Designed for both protection and performance, the Eaton Cutler-Hammer GHQRD2020 dual-purpose circuit breaker manages a current load of 20 A. It operates at voltage levels of 277/480 V AC, making it suitable for a range of electrical systems. With a robust thermal-magnetic protection mechanism, this circuit breaker is engineered to react effectively to overloads and short circuits.
The GHQRD2020 consists of two poles, allowing for a variety of configurations in industrial applications. Rated for 50/60 Hz operation, it can handle up to 14,000 amperes under 277/480 V AC conditions. Impressively, it provides an interrupting capacity of 65,000 A at both 120 V and 120/240 V, ensuring safety amidst electrical disturbances.
This model uses remote solenoid operation through a 24 V DC system, enabling effective control of the circuit breaker. The control signal can be either rectified AC or half-rectified AC, giving flexibility in installation. Mounting is performed via a bolt-on mechanism, and connections are made using line-side lugs, promoting secure and efficient assembly.
