Heavy-duty safety switches and fusible disconnect switches for irrigation pump stations and agricultural electrical systems. This collection covers EATON DH-series and HF-series safety switches in 2-pole and 3-pole configurations, fused and non-fused, rated for 600V service — the standard disconnect solution for irrigation pump motor installations requiring NEC-compliant lockable disconnects.
EATON DH-Series Heavy Duty Safety Switches — NEMA 3R rainproof enclosures for outdoor pump station use:
-
Fused 3-Pole (DH361FRK, DH362FRK, DH363FRK, DH364FRK, DH365FRK) — 30A through 400A, 600V. Standard fused disconnect for motor branch circuits.
-
Non-Fused 3-Pole (DH361URK, DH362URK, DH363URK, DH364URK) — 30A through 200A, 600V. For use where fusing is provided upstream.
-
Fused with Ground 3-Pole (DH361NRK, DH364NRK) — 30A and 200A, with ground lug. For systems requiring a grounded disconnect.
-
Fused 2-Pole (DH221NRK, DH222NRK) — 30A and 60A. For single-phase motor applications.
HF-Series Fusible Safety Switches — 30A through 200A (HF361R, HF361RL, HF362R, HF363R, HF364R). Standard fusible safety switches for pump motor disconnects.
To select the right switch, match the amperage to your motor's full-load amp rating (with appropriate safety margin) and confirm fused vs. non-fused based on your panel design. All switches feature visible blade disconnects and padlockable handles for lockout/tagout compliance.
