Eaton Heinemann GJ2H99H63W Circuit Breaker

Eaton Heinemann GJ2H99H63W is a 2-pole circuit breaker rated for 150 A at 125–250 VDC. The device is designed to interrupt direct current to protect connected circuits from overcurrent conditions. The 125–250 VDC rating indicates it can be used in DC systems operating anywhere within that voltage window, making it suitable for equipment and installations that require DC overcurrent protection. The model number GJ2H99H63W serves as the precise identifier for ordering, sourcing, and maintenance records, ensuring you select the exact replacement part. This breaker’s dual-pole arrangement protects two conductors in a single device for DC applications that require overcurrent protection. Its 150 A rating defines the maximum continuous current before trip under specified conditions, while the 125–250 VDC range defines the voltage window for which the device is intended. Because it is identified by the GJ2H99H63W part number, refer to it in technical documentation and catalogs to confirm compatibility with Eaton Heinemann offerings.
