Product Description

The Eaton 500NHG3B-690 is a robust 690V circuit breaker designed for demanding industrial applications such as manufacturing, energy distribution, and infrastructure systems. As part of the 500NHG molded case breaker series, it features a three-pole configuration with a continuous current rating up to 630A and supports direct integration with modular accessories like shunt trips or under-voltage releases. It operates within a voltage range of 380–690V AC and functions reliably in temperatures from -25°C to 70°C. The breaker includes optional communication interfaces such as Ethernet/IP or Modbus TCP for remote monitoring. Key advantages include high interrupting capacity (up to 100kA), compact design for space-constrained installations, and compliance with IEC 60947-2 standards. It does not incorporate battery or display components, focusing solely on circuit protection. Typical applications include motor control, power distribution panels, and renewable energy systems requiring durable, high-voltage protection.
