RCBO 1P+N is the smart choice for single-phase circuits in Pakistan when you need earth leakage breaker protection and overload protection in one device. This CNC Electric Pakistan RCBO is available from 16A to 63A with 30mA sensitivity, giving both shock protection and circuit protection on one DIN rail module solution. Starting from Rs.1,700, it is ideal for home circuits feeding ACs, geysers, washing machines, water pumps, kitchen sockets, UPS lines, and other loads in Lahore, Karachi, Islamabad, Rawalpindi, Faisalabad, and Peshawar.

Quick Specs

What This Product Does

An RCBO combines the job of an MCB and an RCCB into one unit. That means it trips if there is overload or short circuit, and it also trips if electricity starts leaking to earth, which can happen because of damaged wiring, wet environments, or faulty appliances. People searching for rcbo, rcbo breaker, earth leakage breaker, or earth leakage circuit breaker usually want exactly this combined protection.

On a Pakistani home distribution board, an RCBO is especially useful for circuits that feed washing machines, kitchen sockets, water dispenser outlets, bathroom geyser lines, outdoor plugs, water pumps, inverter input circuits, and room ACs. If a person touches a faulty appliance body or if moisture causes leakage current, the 30mA sensitivity can disconnect the circuit quickly. At the same time, the RCBO still behaves like a circuit breaker for overload and short-circuit events.

Compared with using a separate RCCB plus a separate MCB, the RCBO saves space and makes one-circuit protection simpler. If you only need overcurrent protection, a regular 2P MCB may be enough. If you need both shock protection and overload protection on one single-phase circuit, the RCBO is usually the better answer.

Where an RCBO Makes the Biggest Difference

In Pakistan, voltage fluctuation gets a lot of attention, but leakage faults are just as serious because they can injure people. A damaged water pump cable, a metal-body washing machine with internal leakage, a damp outdoor socket, or a poorly insulated geyser line can all create dangerous conditions. The RCBO helps reduce that risk on one circuit without forcing you to redesign the entire board.

For example, a 1 ton AC or 1.5 ton AC circuit may only need an MCB for overload, but if the installation location is exposed to moisture or there is user contact risk, RCBO protection becomes much more attractive. The same applies to laundry areas, outdoor kitchens, roof-top socket lines, and any place where human contact and leakage risk are higher.

Selection Guide

How to Install

An RCBO should be installed by a licensed electrician because both the phase and neutral path must be handled correctly and test functionality should be checked after wiring.

• Turn off the main supply and confirm zero voltage before starting work.
• Mount the RCBO on the DIN rail inside the DB board.
• Connect incoming and outgoing phase and neutral exactly according to the product markings.
• After energizing, use the test button to confirm the RCBO trips correctly.
• Label the protected circuit clearly so future maintenance is easy.

What This Product Does NOT Protect Against

This RCBO does not protect against voltage spikes or lightning surges, so add an AC SPD if surge risk exists. It does not manage sustained overvoltage or undervoltage caused by weak utility supply, so use a VA protector if you need that function. It is also for single-phase circuits, not for three-phase systems where a 4P RCCB or a three-phase protection design is needed.

Put simply, RCBO covers one important package: earth leakage plus overcurrent on a single-phase line. For complete board protection, combine it with SPDs, voltage protectors, appropriate MCBs, and the right DB box layout.

Cross-Category Recommendations

If you are buying this RCBO, also consider the parts that complete a safe single-phase board. For incoming voltage control, add a VA protector. For lightning and transient surge protection, add an AC SPD. If your project is three-phase, compare the 4P RCCB. Read the RCBO vs ELCB guide and types of circuit breakers to help sales staff and electricians explain the difference to customers.

Browse MC4 connectors, DC cables, DC circuit breakers, DC SPD collection, solar bundles, AC circuit breakers, AC SPDs, voltage protectors, RCCB and RCBO, manual changeover switches, automatic transfer switches, DB boxes, and MCCBs for complete protection planning.

FAQs

What is RCBO full form?

RCBO stands for Residual Current Breaker with Overcurrent protection. It combines earth leakage protection and circuit breaker protection in one unit.

What is rcbo price in pakistan for this model?

This CNC Electric Pakistan RCBO starts from Rs.1,700, depending on the amp rating selected.

What is the difference between RCCB and RCBO?

An RCCB mainly covers leakage protection and usually needs an MCB for overload. An RCBO combines both functions in one device.

Can I use this RCBO for an AC?

Yes, if the selected amp rating matches the load and cable size. Many buyers use RCBOs on dedicated AC circuits where additional shock protection is desired.

Does this protect from electric shock?

It helps protect against dangerous leakage current by tripping at 30mA sensitivity, but proper earthing, wiring quality, and correct installation still matter.

Does RCBO replace a voltage protector?

No. It does not manage sustained overvoltage or undervoltage. Add a VA protector if you need voltage protection.

Do I still need an SPD with an RCBO?

Yes, if the site has surge risk. The RCBO does not replace an SPD for lightning-related transient protection.

Is this single phase or three phase?

This is 1P+N single phase. For three-phase installations, use the correct three-phase protective device such as a 4P RCCB or a suitable multi-pole arrangement.
