A 3 pole changeover breaker is the practical answer when you need manual source selection in a three-phase panel without moving to a larger plate-mounted switch or a costlier ATS. This CNC Electric listing is tracked in the project product data at Rs.1,500 for the 63A 3P DIN-rail version. It suits workshops, pump panels, generator boards, inverter bypass arrangements and compact utility DBs where the operator is expected to transfer source deliberately and safely.
The important point is this: this is a manual transfer device, not an automatic one. Its job is to let you choose one source, isolate at the center OFF position, and then move to the second source. In Pakistan, that matters in real settings where WAPDA supply, generator backup and inverter supply are all part of the same conversation. A neat DIN-rail form also helps when the panel builder wants the device inside the enclosure instead of sticking out like an external rotary plate switch.
Key Features
- 3 pole manual changeover breaker for three-phase source selection
- 63A local sale variant in the current project data
- DIN rail mounting for internal panel installation
- 1-0-2 transfer logic for source one, OFF, and source two
- IEC 60947-3 switch disconnector class in the official YCBZ family
- Better fit than EP type when the goal is compact internal mounting
- Useful for generator, inverter and utility source transfer in non-automatic setups

This description uses the local sale data currently available in the project files plus official YCBZ family technical references. The current live page for this exact 3 pole 63A listing was not surfaced cleanly during checking, so body dimensions beyond the published family drawing, terminal diagram specifics for the local sales page, and any local selector-specific accessory data have not been guessed.
Product Range and Models
| Model | Poles | Amp rating | Mounting | Price |
|---|---|---|---|---|
| YCBZ local sale variant | 3P | 63A | DIN rail | Rs.1,500 |
| Comparable family example | 4P | 63A / 100A / 125A | DIN rail | See live 4P page |
This is the cleaner option when you need three-phase manual transfer inside a cabinet and do not need a neutral-switched 4P device. If the project specifically requires neutral isolation along with the three phases, move up to a 4 pole changeover. If the site requires automatic transfer on outage, move to an automatic transfer switch instead of trying to force a manual unit into an automatic duty.
Applications in Pakistan
This type of 3 pole DIN rail changeover breaker makes sense in smaller three-phase boards where manual transfer is acceptable and the operator can physically move the switch between sources. In Lahore, that can mean workshop panels with grid and generator supply. In Karachi, it suits compact utility boards in commercial buildings where panel space is tight. In Faisalabad, smaller production lines and service boards often need a clean internal source selector rather than a larger external plate type. The main advantage is neat panel integration, not automation.
| Application | Recommended setup | Why this model fits |
|---|---|---|
| Three-phase workshop backup board | 63A 3P DIN rail changeover with upstream breakers | Compact internal mounting and manual source transfer |
| Generator and mains source selection | Manual 1-0-2 transfer inside a metal panel | Useful where a person is expected to change sources deliberately |
| UPS or inverter bypass board | Three-phase internal selector | Cleaner than a larger EP plate type when enclosure space is managed on rail |
| Small industrial utility panel | 3P manual source selector with voltage and surge protection around it | Practical when automatic transfer is not required |
| Compact distribution board build | DIN rail line-up with MCB/MCCB, SPD and voltage protector | The DIN format keeps the board tidy and serviceable |
How to Choose the Right 3 Pole Changeover Breaker
| Your situation | Choose this product? | Reason |
|---|---|---|
| Three-phase supply, manual transfer acceptable, no switched neutral required | Yes | This is the clean intended use case |
| Need neutral switching too | No | Choose a 4 pole changeover instead |
| Need automatic transfer on power failure | No | Use an ATS, not a manual switch |
| Want a visible external panel-door handle | Maybe not | An EP plate switch may suit that format better |
3 Pole DIN Changeover vs Alternatives
| Point | 3P DIN rail changeover | EP plate changeover | ATS |
|---|---|---|---|
| Main advantage | Neat internal DIN-rail mounting | Larger external manual operator | Automatic source transfer |
| Best use | Compact three-phase DB or utility board | External panel-door or plate-style manual operation | Critical loads that cannot wait for manual transfer |
| Selection logic | Pick when manual transfer is acceptable and space is tight | Pick when a more visible manual operator is preferred | Pick when no operator intervention can be tolerated |
What This Product Does NOT Protect Against
This product does not correct bad voltage, stop surge damage, replace upstream short-circuit protection, or behave like an automatic transfer switch. It is not a voltage protector, not an SPD, and not a substitute for MCB or MCCB coordination. It is a manual source selector for normal operating conditions.
If the board also needs protection, add the right circuit breakers, a suitable voltage protector, proper surge protection, and if the site must transfer automatically, the correct ATS.
Installation Guide
- Mount the unit on a 35mm DIN rail inside a rigid enclosure with clear source and load identification.
- Bring source I, source II and load conductors according to the intended 3P 1-0-2 panel layout.
- Keep conductor sizing appropriate for the current class and panel design. The official 63A family guide shows a 50mm² family terminal reference.
- Before energizing, verify that source I, OFF, and source II positions are physically correct and there is no backfeed confusion.
- Test manual operation several times without load first, then commission the full board only after confirming correct transfer logic.
