Overview
The GE 730049 Dilos 1 load-break switch disconnector is a DIN-rail mounted, 3-pole disconnect switch designed for industrial electrical distribution and control applications. With a 40A rated current, padlockable rotary handle, and dual-knife contact design, the 730049 provides reliable load-break operation and meets international safety and performance standards for low-voltage installations up to 690V.
Key Features
- Rated current: 40A with padlockable rotary handle for safety lockout
- Three-pole (3P) configuration for three-phase applications
- Double-knife contacts for high short-circuit resistance and reliability
- Quick-make, quick-break mechanism for positive contact indication (PCI)
- Independent opening and closing mechanism
- Visible contact indication for safe operation confirmation
- DIN-rail mounting for compact industrial panel integration
