Introduction

A miniature circuit breaker (MCB) is an electrical protection device that automatically switches off an electrical circuit in case of an over-current, over-voltage, or short circuit. MCBs are used in residential and commercial applications where only one phase of power is delivered (single-phase) to protect the wiring and equipment from damage caused by overcurrents. MCBs are equipped with two tripping mechanisms: the delayed thermal tripping mechanism for overload protection and the magnetic tripping mechanism for short circuit protection.

Miniature Circuit Breakers (MCBs) ensure electrical safety in homes, offices and other buildings as well as for industrial applications by protecting electrical installations against overloads and short-circuits. Once a fault is detected, the MCB automatically switches off the electrical circuit to prevent damage to wires and to avoid the risk of fire. MCBs are equipped with two tripping mechanisms: the delayed thermal tripping mechanism for overload protection and the magnetic tripping mechanism for short circuit protection.

For 100 years, we have continued to innovate MCBs and expand our product line to meet the demands of various applications and markets. Our products are compliant with global product standards such as IEC, UL and CSA. This established and certified portfolio is designed to provide maximum safety for buildings, assets and infrastructure.

• Compliant to worldwide product standards (IEC, UL, CSA)
• Characteristics: B, C, D, K, ZConfigurations: 1P, 1P+N, 2P, 3P, 3P+N, 4P
• Breaking capacities up to 25 kARated currents up to 100 A

DZ49-63 are intended for protecting distribution and group systems having different loads:

- electric appliances, lighting – V characteristic switches;

- drives with moderate starting currents (compressor, fan group) - C characteristic switches;

- drives with high starting currents (hoisting mechanisms, pumps) - D characteristic switches;

Miniature circuit breaker DA47N-63 are recommended for use in electrical distribution panels of residential and public buildings.
