RCBO 4P Residual Current Circuit Breakers 32A, 63A YCB6HLN

4 pole RCBO buyers in Pakistan choose the RCBO 4P 32A-63A YCB6HLN when they need one device that combines earth leakage protection, overload protection, and short-circuit protection on a three-phase circuit. Starting from Rs.3,000, this three phase RCBO suits workshops, offices, lifts, small machinery feeders, commercial panels, and other 400V AC applications where panel space, simplicity, and safety all matter. For many sites in Pakistan, a 4P RCBO is the cleaner alternative to fitting a separate 4P RCCB plus a separate 4P MCB.

Quick Specs

What This Product Does

RCBO stands for Residual Current Circuit Breaker with Overcurrent protection. In plain words, it combines two jobs in one device. First, it trips on dangerous earth leakage. Second, it trips on overload and short circuit. For three-phase panels, that is a big advantage because it reduces device count and simplifies the wiring layout inside the board.

Many Pakistani buyers understand the difference only after panel space becomes a problem. A 4P RCCB only handles leakage protection; it still needs a separate 4P MCB for overload and short circuit. A 4P RCBO combines both roles. That is why it is attractive for smaller commercial panels, pumps, workshop feeders, and three-phase loads where compactness matters.

This product is especially useful where one three-phase outgoing circuit must be protected neatly in one modular device. It is not a substitute for surge protection or voltage quality protection, but it is the correct answer when the question is leakage plus overcurrent on a 3-phase line.

When a 4P RCBO Makes More Sense Than RCCB + MCB

Choose a 4P RCBO when you want one protective device for a three-phase feeder and you want to save space in the panel. It is practical in DB boards where multiple feeders already consume DIN rail space. It is also easier to explain to non-technical buyers because one product protects against two major categories of fault.

Choose separate devices when the design requires independent selection, coordination, or replacement of the RCCB and MCB functions. In bigger engineered panels, separate devices can still make sense. But for many real-world Pakistan jobs, especially compact panels, the all-in-one format is easier and cleaner.

Selection Guide

How to Install

This product should be installed by a licensed electrician or panel builder because three-phase wiring errors are costly and can be dangerous.

• Isolate the three-phase incoming supply and confirm zero voltage before touching the panel.
• Mount the RCBO on DIN rail and verify the correct incoming and outgoing terminal arrangement.
• Connect all poles correctly so phase sequence and neutral routing remain consistent with the design.
• Torque terminals properly and test the RCBO trip function before energizing the feeder.
• After commissioning, test leakage trip behavior and confirm load current is within the selected rating.

What This Product Does NOT Protect Against

This 4 pole RCBO does not protect against lightning and switching surges, so add a 4P AC SPD where surge risk exists. It does not protect against sustained overvoltage and undervoltage, so use a 3-phase VA protector if line conditions are poor. It is also not a substitute for good panel design, cable sizing, and coordination. The RCBO only covers earth leakage, overload, and short circuit on the protected circuit.

Cross-Category Recommendations

If you are buying a 4P RCBO, also look at the 1P+N RCBO for single-phase lines, the 4P RCCB if you need separate leakage protection, the 4P MCB for separate overcurrent control, the 4P 3-phase VA protector for voltage problems, and the 4P AC SPD for surge protection.

Browse AC circuit breakers, DC circuit breakers, AC breaker collection, DC breaker collection, MCCBs, AC SPDs, DC SPDs, voltage protectors, voltage regulators / stabilizers, RCCB / RCBO, types of circuit breakers, solar DB guide, RCBO vs ELCB guide, types of circuit breakers guide, voltage protector vs stabilizer. This helps buyers understand where RCBO protection stops and where SPD or voltage protection begins.

FAQs

What is a 4 pole RCBO used for?

A 4 pole RCBO is used on three-phase circuits where you want both earth leakage protection and overcurrent protection in one device.

What is the RCBO price in Pakistan for this model?

This product starts from Rs.3,000. It is a practical three-phase protection option for buyers who want one compact device.

Is a 4P RCBO better than a 4P RCCB?

They do different jobs. A 4P RCBO includes overload and short-circuit protection as well, while a 4P RCCB needs a separate MCB.

Can I use this for a three-phase office or shop?

Yes, that is one of the most common use cases, provided a licensed electrician confirms the correct rating and panel design.

Does it protect against surges?

No. Add a 4P AC SPD for lightning and switching surges because an RCBO is not a surge protector.

Does it protect against low voltage and high voltage?

No. For sustained overvoltage and undervoltage, add a 3-phase VA protector on the incoming line where needed.

What is 30mA sensitivity for?

30mA is commonly used for personal-protection-level earth leakage tripping, helping disconnect a circuit when leakage becomes dangerous.

Is this available across Pakistan?

Yes, CNC Electric Pakistan supplies across Lahore, Karachi, Islamabad, Rawalpindi, Faisalabad, Peshawar, and other cities with free delivery positioning in these product pages.

For three-phase safety, the right protective chain is usually RCBO or RCCB, plus MCB coordination, plus SPD and voltage protection where needed.
