Industrial Motor Disconnect Switch

The Hubbell HBLDS33ACNK is a non-fused motor disconnect switch built for industrial electrical systems. It isolates power to motors so maintenance can proceed without accidental restart. Rated for heavy-duty service, it suits professionals who need reliable lockout capability in demanding environments.

3PST 30 A 600 V Contact Form

The switch uses a three-pole single-throw configuration rated at 30 amperes and 600 volts AC. This contact arrangement controls three circuits simultaneously, making it the decisive specification for three-phase motor applications that require full disconnection.

15 HP Motor Capacity and NEMA 4X Protection

At 600 V AC the switch handles motors up to 15 horsepower, covering many standard industrial drives. The non-metallic NEMA 4X enclosure resists dust, water, corrosion and external ice formation, so the unit remains operational in wash-down and outdoor settings.
