STP Industrial Motor Starter & Control Panel

Safeguarding Your Motors, Optimizing Your Operations.

The STP Starter Panel is a high-performance, durable electrical control solution designed to provide reliable starting, stopping, and comprehensive protection for 3-phase AC motors. Built with industrial-grade components and housed in a rugged enclosure, it offers unparalleled safety, efficiency, and ease of maintenance for critical motor-driven equipment across various sectors.

Key Features & Benefits

• Robust Enclosure:
  • Construction: Heavy-gauge steel (or specified material like ABS/Polycarbonate for certain ratings), powder-coated for superior corrosion resistance and durability.
  • Environmental Protection: Available in NEMA 1, 3R, 4, 4X, and 12 ratings (or equivalent IP ratings like IP65, IP66) to suit diverse indoor and outdoor environments, protecting against dust, water, and corrosion.
  • Mounting: Designed for easy wall-mounting or stand-alone installation, ensuring flexible deployment.
• Direct-On-Line (DOL) Starting:
  • Reliable Operation: Utilizes high-quality, long-life contactors for efficient and dependable direct-on-line starting of motors.
  • Simplicity: Straightforward and cost-effective starting method suitable for applications where high inrush current is permissible.
• Comprehensive Motor Protection:
  • Overload Protection: Integrated thermal overload relays (or electronic overload relays) provide precise and adjustable protection against sustained overcurrents, preventing motor damage due to overheating.
  • Short Circuit Protection: High-rupturing capacity (HRC) fuses or Miniature Circuit Breakers (MCBs)/Molded Case Circuit Breakers (MCCBs) ensure immediate disconnection in case of short circuits, protecting both the motor and the electrical system.
  • Single Phasing Protection (Optional/Integrated): Detects and trips the motor if one phase is lost, preventing severe damage to the motor windings.
  • Phase Reversal Protection (Optional): Prevents motor operation in the wrong direction due to incorrect phase sequencing.
  • Under/Over Voltage Protection (Optional): Safeguards the motor from erratic supply voltage fluctuations.
• Intuitive Control Interface:
  • Start/Stop Push Buttons: Robust, clearly labeled industrial-grade push buttons for manual control.
  • Selector Switch (Auto/Manual/Off - Optional): Allows for flexible operation modes, enabling remote control or integration with building management systems (BMS).
  • Emergency Stop Button: Latching-type E-stop button ensures immediate and safe shutdown in critical situations, enhancing operator safety.
  • Indicator Lamps: Bright, long-life LED indicators for:
    • Power ON: Confirms panel is energized.
    • Motor RUN: Indicates motor is operating.
    • Motor TRIP: Alerts operators to a fault condition (e.g., overload).
• High-Quality Components:
  • Utilizes reputable brands for contactors, overloads, MCBs/MCCBs, and control components, ensuring reliability and extended service life.
  • All internal wiring is neatly routed, properly terminated, and clearly labeled for ease of troubleshooting and maintenance.
• Ease of Installation & Maintenance:
  • Spacious internal layout with ample wiring space simplifies installation and future servicing.
  • Clearly marked terminal blocks for quick and error-free power and control wiring connections.
  • Hinged door with robust latches (and optional lockable mechanism) provides secure access to internal components.
