RNM DZ47LE-63 C63 2P RCBO Circuit Breaker Price in Bangladesh

The RNM DZ47LE-63 C63 2P RCBO Circuit Breaker is a high-performance electrical protection device that combines the functions of both a Miniature Circuit Breaker (MCB) and a Residual Current Circuit Breaker with Overcurrent Protection (RCBO) into a single compact unit. Designed to provide comprehensive protection against overload, short circuits, and earth leakage faults, this RCBO is an essential safety component for modern residential, commercial, and industrial electrical distribution systems.

Unlike a standard MCB that only protects against overloads and short circuits, an RCBO continuously monitors the current flowing through both the live and neutral conductors. If it detects an imbalance caused by current leaking to earth—such as through faulty insulation, damaged equipment, or accidental human contact—it disconnects the circuit almost instantly, helping to reduce the risk of electric shock and electrical fires. Typical residual current trip times are within 0.1 seconds, providing fast and reliable protection.

The C63 rating indicates a 63A current capacity with a Type C tripping characteristic, making it suitable for circuits supplying moderate inductive loads such as air conditioners, pumps, motors, compressors, and lighting systems where temporary inrush current occurs during startup. The 2-pole (2P) design disconnects both the live and neutral conductors simultaneously, offering enhanced electrical safety during fault conditions.

Built according to IEC 61009 standards, the DZ47LE-63 series is designed for dependable long-term operation in distribution boards and electrical control panels. It supports installation on standard 35mm DIN rails, allowing quick integration into new or existing electrical systems. The compact design helps save valuable space inside electrical panels while simplifying wiring and maintenance.

The breaker incorporates thermal and magnetic trip mechanisms to detect overloads and short circuits, while the integrated residual current detection circuit monitors earth leakage. Many versions also include a convenient TEST button that allows users to verify proper operation of the leakage protection mechanism periodically, ensuring continued safety throughout the life of the installation.

The RNM DZ47LE-63 RCBO is widely used in household distribution boards, office buildings, factories, commercial complexes, workshops, schools, hospitals, solar power systems, and industrial control panels. Its ability to provide multiple layers of protection in a single device makes it an economical and highly reliable solution for modern electrical installations.

Whether protecting household appliances, industrial machinery, lighting circuits, or power outlets, the RNM DZ47LE-63 C63 2P RCBO helps improve electrical safety, minimize equipment damage, and ensure compliance with modern electrical protection standards.

🔍 What is an RCBO Circuit Breaker?

An RCBO (Residual Current Circuit Breaker with Overcurrent Protection) combines the functions of an MCB and an RCD/RCCB into one device.

It protects electrical circuits from:

• Overload current
• Short circuit faults
• Earth leakage current
• Electric shock hazards
• Electrical fire risks

This combination makes RCBOs one of the safest protection devices for modern electrical installations.

⚡ Working Principle of RNM DZ47LE-63 C63 2P RCBO Circuit Breaker

The RCBO continuously monitors both the live and neutral currents passing through the device.

Under normal conditions, the incoming and outgoing currents remain equal. If a leakage current occurs due to insulation failure or accidental contact with a live conductor, the current becomes unbalanced. The internal residual current detection circuit immediately senses this imbalance and trips the breaker.

Additionally, the thermal element protects against prolonged overloads, while the magnetic mechanism responds instantly to short circuits. This combination provides complete protection against the most common electrical faults.
