Alternating Relay Type 5247
 |
The Class 47 alternator relay provides a means of automatically alternating the operation of two separately mounted motor driven pumps or
compressors. This alternating action assures even readiness and wear on both pumps.
The Class 47 alternator is of industrial design specifically for use in pump and compressor applications. It is easily field installed and
wired in control panels, pump panels or as a separately enclosed unit for surface mounting.
The alternator has single pole double throw heavy duty 10 ampere silver cadmium oxide contacts enclosed in a transparent dust cover. The
snap action contacts transfer when the unit is de-energized. The circuit is never closed or opened while current is being conducted. This
provides increased control life. The alternator is wired to operate the second motor starter the next time a pump operation is required.

Relay
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.

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:
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:
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.

Resistor
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.

Radio Control Products
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.
