AC/DC Solid State Motor Controls

Hubbell's S²MC Solid State Stepless Motor Controls are ideal for controlling overhauling loads such as lift bridges, bridge cranes, bucket/grapple cranes, portal/whirly cranes, turbine cranes, tramways, and coke oven drives.

Utilizing AC induction motors (squirrel cage and wound rotor) the line of S²MC controllers are available in both primary thyristor (4920 series) and secondary thyristor (4940 series) through 500 hp, or more, and capable of operating on 208/230/380/460/575, 3 phase VAC, 50/60 Hz.  The line of S²MC controls have been successfully applied on hundreds of applications for over 15 years.

Disconnect Switch

Type 4245

The Manual-Magnetic Disconnect Switches are combinations manually and magnetically operated contactors enclosed in a NEMA Type wall-mounted enclosure

The contactors for the disconnect switches are the same as the contactors used on Euclid's crane and mill type magnetic controllers.  Silver faced contacts are standard.

Type 5410

Fused Disconnect - Rated 30amp-200amp. UL Listed.

Electronic Components

The Bulletin 5330 Electronic Frequency Relay (EFR) master/slave system is designed to be used with wound rotor motor controls.  The master unit is a complete frequency relay providing one point of frequency detection. The master relay can be used as a stand-alone relay. The slave unit must be used with the master unit and provides additional points of frequency detection.

The Bulletin 5350 Static In-Line Timer is a solid state timing unit for use in AC or DC contactor and relay control. The timing unit is a series control element having an adjustable timing range. Two units are available. One with a timing range of 0.5 to 3.0 seconds, another with a timing range of 2.5 to 16.0 seconds.

The Bulletin 5360, Hubbell Arc Suppressor, is designed to reduce contact arcing in DC control circuits where the inductive coil loads of contactors and relays are interrupted.  Utilization of the Bulletin 5360 Arc Suppressor may eliminate the use of an interposing relay.

The Bulletin 5370 Electronic Overload Relay receives line current signals from an ammeter shunt and performs both the Inverse Time as well as the instantaneous Trip functions normally performed by two (2) separate electro-mechanical overload relays.

Limit Switch

Type 4220

D-C Limit Switches are devices that are used to interrupt the main power circuit, setting up a dynamic braking circuit that quickly stops hook travel with a minimum of drift.


A-C Limit Switches are similar in construction to D-C Limit Switches.  The difference is in operation.  A-C Limit Switches disconnect two power lines to the hoist motor which then is stopped by a magnetic brake.

Type 4225

Euclid quick break limit switches for hoists are normally closed by the weight of the striking lever.  The movement of the lever on its upward travel, when engaged by the hoist hook block on its upward travel, causes the switch to quickly break the circuit to the motor with very little upward movement of the crane hook.  The switch is automatically reset by the weight of the striking lever when the hook is lowered.

Master Switch/Drum Controller

Type 4211 Mini-Master

The Euclid Mini-Master Switch uses a handle operated cam switch mechanism in a NEMA rated housing.  It is engineered for use where master switch control is preferred, for CMAA duty overhead crane and similar applications.

Type 4216 Mill Master

These master switches are of rugged construction to withstand the rough service encountered on applications in the steel mills, such as crane, coal, and ore bridges, blooming and rolling mill auxiliaries, etc., where either floor or desk mounting is required

Type 4253

Furnas Brand Master Switches are used to provide single handle pilot control of hoists, cranes, oven pushers, car movers and other equipment requiring speed steps of wound rotor or direct current motors.

Type 4258

Furnas Brand Drum Controllers start, stop and change the speed and/or rotating direction of reversible AC and DC electric motors.
