Legrand 4P RCCB Earth Leakage Circuit Breakers

Legrand Earth Leakage Circuit Breakers are designed to provide residual-current protection in electrical installations by detecting leakage current and disconnecting the circuit when the specified residual-current threshold is reached. Legrand’s RCCB range includes different configurations for residential, commercial and other low-voltage applications, with options varying by rated current, number of poles, sensitivity and leakage-current type.

At HN Electric, you can select the Legrand RCCB specification according to your electrical installation rather than choosing a breaker based only on ampere rating. Depending on the model, Legrand offers 2-pole and 4-pole RCCBs, including products designed for 230V single-phase and 400V three-phase applications. Available sensitivities can include 30mA, 100mA and 300mA, while the product range includes AC and A-type devices.

For example, Legrand’s TX³ range includes a 2-pole, 230V, 40A, 30mA AC-type RCCB, while the DX³ range includes several 2-pole and 4-pole configurations. The official Legrand catalogue also lists 40A and 63A variants and different residual-current sensitivities. Always check the exact reference number and technical specification before ordering.

An RCCB is different from a conventional MCB. An RCCB is primarily intended to detect residual or earth-leakage current; it should not be described as a replacement for overcurrent protection unless the specific product is an RCBO that combines residual-current and overcurrent protection. HN Electric’s own electrical guidance similarly distinguishes RCCBs from MCBs and RCBOs.

When selecting a Legrand RCCB, check the number of poles, rated current, rated voltage, residual-current sensitivity, AC/A type, breaking/withstand characteristics and physical compatibility with the distribution board. Installation should be carried out by a qualified electrician using the manufacturer’s instructions.

If you are looking for the Legrand RCCB price in Pakistan, HN Electric can provide the applicable price according to the exact model and rating selected. For customers in Lahore and other cities across Pakistan, confirm stock, model/reference and delivery availability before placing a larger project order.

FAQs

1. What is a Legrand RCCB?

A Legrand RCCB is a residual-current circuit breaker designed to detect earth-leakage/residual current and disconnect the circuit when its specified threshold is reached. Legrand markets RCCBs under ranges including DX³ and TX³.

2. What is the difference between RCCB and ELCB?

RCCB means Residual Current Circuit Breaker. ELCB, or earth leakage circuit breaker, is a commonly used term for earth-leakage protection. Product terminology can vary by market, so buyers should verify the exact manufacturer’s product designation and specifications.

3. Which Legrand RCCB should I choose?

Selection depends on the installation: 2P or 4P, rated current, voltage, 30mA/100mA/300mA sensitivity and AC/A type should all be checked against the electrical design. A qualified electrician should make the final selection.

4. Does an RCCB replace an MCB?

Not normally. An RCCB provides residual-current protection, while an MCB provides overcurrent/short-circuit protection. An RCBO combines residual-current and overcurrent protection in one device.
