Industrial Disconnect Switch

The Hubbell HBLMITL is a non-fusible disconnect switch rated for 30 A with a 3PST contact form. It is built for heavy-duty industrial use in manufacturing, construction and energy production environments. The switch provides a means to interrupt electrical current for maintenance, repair or emergency stoppage. Its enclosure carries NEMA 12K, 4 and 4X ratings for protection against dust, water and corrosion.

30 A Current Rating

The decisive specification is the 30 A ampere rating which defines the maximum current the switch can safely interrupt. Compatibility testing covers manufacturer model numbers VLS3P016D1, VLS3P025D1, VLS3P032D1 and VLS3P040D1, though integration should be verified. The heavy-duty classification confirms suitability for demanding, frequent operation cycles in industrial settings.

For Industrial Maintenance Teams

This switch suits facilities needing a robust, non-fusible means of isolation for 30 A three-pole circuits. It is not intended for applications requiring fused protection or for lower-current control panels that need a different contact configuration. Buyers who need integrated overcurrent protection or a different pole arrangement should look at alternative devices.

Questions about this item

What does the 30 A rating mean once the switch is installed in a panel?

It means the switch is designed to carry up to 30 amperes continuously in normal operation, so the circuit it controls must not exceed that current.

How does the NEMA 12K, 4 and 4X enclosure rating limit where this switch can be mounted?

The rating certifies the enclosure against dust, falling dirt, dripping water, hose-directed water and corrosion, so it can be installed indoors or outdoors in wet or wash-down areas.

What mounting provisions does the HBLMITL require to fit in an enclosure?

The switch is built for panel or enclosure mounting with standard hardware; the 3PST contact block and heavy-duty construction fit NEMA 12K, 4 and 4X rated enclosures.
