|WEG Electric Miniature Contactors (3-Pole & 4-Pole)|
CWC series mini contactors are a complete solution for controlling motors and switching other loads. The CWC's compact dimensions for its IEC current rating, up to 22A, AC-3 utilization category, allows it to take up less space inside electrical enclosures while still offering up to a powerful 15hp @460V. WEG RW series overload relays are available in compact frame sizes from 0.28A to 32A and are designed for use with, and as perfect complement to, the CWC miniature contactors.
- 7, 9, 12, 16, 22 Amp 3-pole models
- 7, 9, 16 Amp 4-pole models
- Matching direct mount overload relays
- Available auxiliary contact blocks, surge suppressors, Star-Delta electronic timing relays, wiring kits, and mechanical interlock and latch blocks
|Motor Failure Relays|
Phase monitor relays provide protection against premature equipment failure caused by voltage faults on 3-Phase systems. All ProSense 3 phase monitor relays are designed to be compatible with typical Wye or Delta systems. Phase monitoring relays protect against single phasing regardless of any regenerative voltages.
Alternating relays are used for motor load control in special applications where the optimization of load usage is required by equalizing the run time of two loads. The alternating action is initiated by a control switch, such as a float switch, manual switch, timing delay, pressure switch, or other isolated contact. Each time the initiating switch is opened, the output relay contacts will change state, thus alternating the two loads.
Pump failure relays are designed to monitor the shaft seals of submersible pumps. A resistive-measuring probe provided by the pump manufacturer is installed in the pump seal cavity. If the pump seal starts to leak, contaminating fluid enters the seal cavity, lowering the resistance between the internal probe and the common connection. When the resistance drops below the user-adjustable sensitivity setpoint of the relay, the output relay energizes.
|Fuji 3-Pole Contactors|
The DUO line (SC-E contactors and TK-E overloads) is fully integrated so multiple motor speed controller solutions are possible with a minimum number of components. The conventional motor starters in the DUO line can accommodate electric motors up to 75kw (100hp )at 480 VAC. The larger motor contactors feature the SUPERMAGNET coil for greater reliability and positive pick-up and drop-out.
Now ... 440-480 VAC and 500-550 VAC Coil Voltages are available also.
The Odyssey Series of contactors and overload relays also features the SUPERMAGNET coil and come in sizes up to 361 A, AC-3 operation 22kw (300hp) at 480 VAC. Odyssey Series contactors are available in four sizes with overload relays to match any motor to 225kw.
Now ... 380-450 VAC and 460-575 VAC Coil Voltages
Both the DUO and Odyssey lines are available in 24 VAC, 24 VDC, 120 VAC, 240 VAC, 380-575 VAC. The motor contactors are rated up to 690 VAC, 3-phase.
|Manual Motor Starters|
The Fuji Duo Series Manual Motor Starter is a protective device for electric motor use that provides optimal protection by integrating the functions of a molded case circuit breaker and thermal overload relay into a compact unit. Since Fujis MMS is UL listed for Category E self-protected motor control, it can be used for motor branch circuit protection without the need for additional protection such as fuses or molded case circuit breakers.
The Manual Motor Starter (MMS) is available in a 32A version with a 45mm frame width, and a 63A version with a 55 mm frame width.
Both MMS versions have high breaking capacities, up to 100,000A in some ranges. A wide range of accessories is available, including shunt trips and undervoltage releases.
|Low-Cost Basic Series|
The GH series of IEC contactors and bimetallic overload relays are manufactured by Europes leading maritime contactor company. Contactors for ocean-going vessels are built to the most rigid specifications. This same design technology carries over to this line of industrial electric motor controls.
We offer individual components that allow you to use the contactor alone or to assemble your motor starter using our thermal overload relays. You can also combine a manual motor starter/protector for all-in-one protection.
Use contactors wherever you need a heavy-duty switching device with up to three poles. Add up to eight auxiliary contact blocks for interlocks and feedback. Or, use the optional mechanical interlock to create an inexpensive reversing contactor.
|Manual Motor Switches|
Bryant has designed a compact motor controller that will also meet the rigorous demands of a motor disconnect. Bryants motor controllers are listed as "Suitable as Motor Disconnect" under UL Standard 508 Industrial Control Equipment qualifying them to perform both operations in one compact package. By utilizing Bryants compact motor controllers and motor disconnects, you benefit through the convenience of one device fulfilling two needs. AutomationDirect offers three versions of manual motor controllers (MMCs) and industrial motor disconnects:
- Toggle Switch AC Motor Controllers
- Enclosed Toggle Switch AC Motor Controllers
- Enclosed NEMA 4X Rotary Switch AC Motor Controllers
