FAQ

Q: What is the difference between a DC circuit breaker and an AC circuit breaker?

A: DC current lacks a natural zero-crossing point, making arc extinction difficult. Consequently, DC circuit breakers require higher standards regarding arc-extinguishing structures, breaking speed, and energy absorption capabilities.

Q: Does the DC 250A Mould Case Circuit Breaker support remote monitoring and intelligent interlocking?

A: This circuit breaker offers an optional intelligent module that supports an RS485 communication interface and the Modbus protocol. This enables remote status monitoring, fault alarming, and switching control, making it ideal for building intelligent DC power distribution systems.

Q: Is derating required when using the DC 250A MCCB in high-altitude regions?

A: The XENHO DC 250A Mould Case Circuit has been specifically optimized for high-altitude environments; it requires no derating at altitudes up to 5,000 meters. Its insulation performance and breaking capacity remain reliable, making it particularly suitable for high-altitude PV and energy storage projects in western regions.

Q: How does the product perform in extreme temperature environments?

A: The product operates stably across an extreme temperature range of -40°C to +85°C. Its critical internal materials and contact structures undergo special treatment to effectively resist low-temperature embrittlement and high-temperature aging, ensuring excellent performance is maintained even in harsh environments such as frigid plateaus or scorching deserts.
