Descrição
GDC1-63 AC MCB Overview
O 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 1 A a 63 A, the series provides flexible protection options for lighting circuits, power distribution, control panels and general electrical equipment.
O GDC1-63 AC MCB está disponível em 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 4,5 kA.
Three thermo-magnetic tripping characteristics are available:
- Curva B
- Curva C
- Curva D
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.
O GDC1-63 AC MCB is designed for standard Montagem em calha DIN de 35 mm, making it easy to integrate into distribution boards, control cabinets and modular electrical assemblies.
