3 Phase Automatic Changeover Switch Automatic Transfer Switch

Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Automatic Power Transition: Seamlessly switches between primary and backup power sources (e.g., grid and generator) to ensure uninterrupted power supply for critical loads.
  • Manual Override: Features a safety-protected manual switch (red cover) for testing, maintenance, or forced power source selection.
  • 3-Phase Compatibility: 4-pole configuration supports three-phase systems (L1, L2, L3, N) with a max voltage of 400V and 63A current rating, ideal for high-demand applications.

Key features

  • 1. Durable Material Technology for Enhanced Safety

    • With a corrosion-resistant plastic housing, ensure reliable insulation and resistance to electrical stresses, enhancing safety compared to metal-bodied switches in corrosive environments*.

  • 2. Dual Manual-Automatic Operation for Flexible Control

    • With a dual manual-automatic operation mode, switch seamlessly between power sources manually for testing or automatically during outages, offering greater control than fully automatic models*.

  • 3. High-Performance for Heavy-Duty Applications

    • With a 63 A current rating and 400 V compatibility, handle heavy industrial loads up to 20% higher than standard residential transfer switches*, ensuring reliability for commercial and industrial use.

  • 4. 4-Pole 3-Phase Design for Uninterrupted Critical Power

    • With a 4-pole 3-phase configuration, maintain uninterrupted power for critical equipment in commercial settings, reducing downtime by 30% versus basic single-phase transfer switches*.

  • 5. Safety-Certified Design for Regulated Industries

    • With compliance to IEC/UL safety standards, ensure regulatory compliance in healthcare and manufacturing environments, unlike uncertified alternatives*.

Supplier's note

  1. Three Technical Breakthroughs:

    • Manual Override Redesign: The safety interlock (red cover) prevents accidental switching, reducing human error by 40%.
    • 4-Pole Configuration: Enables seamless three-phase power transfer, critical for industrial machinery.
    • Faster Switching Speed: The Pro Model’s 30 ms response time ensures power continuity even in milliseconds-long outages.

  2. Optimal Version Selection:

    • Base Model: Ideal for small commercial setups (e.g., retail stores) requiring 63 A and standard IEC certifications.
    • Advanced Model: Best for medium-scale industries needing higher voltage (up to 440 V) and 20% faster switching.
    • Pro Model: Designed for heavy industrial use (e.g., factories, data centers) with triple the safety certifications and 81.8 A capacity.

With the Pro Model’s 30 ms switching speed, you can maintain power to critical equipment during brief outages. With its UL 1008 certification, it also meets stringent safety standards for global deployments. Pair the Advanced Model’s expanded voltage range with its faster switching to ensure reliability in fluctuating grid conditions.
