Product Overview: ABB NAMC-11C / 64057642
Brand
Series
NAMC Series (Motor Protection Circuit Breaker)
Product Description
The ABB NAMC-11C (64057642) is a compact motor protection circuit breaker (MPCB) designed for low-voltage applications to protect motors against overload, short circuits, and phase failure. This breaker integrates thermal-magnetic protection and is specifically engineered for small to medium motors.
Its precise tripping curve ensures optimal motor protection, preventing damage due to mechanical stress while minimizing nuisance tripping. The NAMC-11C features high reliability, long operational lifetime, and easy integration into modular control panels. The device also allows quick manual disconnection of motors during maintenance.
Applications
-
Protection of industrial motors in factories and production lines.
-
Electrical panels for HVAC systems in commercial and residential buildings.
-
Pumps, compressors, and conveyor systems in industrial automation.
-
Small to medium-sized machinery in workshops and assembly lines.
-
Motor-driven equipment in renewable energy plants (e.g., small wind turbines or solar trackers).
Product Advantages
-
Reliable Motor Protection – Provides thermal-magnetic protection against overloads and short circuits.
-
Compact Size – Saves space in control panels.
-
Long Operational Life – Designed for repeated tripping cycles and long-term reliability.
-
Manual Control Functionality – Allows safe motor disconnection for maintenance.
-
