Quick Selection Tips
Use the filters above (Postes y Actual) to narrow down models. Then check each product’s Especificaciones y cableado for diagrams and terminal details. Here are some quick guidelines to help you choose correctly:
Choose by Poles
- 1P: Single-phase line switching only (neutral fixed).
- 2P: Single-phase line + neutral switching (common for residential backup).
- 3P: Three-phase systems without neutral switching.
- 4P: Three-phase + neutral switching for full isolation and safer maintenance.
Choose by Current
- 63A: Suitable for small homes, offices, telecom cabinets, and light loads.
- 125A: Suitable for larger houses, workshops, and small industrial facilities.
- Always size the switch ≥ your main breaker o generator output (whichever is higher).
- For long cable runs or planned expansion, select the next higher rating.
What is a Manual Transfer Switch?
A Manual Transfer Switch (MTS) is a device that safely connects a building’s electrical system to a backup power source, such as a generator. During an outage, the MTS allows the user to manually switch from the utility line to the generator, ensuring that critical loads remain powered. Unlike improvised methods, a certified MTS provides clear ON/OFF/I-0-II positions, mechanical interlocking, and compliance with safety standards such as IEC 60947-6-1 y UL 1008.

- Lower cost, compact design.
- Ideal for homes, workshops, and backup systems with occasional outages.
Interruptor de transferencia automática (ATS)
- Switches automatically when power fails.
- Higher cost, requires control circuits.
- Preferido para sistemas de misión crítica (centros de datos, hospitales).
Aplicaciones y casos prácticos
Residential Backup
Keep essential home loads powered during outages by safely switching between utility and a portable generator. Recommended 2P models for neutral isolation.
Small Businesses
Shops, clinics, and restaurants can ensure lights and refrigeration keep running with an MTS. Cost-effective backup without full ATS investment.
Workshops & Light Industry
Manual Transfer Switches provide reliable power continuity for tools, machinery, and small industrial sites, ensuring safe manual control of generator changeover.
Telecom & Remote Cabinets
Critical telecom and IT enclosures require quick backup. MTS units allow fast, safe generator hook-up without risking live line backfeed.
Solar & ESS Integration
When paired with solar or storage systems, manual transfer switches provide a manual fallback option, meeting safety codes and ensuring clear isolation.
Emergency Shelters
Community shelters and off-grid bases rely on simple, durable changeover switches for secure backup. Contact us to configure the right rating.

Technical Parameters & Selection Guide
The Kuangya Manual Transfer Switch (MTS) series is designed to meet IEC 60947-6-1 y UL 1008 standards. Available in 63A and 125A, with 1P/2P/3P/4P options, our MTS units provide safe and reliable changeover for residential, commercial, and light industrial use. Use the table below to compare ratings and ensure proper sizing.
| Modelo | Postes | Corriente nominal (In) | Tensión nominal (Ue) | Tensión de aislamiento (Ui) | Utilization Category | Capacidad de la terminal | Montaje |
|---|---|---|---|---|---|---|---|
| KYMTS-63A | 1P / 2P / 3P / 4P | 63A | AC 250V (1P) / AC 500V (2P) / AC 750V (3P) / AC 1000V (4P) | AC 1000V | AC-22A | 16–35 mm² Cu | DIN rail / panel |
| KYMTS-125A | 1P / 2P / 3P / 4P | 125A | AC 250V (1P) / AC 500V (2P) / AC 750V (3P) / AC 1000V (4P) | AC 1000V | AC-22A | 25–50 mm² Cu | DIN rail / panel |
Selection tips: Choose current rating equal to or greater than the main breaker or generator output. For single-phase loads requiring full isolation, select a 2P unit. For three-phase systems, choose 3P o 4P depending on whether neutral switching is required.
For wiring diagrams and installation details, please check the individual model pages or contact our technical support.
Note on Utilization Category: All Kuangya Manual Transfer Switches are classified under AC-22A according to IEC 60947-6-1. This category covers the switching of mixed resistive and inductive loads, including moderate overloads, making it suitable for interruptores de transferencia manual used in residential, commercial, and light industrial applications. By contrast, AC-20A is for isolators only, while AC-23A applies to motor load switching.
