Eaton PLHT-40-V miniature circuit breaker – 40A with 25 kA breaking capacity
The Eaton PLHT-40-V miniature circuit breaker (MCB) protects high-power circuits up to 40 amps. It offers a breaking capacity of 25 kA according to IEC/EN 60947-2. Therefore, it is designed for industrial applications and installations with high short-circuit currents. Use it wherever standard MCBs are insufficient.
The tripping characteristic is similar to characteristic curve D. This allows the switch to tolerate particularly high inrush currents. Consequently, you can use it for transformers, large motors, and welding equipment. Furthermore, it prevents false tripping during normal operating conditions.
Furthermore, energy limiting class 3 ensures minimized energy pass-through in the event of short circuits. Additionally, the rated insulation voltage of 440 V provides a high safety margin. This ensures comprehensive protection for your systems. Moreover, the high breaking capacity of 25 kA significantly exceeds that of the standard PLSM series at 10 kA.
The Eaton PLHT-40-V miniature circuit breaker is mounted on a DIN rail. It has a width of 27 mm and accepts conductor cross-sections from 2.5 to 50 mm², making it suitable for larger cable cross-sections. It can also be expanded with additional accessories.
