The Eaton Cutler-Hammer FD4225L is categorized as a molded case circuit breaker within the Series C line. It is engineered to deliver reliable protection and operates with a rated current of 225 A. The circuit breaker can handle voltage inputs of up to 600 VAC for alternating current and 250 VDC for direct current, making it versatile for various electrical systems.
As part of its construction, the FD4225L features an F-frame, designed to support robust applications. It includes four poles, which are essential for three-phase configurations. The trip mechanism is thermal-magnetic, effectively responding to both overload and short-circuit conditions.
This module provides significant protection and control, boasting different interrupting ratings depending on operating conditions. Specifically, at 240 VAC, it exhibits a 65 kAIC interrupting rating; at 480 VAC, the rating is 35 kAIC, and it maintains 18 kAIC at 600 VAC. Additionally, for applications using 250 VDC, it provides an interrupting capacity of 10 kAIC. This varying performance across multiple voltage ratings allows for a tailored response to specific system demands.
