Application
Class 14 industrial magnetic starters are designed for
ESP100 starters combine the rugged characteristics of a NEMA rated contac- tor with a solid state overload which provides phase loss protection. It offers the industrial user greater protection and added life for motors in heavy duty applications. The inherent benefits of the ESP100 result in cost savings as well.
Starter with thermal overload relays (together with the proper heater ele- ments) help provide protection to motor windings from harmful currents and the resultant temperature rise that may be caused by overloading the motor, sus- tained low line voltage, or stalled rotor.
Size
With Melting Alloy Overload
These controls are available in NEMA sizes 00 through 6. ESP100 starters are available in NEMA sizes 0 through 6. In addition to the usual NEMA starter sizes, four exclusive Half
Across the line or full voltage starting is used when motor starting torque can be applied safely and current inrush does not produce an objectional voltage drop. All starters are supplied with a NO hold- ing contact that in conjunction with an appropriate pilot device will provide low voltage protection or release.
Features
Size
Molded Coil — Magnetic coils are care- fully wound and then sealed in epoxy. Encapsulation helps seal out moisture, promotes heat transfer, and resists elec- trical, mechanical, and thermal stresses.
Dual Voltage / Dual Frequency Coil — Starters are available with dual voltage, dual frequency coils. They are designed to operate on either 50 or 60 Hertz.
ESP100 Solid State Overload Relays — These standard features of the ESP100 provide Extra Starter Performance.
JTrue phase loss protection; trips within 3 seconds.
JHigh accuracy trip curves; ±2% repeat trip accuracy.
JEase of use. Mount, wire and set FLA.
JOverload is self protected against short circuits.
Size
With Bimetal Overload
JOverload is self powered and requires no hard wiring or separate power source.
JSimple, versatile adjustment; over a 2:1 FLA adjustment range. Extendable to 4:1 with looping option.
JHeaterless construction minimizes energy costs and the costs of cabinet ventilation or cooling.
JClass 20 protection is standard. Class 10 and 30 protection are available.
JProvides motor protection to 50 / 60 Hertz.
Thermal Overload Relays — Melting alloy is supplied as standard; optional bimetal overload relay is available.
Ambient compensated bimetal version is also available. Bimetal types are convert- ible from manual to automatic reset and can be furnished with standard or quick trip heater elements. Melting alloy over- loads include a trip indicator and manual test feature. An isolated normally open or normally closed contact is available for
use on melting alloy overloads. Bimetal 15 overloads are also available with NC and
NO (SPDT) Form C contacts.
