Hubbell Incorporated HBL7852D Manual Motor Switch 50 A 2 P 1 Phase

Manual Motor Switch 50 A 2 P

The Hubbell HBL7852D is a single-gang manual motor switch rated for 50 amps and two poles in a single-phase configuration. It suits industrial or commercial installations that need a simple toggle operator to disconnect motor circuits. The transparent housing allows visual confirmation of the switch position during routine checks.

Build and mounting implications

The toggle operator provides direct, tactile control without a pilot light, so status is confirmed by feel and sight rather than an indicator. With a two-pole design it breaks both legs of a single-phase supply, which is standard for motor disconnects in this class. The transparent enclosure lets maintenance staff verify contact state without removing covers.

Practical limits of the rating

The switch is rated for 2 hp at 120 V AC and 5 hp at 240 V AC on single-phase supplies. It carries no horsepower rating for three-phase systems at 208 V, 240 V, 480 V or 600 V, so it cannot be used as a three-phase motor disconnect. Installations requiring three-phase switching must select a different device.
