GDC1-63 AC MCB Overview

Şu GDC1-63 AC MCB is a compact miniature circuit breaker designed to provide overload and short-circuit protection in residential, commercial and industrial low-voltage electrical systems. With rated currents from 1A to 63A, the series provides flexible protection options for lighting circuits, power distribution, control panels and general electrical equipment.

Şu GDC1-63 AC MCB is available in 1P, 2P, 3P and 4P configurations, allowing the same product family to be used in single-phase and three-phase electrical installations. Rated voltage options include 240V / 415V AC, while the rated breaking capacity reaches 4.5kA.

Three thermo-magnetic tripping characteristics are available:

• B Curve
• C Curve
• D Curve

These curve options help engineers match the breaker to different load characteristics. B curve models are commonly used for circuits with lower inrush current, C curve versions are widely applied to general distribution and motor-related loads, while D curve models are suited to circuits with higher starting or inrush currents.

Şu GDC1-63 AC MCB is designed for standard 35mm DIN rail mounting, making it easy to integrate into distribution boards, control cabinets and modular electrical assemblies.

Selecting a GDC1-63 AC MCB

When selecting a GDC1-63 AC MCB, the rated current should be matched to the cable capacity and connected load. Engineers should also consider pole configuration, system voltage, expected short-circuit current and trip curve.

For general-purpose electrical circuits, C curve is commonly selected. B curve may be preferred for circuits with lower inrush current, while D curve can be considered for equipment with higher startup current.

The breaker should always be coordinated with upstream and downstream protective devices to ensure reliable circuit protection.
