Changeover Breaker Complete Guide in Pakistan
A changeover breaker is an essential electrical device used to safely switch power supply between two different sources, such as WAPDA and generator, UPS, or solar inverter. In Pakistan, frequent load shedding has made electric changeover systems a necessity for homes, offices, factories, and commercial buildings.
Whether you are using a manual changeover switch or an automatic changeover switch, the main purpose is to ensure uninterrupted power while protecting electrical equipment from damage.
What is a Changeover Breaker?
A change over circuit breaker is a protective switching device that transfers electrical load from one power source to another. Unlike simple switches, it also provides overcurrent and short-circuit protection, making it safer than traditional changeover switches.
It is commonly used as:
- Breaker switch
- AC breaker switch
- Electric changer
- Current changer
Types of Changeover Devices
Manual Changeover Switch
A manual changeover switch requires human operation to shift power between sources. It is simple, cost-effective, and widely used in homes.
3 Phase / Three Phase Changeover Switch
three phase changeover switch is used in industrial and commercial setups where three-phase supply is required.
Ampere Ratings
- 1 to 4Pole: Available in 63 Amp
- 4 Pole: Available in
- 63A
- 100A
- 125A
These ratings make changeover breakers suitable for domestic, commercial, and industrial loads.

Changeover Connection Overview
A changeover connection ensures that:
- Two power sources never connect at the same time
- Load is safely transferred without back-feeding
- Electrical appliances remain protected
Why Choose a Changeover Breaker?
A changeover breaker offers both switching and protection, making it ideal for:
- Sensitive electronics
- Air conditioners (AC breaker switch)
- Industrial machines
- High current loads
It ensures safe power transfer without damaging appliances.
Conclusion
A changeover breaker is an essential electrical component in Pakistan’s power-challenged environment. Whether you need a 63A manual changeover, a 4 pole automatic changeover switch, or a three phase changeover switch, selecting the right model ensures safety, reliability, and uninterrupted power supply.
