The Eaton Cutler-Hammer KD3225W is classified as a molded case circuit breaker, providing essential protection in electrical systems. Rated at 225 Amperes, this breaker consists of three poles, making it suitable for managing multiple circuits efficiently. The device is built to operate within high voltage ratings of up to 600 VAC for alternating current and a maximum of 250 VDC for direct current systems.
A significant feature of the KD3225W is its high interrupt ratings, enhancing its reliability when dealing with short circuits. It boasts an interrupt rating of 65 kAIC at 240V AC, which is effective for applications requiring substantial fault current management. At 480V AC, it maintains a 35 kAIC interrupt capacity, and at 600V AC, its rating is 25 kAIC, indicating its capability to handle severe surges.
In terms of operational characteristics, the KD3225W uses a fixed thermal and fixed magnetic trip mechanism, ensuring prompt response to overloads and short circuits. The K-Frame size indicates that it is a compact and efficient choice for utility installations.
This circuit breaker functions across a frequency range of 50 Hz to 60 Hz, accommodating various electrical systems while maintaining functionality. Additionally, its design is focused on combining performance and safety in demanding settings, making it a favorable option for modern electrical installations.
