Eaton Three-Pole Reversing Drum Switch, Lever Operator, Oiltight

The Eaton Three-Pole Reversing Drum Switch is a maintained-and-momentary motor control device built without an overload relay, designed for direct-reversing control of three-phase motors. Operated by a lever, this oiltight switch supports flush or cavity mounting for clean integration into control panels and machine enclosures. Measuring 5.3 in in length/depth and 5.6 in in height, it delivers dependable, code-compliant switching for demanding industrial motor control applications.

Key Features

  • Three-Pole Configuration: Three-pole switching supports direct reversing control of three-phase motor circuits.
  • Lever Operator: A lever operator provides positive, easy-to-actuate control for maintained and momentary switching modes.
  • Maintained and Momentary Operation: Dual operating modes give installers flexibility for continuous-run or momentary jog control applications.
  • Oiltight Design: Oiltight construction helps protect internal contacts from oil, dust, and coolant exposure in machine-shop and industrial environments.
  • Flush or Cavity Mounting: Supports flush or cavity mounting for a clean, low-profile installation in control panels and enclosures.
  • Compact Footprint: Product dimensions of 5.3 in (length/depth) by 5.6 in (height) suit space-constrained panel layouts.
  • No Integral Overload Relay: Supplied without an overload relay, allowing pairing with separately specified motor protection where required.

Eaton 9441H276 – Frequently Asked Questions

1) Can an Eaton 9441H drum switch reverse a three-phase motor directly, without a contactor?
That is what it is built for. The 9441H is a three-pole reversing drum switch for direct-reversing control of three-phase motors, operated by a lever. It handles both maintained and momentary switching, so you can use it for continuous-run duty or for jog control off the same device. Note that it comes with no integral overload relay, so motor overload protection has to be specified separately in the circuit.
2) Does this Eaton drum switch include motor overload protection?
No. The 9441H reversing drum switch is supplied without an overload relay. It switches and reverses the motor only. You need a separate overload device, such as a starter or overload relay sized to the motor full-load amps, to protect the motor.
3) Will an Eaton 9441H drum switch hold up in a machine shop with coolant and oil spray?
Its housing is an oiltight design, which is specifically intended to keep oil, dust, and coolant off the internal contacts. That is the usual reason it gets specified on lathes, mills, and other shop equipment rather than an open drum switch.
4) How much panel space do I need for the Eaton 9441H drum switch?
Plan on a device measuring 5.3 in length/depth and 5.6 in height. Mounting is flush or cavity, oiltight, so the body sits behind the panel face with the lever out front. Lay out your enclosure depth against the 5.3 in figure before you cut the opening.
5) What is the difference between the DB 1 and DB 2 versions of the Eaton 9441H drum switch?
They are the two size selections on the 9441H reversing drum switch: DB 1 is Eaton part number 9441H276 and DB 2 is 9441H347. Order by that part number so you get the frame size your panel drawing calls for.
6) Is a drum switch the right choice, or should I use a reversing starter instead?
A drum switch like the Eaton 9441H is a manual device: the operator throws a lever and the contacts carry the motor current directly, with no coil, no pilot circuit, and no overload relay in the unit. That suits a machine where someone is standing at the control and reversing by hand. If you need remote pushbutton control, interlocking, low-voltage control wiring, or built-in overload protection, a magnetic reversing starter is the correct device instead.
7) Can I use the Eaton 9441H for jogging a machine as well as running it?
Yes, it is a maintained-and-momentary device. Held in a momentary position it jogs, and set to a maintained position it stays put for continuous run. That means one lever covers both setup jogging and normal operation on the same machine.
8) What compliance does the Eaton 9441H reversing drum switch carry?
It is listed as NLRV compliant. That is the only standard stated for the 9441H, so if your specification calls for another listing, verify it against Eaton's published data for the specific part number you are ordering.
