Compact NSX for Direct Current

The Compact NSX DC range of Circuit breakers and switches is designed for DC voltages from 24 to 750 V and offers:

• A wide selection of models suited to many applications (1 to 4 poles up to 160 A, 2 poles from 630 A to 1200 A)
• High breaking capacities with four performance levels from 36 kA to 100 kA
• Fewer frame sizes: just two pole pitches (35 and 45 mm) for easy integration in installation systems (enclosure, machines, etc.)
• Accessories for insulation and series or parallel connection of pole, suited to the particularities of DC applications
• Fixed and withdrawable versions (3 and 4 poles, DC type)

The Compact NSX DC PV range includes circuit breakers and switch-disconnectors for photovoltaic applications with Voc up to 1000V (Compact NSX DC PV), equipped with a complete range of connection and insulation accessories (pole connections equipped with heat sinks, phase barriers, terminal shields):

• 4-pole circuit breakers for multi-array installation, isolating PV sub-arrays and protecting them from reverse current. Ratings from 80 to 500 A
• 4-pole switch-disconnectors for array isolation or as main switch. Ratings from 100 to 1500 A
