25A Automatic Transfer Switch (ATS), CSQ HYCQ5-125G – Best 125A ATS Price in Bangladesh | STCMart

Looking for a reliable 2P 125A Automatic Transfer Switch (ATS) in Bangladesh at a competitive price? The CSQ HYCQ5-125G 2P 125A Dual Power Automatic Transfer Switch is an ideal solution for single-phase electrical systems requiring reliable and automatic transfer between two power sources. Available from STCMart, a trusted supplier of electrical and solar products in Bangladesh, this CSQ 125A ATS is suitable for residential, commercial, solar hybrid, generator backup, UPS, and other dual-power applications.

The CSQ HYCQ5-125G 2P 125A ATS is designed for single-phase power systems where both Live and Neutral need to be managed through a dual-power transfer arrangement. With a rated current capacity of up to 125A, it is suitable for higher-load residential and commercial installations where a smaller 40A, 63A, or 100A transfer switch may not be sufficient.

For customers searching for the best 125A ATS price in Bangladesh, STCMart offers the CSQ HYCQ5-125G as a practical combination of high current capacity, automatic transfer functionality, and reliable dual-power management.

125A ATS for Single-Phase Power Systems

The CSQ HYCQ5-125G 2P is specifically suited to single-phase AC power systems. Its 2-pole configuration allows the switching of both Live and Neutral conductors, making it suitable for many single-phase residential and commercial power distribution applications.

The ATS is designed to monitor the availability of two power sources. When the normal power source becomes unavailable or abnormal, the system can transfer the connected load to the alternative power source according to its control logic. When the normal source becomes available again, the ATS can return the load to the preferred source.

This automatic source management reduces the need for manual intervention and makes it particularly useful for backup power systems.

125A ATS for Solar Hybrid Systems

The CSQ HYCQ5-125G 2P 125A is an excellent option for appropriately designed Solar Hybrid Systems where reliable switching between grid power and an alternative AC source is required.

In a typical hybrid solar application, the two sources may consist of:

Grid Power → Solar Hybrid Inverter

or

Grid Power → Backup Generator

or

Grid Power → UPS/Backup Source

The exact configuration depends on the inverter architecture and electrical system design.

When the primary source is unavailable, the ATS can automatically transfer the load to the alternative source. This helps reduce downtime and provides a convenient way of managing multiple power sources.

ATS as a Bypass Switch for Solar Inverter

One of the most valuable applications of a 2P ATS in a solar hybrid system is its use as part of an inverter bypass arrangement.

Solar hybrid inverters may occasionally require maintenance, servicing, troubleshooting, or replacement. If the electrical system has no suitable bypass arrangement, servicing the inverter can result in power interruption to the connected loads.

A properly designed ATS arrangement allows the load to be transferred to the alternative source, such as the utility grid, while the inverter is isolated for maintenance.

This makes the CSQ 2P 125A ATS a useful component for solar installations where serviceability and power continuity are important.

Important: The ATS should be installed and configured according to the inverter manufacturer’s instructions, electrical protection requirements, and applicable installation standards. A qualified electrician should verify the system before commissioning.

High 125A Current Capacity

With a rated current of 125A, the CSQ HYCQ5-125G 2P can handle significantly higher loads than conventional 40A or 63A ATS units.

It is suitable for applications such as:

• Large residential houses
• Duplexes and apartments
• Offices
• Shops and commercial buildings
• Solar hybrid systems
• Generator backup systems
• UPS backup systems
• Agricultural applications
• Workshops
• Selected light industrial applications

The actual load capacity should always be determined based on the connected load, cable size, upstream protection, fault level, and overall electrical design.

Automatic Dual-Power Transfer

The primary function of the HYCQ5-125G is automatic transfer between two available power sources. When the normal source experiences an abnormal condition or power failure, the ATS detects the condition and transfers the load to the alternative source.

This is especially useful in Bangladesh, where power interruptions and voltage-related issues can affect residential and commercial operations.

Instead of manually operating a changeover switch every time the grid fails, an automatic transfer switch provides a more convenient solution for managing backup power.
