Eaton Cutler-Hammer produces the CHB340, a thermal magnetic circuit breaker characterized by its reliable performance and robust design. This part is rated for a maximum of 40 amperes and operates effectively at 240 VAC. Efficiency in operation is enhanced through its three-pole configuration, earmarking it for three-phase systems.
The device is engineered to handle an interrupt rating of 10 KAIC. This feature ensures it can safely manage fault conditions without compromising safety or performance. Users must adhere to specific wire sizes, with compatibility for #8 to #4 AWG cables, which facilitates flexibility in installation.
Temperature tolerances are crucial for circuit breakers; the CHB340 operates optimally in an environment between 0°C and 40°C, encompassing both operational and storage conditions. This capability highlights its suitability for both controlled and outdoor applications, where temperature variations may occur.
