Sejaede 110V 63A 2P Dual Power Automatic Transfer Switch — 2s transfer, auto/manual, overload protection

This compact transfer switch is built for locations that need fast, reliable switching between a primary and backup 110V supply. Designed to handle line currents from 6A up to 63A at 50/60Hz, the unit detects voltage loss or phase faults and moves loads in roughly two seconds. Its dual-mode operation (automatic and manual) and integrated protections make it a practical choice for residential systems, offices, and critical public spaces that require uninterrupted power to selected circuits.

How does the transfer switch detect and respond to a power failure?

The Sejaede switch continuously monitors voltage and phase status on both A-phase sources. When it identifies loss of voltage, phase loss, or unacceptable under-voltage on the active source, it initiates an automatic transfer to the alternate source, typically within about two seconds. Manual transfer is available for controlled switching or maintenance.

• Voltage monitoring across both input lines
• Automatic transfer on loss of voltage or phase failure
• Approximately 2 seconds conversion time
• Manual push-button override for operator control

What protections and safety features are included?

This model includes multiple protective functions to safeguard both the switch and connected loads. Built-in short-circuit and overload protection reduce risk to wiring and equipment, while under-voltage and loss-of-voltage detection prevent unstable supply conditions. For optimal safety, the manufacturer recommends feeding both main and backup supplies through dedicated circuit breakers.

• Short-circuit and overload detection
• Under-voltage and loss-of-voltage protection
• Phase loss detection to avoid improper connections
• Installation guidance and manual included

How easy is it to install and maintain this transfer switch?

The unit is designed for straightforward panel or surface mounting with standard hardware and clear dimensions. Installation dimensions are 128mm x 122mm with M6 mounting holes, and the switch ships with an instruction manual to guide wiring and setup. Routine maintenance is minimal—visual inspections and verifying breaker coordination are usually sufficient.

• Installation footprint: 128mm x 122mm (5.04in x 4.8in)
• M6 mounting hole diameter for secure attachment
• Suitable for panel or surface mounting in electrical enclosures
• Manual mode for testing and maintenance

Which applications and environments is this transfer switch best suited for?

The Sejaede 110V 63A 2P switch is aimed at locations where maintaining power to selected loads is essential. Typical deployments include residential backup power circuits, office systems, fire protection circuits in public buildings, and medical or administrative areas that cannot tolerate prolonged outages. Its compact size and broad current range make it adaptable across many installations.

• Residential backup circuits and critical appliances
• Office buildings and important administrative areas
• Fire protection and emergency systems in public spaces
• Hospitals and facilities requiring reliable secondary supply

Who is this for: This automatic transfer switch is intended for electricians, facility managers, and homeowners specifying a reliable, dual-source transfer device for 110V circuits up to 63A. Choose the Sejaede 2P switch when you need quick automatic switching with essential protective features and the option for manual control, especially where safety and uninterrupted power to select loads are priorities.
