Electric Singles Phase 3 Phase Magnetic Starters AC Contactor DOL Motor Starter

Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Motor Control: A Direct On-Line (DOL) starter designed to safely start and stop single-phase and three-phase AC motors (up to 690V) with bimetallic overload protection technology.
  • Protection Mechanisms: Integrates under voltage, overload, overvoltage, phase loss, and short circuit protection to ensure reliable motor operation and safety.

Key features

  • 1. Corrosion-Resistant Material Technology

    • With a durable metal body (steel/aluminum) and bimetallic thermal overload protection, this DOL starter ensures long-term reliability in industrial environments. The corrosion-resistant design outperforms plastic-based starters, maintaining performance in harsh conditions.

  • 2. Intuitive Interactive Design

    • With clearly labeled green "Start" and red "Stop" buttons, operators achieve instant motor control. The raised front panel protects controls from accidental contact, reducing downtime compared to flat-panel designs.

  • 3. Robust Performance Parameters

    • With a wide power range up to 690V AC and 50Hz compatibility, this starter handles heavy-duty motors. Its multi-layer protection (under/over voltage, overload, phase loss, short circuit) ensures 99.9% uptime—superior to basic starters lacking full protection suites.

  • 4. Versatile Scenario Solutions

    • Designed for continuous industrial use, this DOL starter supports uninterrupted motor operation in factories, pumps, and HVAC systems. Its compact size enables easy integration into existing machinery, unlike bulkier competitors.

  • 5. Comprehensive Certification Standards

    • With EPR Germany Packing, RoHS compliance, and CE/IEC certifications, this starter meets EU and global safety regulations. This ensures eco-friendly disposal and reduced electromagnetic interference compared to non-certified alternatives.

Supplier's note

  1. Key Technical Breakthroughs:

    • Bimetallic Overload Protection: Ensures precise thermal monitoring for prolonged motor lifespan.
    • 690V Capacity: 30% higher than industry benchmarks, enabling use in high-power industrial setups.
    • Multi-Protection Suite: Combines five safeguards (under/over voltage, phase loss, etc.) for unmatched fault resilience.

  2. Version Selection Guidance:

    • Base Model: Ideal for small workshops or low-voltage applications (e.g., residential pumps).
    • Advanced Model: Suitable for medium-scale operations (e.g., commercial HVAC systems) needing phase loss protection.
    • Pro Model: Best for heavy industries (e.g., mining, manufacturing) requiring full protection and 690V compatibility.

With its 690V capacity, the Pro version handles high-power motors with ease, while bimetallic tech ensures reliability even in harsh conditions. Pair this with customizable I/O for seamless integration into smart factories.
