Molded Case Circuit Breaker for Line Protection
Thermal Derating and Ambient Performance
The breaker holds its full 250 A rating from 40 °C through 50 °C, then derates linearly to 200 A at 70 °C — a profile that suits enclosed switchgear or high-ambient machine rooms without oversizing. Maximum power loss is 48 W, which should be factored into the enclosure thermal budget, especially when multiple breakers are ganged.
Communication and Auxiliary Functions
This variant includes a communication function, allowing integration with higher-level control or monitoring systems — useful for remote load management or energy monitoring in a facility.
