Multifunction Combined Residual Current Circuit Breaker (RCBO)

Description

The Dena Multifunction Combined Residual Current Circuit Breaker (RCBO), with its unique design, combines a Miniature Circuit Breaker (MCB) and a Residual Current Device (RCD) in a single unit. One section provides protection against overload and short circuits, while the other provides protection against current leakage and electric shock. This product features two separate handles (Dual Handle), allowing the type of fault to be distinguished. As a result, the user can easily determine whether the circuit has tripped due to current leakage or as a result of overload or a short circuit. In addition to enhancing safety, this feature makes troubleshooting and resolving electrical system faults faster and easier.

The Dena Multifunction RCBO is designed and manufactured in accordance with EN/IEC 61008-2-2 and is available in rated currents of 16, 20, 25, 32, 40, 50, and 63A, with a breaking capacity of 6kA. This product is suitable for 230V single-phase networks and is available with a C tripping curve, making it suitable for a wide range of residential, commercial, and industrial applications.

The Multifunction Combined Residual Current Circuit Breaker (RCBO) is generally available in two models:

**MR Model (Magnetic):** The tripping mechanism operates based on a magnetic circuit breaker, while leakage current is detected by a coil (differential current transformer).

**ER Model (Electronic):** Leakage current is detected by an electronic circuit or board. Once leakage is detected, a trip command is sent to the circuit breaker’s tripping mechanism.

Using the Dena Combined RCBO not only improves personal safety against electric shock but also protects electrical equipment against damage caused by short circuits and overloads. In addition, by integrating two protective devices into a single product, it occupies less space inside the electrical panel, reduces installation costs, and simplifies panel wiring.

If you are looking for a high-quality Dena RCBO with international standards, precise performance, and a long service life, the Dena Multifunction models are a reliable choice for building and industrial projects, electrical distribution panels, and electrical installations. With its fault-type identification capability, easy installation, and comprehensive circuit protection, this product is one of the suitable options for improving the safety of electrical networks.
