Mitsubishi Electric NV250-CV Residual Current Circuit Breaker 3P 250A 2-440V
1. Product Positioning
The NV250-CV is a cost-effective (NV-C TYPE) residual current circuit breaker (ELCB) in Mitsubishi Electric's WS-V series. It is designed to provide cost-effective integrated overload, short-circuit, and leakage protection for power distribution systems up to 250 A. With international certifications such as CCC and CE, it strikes a balance between performance and cost, making it an ideal choice for OEM panels, commercial buildings, and light industrial power distribution.
2. Key Selling Points
• High interruption rate and economical practicality
– Icu/Ics: 25 kA / 19 kA @ 400 V, sufficient to meet the short-circuit capacity requirements of most secondary distribution systems.
• Adjustable leakage protection
– 30 mA high sensitivity or three adjustable settings of 100/200/500 mA ensure a balanced balance between personal protection and equipment leakage current tolerance.
• Thermal-Magnetic Dual Protection
– Thermal tripping accurately responds to overloads, while electromagnetic tripping instantly interrupts short circuits. The operating characteristics are stable and maintenance-free.
• Wide Voltage Coverage
– Universally compatible with 100–440 V AC, the same model is compatible with 230 V and 400 V systems, reducing model inventory.
• Compact 250 Frame
– The 3P circuit breaker is only 105 mm wide, saving over 20% cabinet space compared to traditional 250 AF circuit breakers.
• Long Mechanical Life
– 8,000 mechanical cycles and 4,000 electrical cycles reduce replacement frequency and downtime costs.
• Comprehensive Certifications
– Compliant with IEC/EN 60947-2 and GB/T 14048.2, and certified by CCC and CE, ensuring worry-free export projects.
3. Technical Parameters
• Rated current In: 125 A, 150 A, 175 A, 200 A, 225 A, 250 A
• Number of poles: 3P (standard); 4P requires the NV250-SV/HV series
• Rated operational voltage Ue: AC 230/400/415/440 V
• Rated impulse withstand voltage Uimp: 6 kV
• Rated ultimate/service short-circuit breaking capacity Icu/Ics: 25 kA / 19 kA @ 400 V
• Rated earth leakage operating current IΔn: 30 mA (fixed) or 100/200/500 mA (adjustable)
• Operating type: Type A (pulsating DC sensitive)
• Overcurrent release: Thermal-magnetic
• Selectivity category: Type A
• Mechanical life: 8,000 =Times; Electrical Life: 4,000 cycles
• Operating Temperature: –25°C … +60°C
• Protection Rating: IP20 (terminals), IP40 (with front cover attached)
• Dimensions (3P): W 105 × H 165 × D 92 mm
• Weight: ≈ 1.7 kg
4. Typical Application Scenarios
• Floor distribution boxes in commercial complexes
• Power cabinets in light industrial plants
• Data center terminal distribution
• Lighting and air conditioning circuits in hospitals, schools, and hotels
• OEM complete set export projects (CE certification required)
