Product Description

The Eaton 630NHG4B-690 breaker is a high-performance NHG4B-690 circuit breaker designed for industrial power distribution systems. Rated at 630A and 690VAC, it features a fixed three-pole design with integrated thermal-magnetic protection. This Eaton 630A 690VAC breaker supports direct connection to standard power modules and includes optional communication interfaces like Modbus for real-time monitoring. Its operational voltage range spans 400-690VAC, with an operating temperature range of -25°C to +70°C. Ideal for heavy industries, energy infrastructure, and manufacturing, it offers high interrupting capacity (up to 50kA) and robust construction for harsh environments. The breaker lacks onboard battery or display but ensures reliable tripping accuracy. Compact dimensions (typical width 180mm) and tool-free adjustments simplify installation. Key advantages include durability and compliance with IEC standards, though it requires external metering for advanced diagnostics.
