet stacker, golf cart, etc. MZJ-400S has double breaking main contacts with silver alloy contact tips, which are weld resistant, hard wearing and have excellent conductivity.

Specifications:

• Model: MZJ-400S (double-coil, close contact chamber)
• Control coil voltage options (Volts): 12V, 24V, 30V, 36V, 40V, 48V or 60V
• Main rated load current of contact circuit (amps): 400A
• Dielectric (volt) strength: 50Hz 1000V AC 1min
• Current volt drop of main contact at 400A: Not above 80mV
• Mounting: two 6.5 mm fixing holes in bracket; pitch-row: 63 mm
• Main contact full load rating voltage (recommended):
  • Inductive load: max. 48V DC
  • Resistive load: max. 60V DC
• Mechanical life: 100,000 times
• Electric life: 2,000,000 times
• Ambient temperature：-25 ~ +40°C
• Altitude range：0 ~ 2000m
• Max.relative humidity: 90% at 25°C
• Installation method：vertically or horizontally
• Voltage fluctuating：0.7 ~ 1.1Ue
• Net weight: 0.80 kg

MZJ-400S is a contactor of double-coil winding, with closed contact chamber. The main contacts are pulled to close by the starting coil L1; then the holding coil L2 keep the contactor in closing status with smaller current. With its double-coil design, MZJ-400S works with a smaller holding current which permits a much lower heat dissipating and thus can save upto 90% of energy than the signle-coil contactor of same rates of working voltage and working current.
