Product Overview

Meet the RQG MZJ-400A, a robust 36V DC solenoid contactor engineered to handle demanding electrical loads with reliability. This heavy-duty device is designed to energize and hold power for control circuits in electric vehicles and industrial machinery, offering a practical blend of strength and precision for challenging environments.

Key specifications

  • Coil rated voltage: 36V DC
  • Load current: 400A (continuous, DC-1)
  • Max contact circuit voltage: 80V DC under 100A load
  • Coil power: 120W–170W (pull-in); 5W–11W (holding)
  • Action time (pull-in): ≤ 25 ms
  • Release time: ≤ 10 ms
  • Electrical life: 20,000 cycles; Mechanical life: 300,000 cycles
  • Contact material: Silver alloy (AgCdO)
  • Load terminals: M10 studs; Coil terminals: M4 studs
  • Insulation resistance: 20 MΩ; Dielectric strength: 1000 VAC (1 minute)
  • Operating temperature: -25°C to +70°C; Protection: IP40

Direct replacement and installation

This unit is a direct replacement for the MZJ-400A, ideal for upgrades or repairs in heavy-duty golf carts, electric forklifts, marine winches, telecom equipment, and uninterruptible power supplies. Professional installation is highly recommended to ensure proper wiring and coil control.

Durability and performance in real-world use

The silver alloy contacts deliver dependable conductivity, while the continuous duty design helps maintain engagement without overheating. A wide operating temperature range and IP40 protection mean the contactor is prepared for vibration, shock, and varied working conditions commonly found in mobile or industrial setups.

Important installation note

This is an intermittent-duty coil design. The control circuit must provide high starting power (120W–170W) for pull-in, then reduce to low holding power (5W–11W). Without a holding circuit, coil life may be affected. Professional wiring is advised.
