Product Description

The Eaton 400NHG03B breaker is a robust NHG03B circuit breaker designed for high-power industrial applications, offering a 400A continuous current rating and 690VAC voltage capacity. This Eaton 400A 690VAC breaker features a compact, fixed-mount design with a single input/output configuration, supporting direct integration into power distribution panels. It operates within a wide voltage range of 400-690VAC and withstands ambient temperatures from -25°C to +70°C, ensuring reliability in harsh environments like manufacturing plants or energy facilities. Key advantages include high interrupting capacity, thermal-magnetic trip protection, and tool-free installation, while its lack of integrated communication ports may require external modules for smart-grid compatibility. The breaker meets IEC 60947-2 standards, delivering arc-fault containment and maintenance-free performance for critical infrastructure systems.
