Description
2-Pole 63A Manual Transfer Interlock Switch for Grid, Generator, IPS, Inverter & Backup Power Changeover
The FANHEY 2P 63A MTS Dual Power Manual Transfer Switch is a compact rail-mounted changeover device designed for manually switching an electrical load between two independent AC power sources.
It can be used to select between main grid electricity and generator, grid and inverter, grid and IPS, or other primary and backup power sources while mechanically preventing both sources from being connected to the load at the same time.
এই FANHEY 2P 63A Manual Transfer Switch (MTS) main electricity এবং backup power source-এর মধ্যে manually changeover করার জন্য ব্যবহার করা হয়। Grid power বন্ধ হলে user manually switch করে generator, inverter বা IPS supply select করতে পারে।
The 2-pole design is suitable for switching both Line and Neutral in compatible single-phase electrical systems.

How It Works / কীভাবে কাজ করে
The switch connects one of two power sources to a common load.
For example:
Source 1 → Grid / Main Electricity
Source 2 → Generator / Inverter / IPS
Output → Home / Office Load
When grid power is available, the user can select the grid source.
During a power failure, the user manually changes the switch position to select the backup source.
The mechanical interlock helps prevent both incoming sources from being ON together.
MTS vs ATS – Important Difference
This product is an MTS – Manual Transfer Switch.
MTS
MTS = Manual Transfer Switch
• User manually changes the power source
• Simple mechanical operation
• No automatic source detection
• Suitable where automatic transfer is not necessary
ATS
ATS = Automatic Transfer Switch
• Detects source failure automatically
• Transfers power automatically
• Usually includes control electronics
⚠️ This FANHEY product is manual, not an automatic ATS.
Why Use a Dual Power Interlock?
When two different power sources are available, they should not normally be connected together accidentally.
For example:
Grid + Generator
or
Grid + Inverter
The mechanical interlock ensures that selecting one source prevents the other source from being simultaneously connected through the transfer mechanism.
This makes manual power-source selection easier and safer when correctly installed.
2-Pole Switching Advantage
A 2P transfer switch can switch two conductors together.
In a compatible single-phase system, these may commonly be:
• Line / Phase
• Neutral
This can provide complete source isolation between two supplies when the installation design requires switched neutral.
⚠️ Neutral switching and earthing arrangements must follow the actual electrical system design and applicable installation requirements.
Suitable for Generator Backup
A common application is:
Utility Grid → MTS Source 1
Generator → MTS Source 2
MTS Output → Load Distribution
During grid failure:
- Turn off / isolate the normal source as required.
- Start the generator.
- Confirm generator output is stable.
- Manually select the backup source on the transfer switch.
When grid power returns, transfer can be manually returned to the normal source.
Suitable for Inverter / IPS System
The switch can also be used for manual selection between:
Grid ↔ Inverter
or
Grid ↔ IPS
This is useful where an inverter or IPS provides backup electricity but automatic source transfer is not required.
⚠️ Inverter output voltage, neutral arrangement and system topology must be compatible with the installation.
Installation Recommendation
A typical system may include:
Grid Supply
↓
Protection Breaker
↓
FANHEY MTS – Source 1
and
Generator / Inverter
↓
Protection Breaker
↓
FANHEY MTS – Source 2
then:
MTS Output → Distribution Board / Load
Each source should have appropriate protection according to the electrical design.
Important Installation Notes / গুরুত্বপূর্ণ নোট
⚠️ Installation should be performed by a qualified electrician.
⚠️ Disconnect all sources before installation or maintenance.
⚠️ Do not exceed the 63A rated current.
⚠️ Select cable size according to load current, cable length and installation conditions.
⚠️ Use appropriately rated upstream MCB/MCCB protection.
⚠️ Proper earthing and surge protection should be provided.
⚠️ Verify Line and Neutral connections carefully.
⚠️ Never intentionally bypass the mechanical interlock.
⚠️ Confirm generator/inverter neutral and earthing arrangement before installation.
⚠️ Do not assume the transfer switch itself replaces all required over-current protection.
⚠️ Product label, terminal arrangement and markings may vary slightly depending on stock batch.
Frequently Asked Questions / FAQ
What is the rated current?
The switch is rated at 63A.
How many poles does it have?
It is a 2-pole (2P) transfer switch.
Is this an ATS?
No. This is an MTS – Manual Transfer Switch.
Does it switch automatically during a power failure?
No. The user must manually select the required power source.
Can I use it between grid and generator?
Yes. Grid-generator manual changeover is one of its common applications.
Can I use it with an inverter or IPS?
Yes, provided the inverter/IPS and electrical system are properly designed and compatible.
Does it have an interlock?
Yes. The transfer mechanism provides mechanical interlocking between the two source positions.
Can it switch Line and Neutral?
A 2-pole unit can switch two conductors together, commonly Line and Neutral in an appropriately designed single-phase installation.
Can I install it on DIN rail?
Yes. It is designed for rail-mounted electrical panel installation.
Does it provide overload protection?
Do not rely on the transfer function as the only system protection. Appropriate MCB/MCCB and other protective devices should be selected according to the installation.
