Technical FAQs
Q1: What is the rated current of the Schneider NW25H1 Circuit Breaker?
The NW25H1 has a rated current of 2500 A at an ambient reference temperature of 40°C. It is designed for high-capacity low-voltage power distribution applications.
Q2: What does the H1 breaking-capacity classification mean?
H1 identifies the circuit breaker's breaking-performance class within the MasterPact NW range. For the NW25H1, the rated ultimate short-circuit breaking capacity is 65 kA at 440 V AC.
Q3: Is the NW25H1 suitable for three-phase electrical systems?
Yes. The three-pole configuration is intended for three-phase power distribution systems. The actual application must match the system's voltage, grounding arrangement, and protection requirements.
Q4: Can the NW25H1 operate at 690 V AC?
The NW25H1 has a rated operational voltage of up to 690 V AC at 50/60 Hz. Its breaking-capacity ratings must also be considered when selecting it for a particular voltage level.
Q5: Which protection units are compatible with the NW25H1?
The MasterPact NW25H1 platform supports compatible MicroLogic trip units. The specific control unit must be selected according to the breaker frame, electrical configuration, and required protection functions.
Q6: What is the difference between Icu and Ics?
Icu refers to the rated ultimate short-circuit breaking capacity, while Ics represents the rated service short-circuit breaking capacity. Both values are important when evaluating a circuit breaker's ability to interrupt fault currents and remain suitable for continued service.
Q7: Can the NW25H1 be integrated into an automatic transfer or power management system?
