Overview
The Square D H-362 /D2 is a heavy-duty, fusible safety switch designed for industrial and commercial disconnect applications requiring maximum performance and service continuity. Heavy Duty Safety Switches are needed when maximum performance and continuity of service is essential for commercial and industrial applications. With a 60-ampere rating and 600VAC/VDC voltage rating, this H-362 /D2 switch provides reliable overcurrent and short-circuit protection when equipped with appropriate fuse types.
Key Features
- Quick-make, quick-break operating mechanism, dual cover interlock and color-coded indicator handle
- Equipped with fuses they can provide over-current and short-circuit protection
- UL listed with a NEMA 1 rating of protection
- Short circuit current rating of 10kA to 200kA; accepts H,J,K,L,R fuse types
- Surface-mounted configuration for quick installation
- Steel enclosure with visible blade contact design
