Soft Start Cabinet

Soft start cabinets integrate a motor soft starter, protection devices, and control components in a pre-wired, ready-to-install enclosure — available as online, integrated bypass, or combination soft starter configurations. Designed for 3-phase motors from 5.5kW to 1000kW, these enclosed soft starter panels eliminate the need for separate wiring and component sourcing, reducing installation time and ensuring reliable motor startup, protection, and monitoring in a single unit.

Standard configuration uses an online soft starter with full motor protection. Bypass and built-in contactor versions available on request. Complete low voltage soft starter packages with enclosure, protection devices, and control wiring available for OEM and project requirements.

Key Features

  • Pre-wired and ready to install — all components factory-assembled and tested, reducing on-site installation time and wiring errors
  • Smooth start and stop — reduces inrush current and mechanical shock on motors, pumps, fans, and conveyor systems
  • Comprehensive motor protection — overload, overcurrent, overvoltage, undervoltage, phase failure, and overheat protection built in
  • RS-485 communication — supports remote monitoring and integration with SCADA and PLC systems
  • Enclosed industrial cabinet — standard cold-rolled steel (IP20), stainless steel and wall-mount versions available on request
  • Custom configurations — power rating, voltage, bypass option, enclosure grade, and branding customizable for OEM and project requirements

Applications

Suitable for water pumps and booster systems, fans and blowers, conveyor systems and heavy machinery, water treatment and sewage systems, HVAC systems, and mining and industrial equipment.
