    23. Overload Relays What is the Difference: Between A Short Circuit & An Overload ?

    24. Overload Relays What Is A Short Circuit? An Extreme Amount Of Current Usually Caused By A Fault To Another Phase Or To Ground. Fault Currents Can Exceed Several Thousand Amps For A Very Short Period Of Time Which Can Cause Very Extensive Equipment Damage. Fault Currents May Even Reach Up To 200,000 Amps On Some Systems.

    25. Overload Relays What Is An Overload? 1. An Operating Condition Where The Load Current Exceeds Normal Operation. 2. A Motor That Is Overloaded May Draw 6 Times Its Normal Operating Current (Full Load Current). 3. An Overload For Even Several Minutes May Cause Severe Motor Damage.

    26. Overload Relays What Are The Differences Between … A Fuse Or A Circuit Breaker And An Overload Relay?

    27. Overload Relays Short Circuit Protection Devices Fuses - One Time Use Only Magnetic Circuit Breakers - Reusable After Reset Overload Protection Devices Time Delay Fuses -One Time Use Only Overload Relays - Able To Reset Thermal Magnetic Circuit Breakers - Also Able To Reset

    64. ESP100 Electronic OLR True phase loss protection Overload trips within 3 seconds on phase loss, even on lightly loaded motors (60% of minimum dial setting) Customer Benefit: Saves Motors!!! Thermal overloads just can’t provide this degree of protection

    65. Electronic OLR Heaterless Construction No heaters to install, stock, or maintain Customer Benefit: Heaters require time and labor to install

    66. ESP Self - Powered Generates its own low voltage control power through the same sensors that read motor current Customer Benefit: Separate 120VAC control power is not required

    67. ESP100 OLR Ambient Insensitive Overload not affected by temperature, rated -30 °C to 70 °C Customer Benefit: No nuisance tripping on hot days. No open panel doors with fans blowing on controls.

    68. ESP100 OLR 99% of heat generated by thermal overload removed Customer Benefit: Other electronic equipment in panel runs cooler, energy savings. More equipment could go into panel due to lower heat rise.

    69. ESP100 OLR Energy Savings Thermal overloads generate 9 to 24 watts per relay Based on 10 watts per overload and $0.10 per kW/hr, ESP100 will save $7.88 per year in energy costs This can really be significant if user has hundreds of starters!!!

    70. ESP100 ORL Self protected from short circuits Upon the event of a short circuit, the current transformers saturate before any damage is done to the overload Customer Benefit: No need to replace overload relay or heater elements after a short circuit as is required with thermal overloads

    71. ESP100 OLR ± 2 % repeat accuracy Customer Benefit: Under the same conditions, trip time on the overload will be the same within ± 2%

    72. ESP100 OLR Circuit boards have conformal coating on them. Customer Benefit: Rugged design that will hold up in humid, corrosive environments

    73. ESP100 OLR No two labels are the same Every ESP100 overload is individually calibrated and a custom label is printed for that overload. Customer Benefit: Superior accuracy of dial setting - no competitor does this!

    74. ESP100 OLR Thermal Memory “Remembers” the heat buildup in hot or overloaded motors Customer Benefit: Trips faster on a restart since the motor windings are hot

    75. ESP100 OLR Simple Installation Mount it, wire it, dial in FLA Customer Benefit Fewer connections, saves installation time

    76. ESP100 OLR Retrofit Capabilities Direct Replacement for: Cutler Hammer Citation Line and Freedom Series GE 300 Line Square D Type S An additional “piggy-back” plate is available to retrofit the following: Allen Bradley Bulletin 509 and Bulletin 709 Westinghouse Series A200
