Product Description

- Core Power Continuity
The Automatic Transfer Switch guarantees uninterrupted power by switching between two sources (e.g., mains/generator) during outages. Ideal for critical settings like data centers and hospitals, its 3-phase (3P) design and 110V AC rating suit low-voltage, high-reliability needs. - Rapid Automatic Switching
A built-in controller monitors voltages, triggering transfers in ≤100ms during failures. Its "break-before-make" mechanism prevents short circuits, with adjustable time delays for compatible load management. - Enhanced Isolation Safety
Key isolation features include a visible locked-off position for maintenance and mechanical interlocks to avoid simultaneous source activation, meeting strict safety standards. - Robust Specifications
Rated for 125A continuous current and 110V AC, it handles 50/60Hz and 50kA short circuits (with external protection). Compact, IP54-rated, it includes LED indicators and manual override. - Versatile Compliance
Certified to IEC/UL 62368-1, it excels in backup systems for telecom, healthcare, and industry-blending speed, safety, and reliability for mission-critical use.
