New Original Schneider 28904 Non-Automatic Switch-Disconnector
Product Overview
Schneider 28904 is a new original non-automatic load switch-disconnector under the Interpact INS series, with internal model INS80 3-pole configuration. It is a manually operated isolating switching device without automatic overcurrent or short-circuit tripping functions. Designed for low-voltage power distribution systems, this unit serves as a visible breaking point for circuit isolation, circuit switching, equipment maintenance safety lockout, and main incoming circuit control in control cabinets, distribution boxes, motor control loops and industrial automation equipment. It strictly complies with international isolation switch standards to guarantee electrical safety during offline maintenance work, and supports DIN rail mounting for compact cabinet layout arrangement.
Main Functions
- Manual ON/OFF switching for normal load current connection and disconnection, no automatic fault tripping mechanism.
- Provide obvious visible isolation break point to cut off power supply completely for equipment overhaul and maintenance, meeting safety isolation specifications.
- Mechanical interlock structure ensures handle position is consistent with actual contact status, preventing false state indication.
- Built-in padlockable handle design for lockout-tagout (LOTO) management to avoid accidental power closing during maintenance.
- Compatible with both top incoming wiring and bottom incoming wiring without current derating, flexible for various wiring schemes.
- Centralized control for branch circuits, motor local isolation, busbar connection switching and power distribution system section isolation.
