GDC2-63 AC MCB Overview

O 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 a 63 A, a rated breaking capacity of 6kA, and multiple pole configurations, the series can be used in residential distribution boards, commercial electrical panels, industrial control cabinets and OEM equipment.

O GDC2-63 AC MCB está disponível em 1P, 2P, 3P e 4P versions, allowing the same product family to cover both single-phase and three-phase protection requirements. Rated voltage reaches 240/415 V CA, with a frequency of 50/60 Hz.

Three thermo-magnetic trip characteristics are available:

• Curva B
• Curva C
• Curva D

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 Capacidade de corte de 6 kA, making it suitable for installations where a greater short-circuit interruption capability is required.

The breaker is designed for standard Montagem em calha DIN de 35 mm, making installation and replacement straightforward inside modular electrical panels.

Características do produto

O GDC2-63 AC MCB provides a rated short-circuit breaking capacity of 6000 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.

As intensidades de corrente disponíveis incluem:

1A, 2A, 3A, 4A, 5A, 6A, 8A, 10A, 16A, 20A, 25A, 32A, 40A, 50A e 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 Trilho DIN de 35 mm, supporting compact installation in modular distribution and control equipment.

Selecting a GDC2-63 AC MCB

Ao escolher um GDC2-63 AC MCB, engineers should consider more than the rated current.

Important selection factors include:

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

For standard distribution circuits, C curve 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.
