30 mm 4-Position Selector Switch

The unit carries CSA certification and UL listing for compliance with North American safety standards.

Panel cutout and NEMA rating check

Verify that your enclosure provides a standard 30 mm cutout for mounting this operator. The switch carries NEMA ratings 1, 3, 3R, 4, 4X, 12 and 13, so confirm the enclosure’s own rating matches the environmental protection required for your application. No key removal or locking mechanism is present on this model.

Thermals noise and power draw

As a mechanical selector operator, the device generates no heat and produces no audible noise during normal switching. It draws no electrical power itself; power consumption depends entirely on the contact blocks and load circuits installed behind the operator. The extended lever provides positive tactile feedback across all four maintained positions.

Questions about this item

What comes with the 52SB2HAB selector switch and what must be purchased separately?

The package contains the non-illuminated 30 mm selector switch operator with extended lever and cam H. Contact blocks, mounting hardware and legend plates are not included and must be ordered separately.

How do I choose between the available versions of this 4-position switch?

The 52SB2HAB is a single configuration: 4-position maintained action, black extended lever, cam H, NEMA 1/3/3R/4/4X/12/13 and CSA/UL listed. No alternative versions are offered for this part number.

What does the NEMA 4X rating mean when the switch is installed in a real enclosure?

NEMA 4X certifies the operator withstands hose-directed water, splashing and corrosion when properly mounted in a compatible enclosure; it does not guarantee the complete assembly meets the rating without matching gaskets and fittings.
