Cut-in (close the contacts) on rising air or water pressure. Designed to ground ignition on gas driven pumps and compressors when
desired maximum pressure is reached. Can also act as low pressure alarm or to prevent pump operation at low pressure. Reset lever optional.
Wired in series with a conventional Hubbell pressure switch. When failure of the water or air supply causes system pressure to fall
considerably below the cut-in point of the regular pressure switch, the GARD-IT will disconnect the pump motor. When the water or air
supply returns, the system is placed in automatic operation by depressing the manual reset lever until system pressure exceeds the
GARD-IT cut off level.
Wired in series with any system pressure, this special pressure switch is designed to cut-out (open the contacts) when a preset pressure
is reached. Must be manually reset. HI-GARD pressure switch is used when it is desirable to limit the maximum pressure in a system.
Hubbell Euclid Magnet Controllers utilize heavy duty components and circuitry arranged to provide optimum control of your lifting magnet.
Full featured NEMA Type 1 or 3R enclosed magnet controllers are available for immediate shipment. Of course, we welcome inquiries for
custom applications as well.
The latest addition to the Hubbell Industrial Controls family are DC Devices used in solid-state adjustable speed drives, uninterruptable
power supplies, fuel cells, crane controls, transit and rail vehicles, gas and oil well drilling equipment, mining machinery, and more.
These devices are ideal for a wide range of heavy duty applications.
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 Bulletin 5350 Static In-Line Timer is a solid state timing unit for use in AC or DC contactor and relay control.
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.
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.
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.
Rugged Euclid contactors feature many unique design and engineering advancements that greatly simplify applications, installations and
servicing. Over 65 years of experience in design as well as manufacturing has been incorporated into these highly reliable units.
DC Relays, Type 5320, general purpose control, voltage sensitive, current, and plugging relays are built to withstand severe service
using the latest technology in materials for insulating and high-strength. They are recommended for use on heavy industry dc drives
such as cranes and mill auxiliaries.
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.
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.
Drum Controllers start, stop and change the speed and/or rotating direction of reversible AC and DC electric motors.
Class 5010 Type F: Magnetic drum brakes are spring set, electrically released, drum type friction brakes which are used with either AC or DC motors, used as holding brakes on DC series motor drives, crane hoists, mill drives, and transfer cars.
Class 5060 Type AT: Adjustable torque brakes are dual-purpose, drum-type friction brakes that combine an electrically released, spring-set holding brake with an electrically operated, adjustable torque stopping brake within one brake frame.
Class 5010 Brake Rectifier: Converts AC line power to DC for use with a rectifier operated brake. A high speed forcing circuit provides optimum operation of the brake.
LED Bridge Crane Lighting: The HBLC LED Highbay is specifically designed to be used on heavy industrial bridge cranes while utilizing AC or DC input voltage. Custom engineered LED optics provide evenly distributed light for bridge crane operators and others working under the crane for increased visibility and safety.
HD stations of heavy duty steel or aluminum may be pendant or surface mounted. They are shipped fully assembled and ready for
PBC, WPBC, and XPBC are cam operated stations assembled in a variety of enclosure types. These stations are available with special
circuit configuration and can be from one to five speeds, stepped or stepless operation. Many options are available for this type
of station, including duplex construction with conduit boxes selector switches and many other special features.
Hubbell Type SSR Power resistors from 1.3 amps through 101 amps are available, from unassembled to completely assembled in frames with
covers. Standard assemblies are pre-engineered for primary or secondary resistance, and are used in typical applications such as motor
starting or dynamic braking. Construction elements are stainless steel around a porcelain insulator, manufactured for endurance and reliability.
Heavy duty Types K1 and HHC resistors also utilize continuous stainless steel elements, with no weld joints where hot spots could develop.
These resistors are available in ranges from 38 amps to 695 amps.
Hubbell pressure switches provide automatic control for air or water systems such as compressors, dry sprinkler systems, and well pumps or
pumping systems. Thousands of variations are available to provide maximum flexibility at minimum cost.
Speed responsive switches detect motion, or sense over-speed or under-speed occurrences of industrial machinery or motors. Hubbell
Industrial Controls, Inc. has both direct coupled or non-contact type switches for; directional, non-directional, plugging, anti-plugging,
over-speed, under-speed, and also zero-speed applications. Many enclosure styles are available including surface or flange mounting with
NEMA 3, 4, 7, 9, 10 or 13 construction.
A typical radio remote control system consists of a portable transmitter carried by the operator, and a receiver installed on the crane,
the locomotive, or other remote machinery. Each system operates on a licensed frequency in the 72 to 76 MHz or the 450 to 470 MHz bands,
requiring the user to have an FCC license for the transmitter.
