Rittal SV 9343.020 NH00 Fuse Switch Disconnector 160 A 3-pole 690 V AC

Fuse switch disconnector for NH00 fuse links, rated 160 A at 690 V AC, offering safe load breaking and isolation in a compact 3-pole design. Its robust construction with screw terminals and base mounting suits industrial power distribution, while the IP20 front cover protects against accidental contact.

Advantages

The Rittal SV 9343.020 combines high breaking capacity with reliable operation. The polyamide enclosure in RAL 7035 grey resists impact and provides insulation up to 1000 V. The switch disconnector accepts flexible conductors up to 70 mm² and rigid up to 95 mm², ensuring versatile wiring. The 8 kV impulse withstand rating and 50 kA short-circuit breaking capacity (with appropriate fuses) make it suitable for demanding networks.

Suitable for

• Industrial control panels and motor control centers
• Power distribution boards requiring NH00 fuse protection
• Busbar systems with 60 mm spacing
• Applications needing visible isolation and safe fuse replacement
