Product Description

The Eaton NHG3B breaker, specifically the 630NHG3B 630A 690VAC circuit breaker, is designed for high-performance power distribution in demanding industrial environments. This 3-pole breaker supports a rated current of 630A and operates at 690VAC, with a wide voltage tolerance of 550–690VAC. It integrates directly with modular accessories like shunt trips, under-voltage releases, and auxiliary contacts for flexible configuration. The Eaton 630NHG3B 690VAC model features a compact design, reducing panel space, and offers robust protection against overloads, short circuits, and electrical faults. Suitable for manufacturing, energy, and heavy industries, it operates reliably within -25°C to +70°C. Key advantages include high breaking capacity (up to 70kA) and compatibility with communication protocols like Modbus via optional modules. While lacking a display or battery, its mechanical indicators ensure clear status monitoring. Installation requires adherence to Eaton’s guidelines for optimal safety and performance.
