NH0, NH1-Fuse switch disconnector 250A 3NP1143-1BC11

NH0, NH1-Fuse switch disconnector 250A 3NP1143-1BC11 – Siemens – 4011209761476: Fuse switch disconnector NH1, 250 A 3NP1143-1BC11 Design as a safety switch, Max. rated operating voltage Ue at AC 690V, Rated uninterrupted current Iu 250A, Conditional rated short-circuit current Iq 80kA, Suitable for fuse links NH0, NH1, Number of poles 3, With fuse monitoring, Main circuit connection type Busbar connection, Other cable entry, Suitable for Busbar structure, design of the actuating element cover handle, position of the actuating element at the front, degree of protection (IP), on the front IP40, SENTRON, 3NP1 fuse switch disconnector, 3-pole, NH1, 250 A, for 8US busbar system 60mm, flat connection, fuse monitoring: electromechanical, cover level 32/70mm fuse switch disconnector 3NP up to 630 A with improved personal and system protection and convenient connection technology. The fuse switch disconnectors protect systems in industry or infrastructure from overload and short circuits and are suitable for cross-industry use. The reach-around and contact protection included as standard in the new Sentron 3NP1 series prevents the user from touching live parts when assembling busbar systems, even when accessing from the rear. In addition, the user can easily see the fuses used through the large viewing window. The main features of the Siemens 3NP fuse switch disconnectors are: 1. Extremely flexible thanks to the modular design and consistent accessories. 2. Suitable for floor mounting, DIN rail, and Siemens 8US busbar system 3. Electronic fuse monitoring function including mains monitoring. 4. Five sizes from 100 A to 630 A up to protection class IP40. 5. Faster and safer conversion for cable outlet above / below. 6. Flexible switching times of the auxiliary switch possible (simultaneously or ahead). 7. Possibility to lock and seal. For safe, efficient electrical infrastructure in buildings and industry, Siemens offers an integrated portfolio of protection, switching, measuring and monitoring devices, distribution boards, switches and socket outlets.
