Built-in Soft Starter

Built-in soft starters integrate the bypass contactor directly into the unit — no external contactor required, no additional wiring. Switches to direct AC operation after startup, reducing SCR heat and extending component life.

Designed for OEM and compact panel applications where space and wiring simplicity are critical. Available from 5.5kW to 320kW.

Built-in protection includes overload, under-voltage, phase failure, overheat, and short-circuit. RS485 Modbus supported for remote monitoring and PLC/SCADA integration.

Key Features

  • Integrated bypass contactor — no external contactor or additional wiring required
  • Smooth start and soft stop — adjustable start time 0–30s
  • LCD display with keypad — parameter setting and status monitoring on-unit
  • Compact design — ideal for OEM panel and space-limited installations
  • Full motor protection — overload, phase failure, overheat, short-circuit
  • RS485 Modbus — remote monitoring and PLC/SCADA integration
  • Wide voltage range — 220V / 380V / 440V / 480V / 660V / 690V
  • Power range — 5.5kW to 320kW

Applications

Suitable for pumps, fans, compressors, and continuous-running industrial machinery where compact installation and reduced wiring are essential. Ideal for OEM motor control panel integration.
