Schneider Electric 33443 ComPacT NS800NA 4P Switch-Disconnector - Fixed Electrically Operated
800A Frame | 4P
Part number 33443 identifies the ComPacT NS800NA switch-disconnector rated at 800A in a 4-pole configuration. This basic frame, fixed-mount and electrically operated, is designed for safe isolation and disconnection of electrical circuits in accordance with IEC 60947-3 standards. Unlike circuit breakers, switch-disconnectors provide no automatic overcurrent protection but ensure positive contact indication and padlockable isolation for maintenance safety. With a rated insulation voltage of 1000V and rated impulse withstand of 8kV, the NS800NA ensures robust dielectric performance. The device is certified for pollution degree 3 industrial environments with IP40 protection and complies with IEC 60947-3 standards for switches, disconnectors, and switch-disconnectors. Physical dimensions of 327 x 280 x 147 mm enable efficient integration into switchboard assemblies. Part of the Schneider Electric ComPacT NS new generation range, the NS800NA is suitable for main incoming isolation, bus-section switching, and maintenance disconnection in commercial buildings, manufacturing plants, and infrastructure installations. The 33443 features class II front-face protection for installation in class II switchboards without downgrading insulation. Green Premium ecolabel certified for environmental compliance with RoHS and REACh directives. Compatible with the full range of ComPacT NS accessories including rotary handles, voltage releases, and indication contacts for complete system integration. The padlockable toggle mechanism accepts up to three padlocks for multi-person lockout/tagout procedures, ensuring compliance with workplace safety regulations during maintenance activities.
