Disconnect Switches
Heavy-duty and general-duty safety switches, fusible and non-fusible, 30 to 1200 A, NEMA 1 through 4X, new, surplus, and obsolete.
Edmundson Industrial sources disconnect switches, also called safety switches, across the full range: fusible and non-fusible, heavy-duty and general-duty, single- and double-throw, from 30 A through 1200 A and 240 V to 600 V. Send the catalog number, or the ampere rating, poles, voltage, fusible or non-fusible, and enclosure, and we quote availability, condition, and lead time.
Types we source
| Type | Notes |
|---|---|
| Fusible | Switch plus fuses (Class H / J / R): provides overcurrent protection |
| Non-fusible | Switch only: isolation and lockout, no fusing |
| Heavy-duty (HD) | 240–600 V, higher endurance, industrial duty |
| General-duty (GD) | 240 V, light commercial and light industrial |
| Double-throw | Manual transfer between two sources |
| NEMA enclosures | Type 1 indoor, 3R rainproof, 4 / 4X watertight / stainless, 12 dust-tight |
Brands we source & cross-reference
How do you specify a disconnect?
- Ampere rating (30, 60, 100, 200, 400, 600, 800, 1200 A)
- Poles and voltage (2- or 3-pole; 240 or 600 V; AC or DC)
- Fusible or non-fusible (and fuse class if fusible)
- Enclosure / NEMA type for the environment
- Horsepower rating if switching a motor
Square D heavy-duty switches read like H361 (fusible, 30 A, 600 V) or HU361 (non-fusible); Eaton heavy-duty switches read like DH361. Send the catalog number and we confirm the build.
How do we quote a disconnect switch?
- Send the catalog number (for example H361 or DH362), or the ampere rating, poles, and voltage.
- We confirm fusible or non-fusible, enclosure (NEMA type), and HP rating.
- We quote condition, price, and lead time: new, surplus, or used-tested, timing confirmed with the request.
- Need a custom enclosure, back-panel, or mounting? Our fabrication side builds and modifies enclosures to fit.
