GDC2-63 AC MCB Overview

Le GDC2-63 AC MCB is a compact miniature circuit breaker designed for overload and short-circuit protection in low-voltage AC electrical systems. With rated currents from 1 A à 63 A, a rated breaking capacity of 6 kA, and multiple pole configurations, the series can be used in residential distribution boards, commercial electrical panels, industrial control cabinets and OEM equipment.

Le GDC2-63 AC MCB est disponible en 1P, 2P, 3P et 4P versions, allowing the same product family to cover both single-phase and three-phase protection requirements. Rated voltage reaches 240/415V AC, with a frequency of 50/60 Hz.

Three thermo-magnetic trip characteristics are available:

• B Curve
• C Curve
• D Curve

These trip curves allow the GDC2-63 series to be matched to different load conditions. B curve models are suitable for circuits with lower inrush current, C curve models are commonly used for general distribution and equipment circuits, while D curve versions can be selected for loads with higher starting currents.

Compared with the GDC1-63 series, the GDC2-63 AC MCB provides a higher Capacité de coupure de 6 kA, making it suitable for installations where a greater short-circuit interruption capability is required.

The breaker is designed for standard Montage sur rail DIN de 35 mm, making installation and replacement straightforward inside modular electrical panels.

Caractéristiques du produit

Le GDC2-63 AC MCB provides a rated short-circuit breaking capacity of 6 000 A.

This higher breaking capability makes the series suitable for residential, commercial and industrial distribution systems where prospective fault current may exceed the capability of a standard 4.5kA MCB.

Available current ratings include:

1A, 2A, 3A, 4A, 5A, 6A, 8A, 10A, 16A, 20A, 25A, 32A, 40A, 50A and 63A.

This wide selection allows the GDC2-63 AC MCB to protect different branch circuits, loads and electrical equipment.

The GDC2-63 series is available in:

• 1P
• 2P
• 3P
• 4P

Multiple pole options simplify product selection for different single-phase and three-phase installations.The GDC2-63 AC MCB supports B, C and D thermo-magnetic characteristics, making the series adaptable to different load profiles and inrush-current requirements.A built-in contact position indicator provides a clear visual reference of breaker status, helping technicians during inspection and maintenance.The breaker is designed for mounting on a standard 35mm DIN rail, supporting compact installation in modular distribution and control equipment.

Applications of GDC2-63 AC MCB

Le GDC2-63 AC MCB is suitable for a wide range of low-voltage electrical protection applications, including:

• Tableaux de distribution résidentiels
• Tableaux électriques commerciaux
• Armoires de commande industrielles
• Circuits d'éclairage
• Power distribution systems
• Machinery control circuits
• HVAC electrical equipment
• Building electrical installations
• Ensembles électriques OEM
• Small motor and equipment circuits

The combination of a Capacité de coupure de 6 kA, multiple pole options and B/C/D trip characteristics makes the GDC2-63 suitable for both general-purpose and more demanding AC protection applications.

Selecting a GDC2-63 AC MCB

When selecting a GDC2-63 AC MCB, engineers should consider more than the rated current.

Important selection factors include:

• Load current
• Cable capacity
• System voltage
• Number of poles
• Prospective short-circuit current
• Required trip curve
• Upstream and downstream protection coordination

For standard distribution circuits, Courbe en C is commonly used. B curve may be preferred for lower-inrush loads, while D curve can be selected where equipment produces higher starting currents.

The selected GDC2-63 breaker should always match the conductor capacity and electrical characteristics of the protected circuit.
