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

24. What Is A Short Circuit? Overload Relays
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.

64. True phase loss protection
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. Heaterless Construction Customer Benefit:
Electronic OLR
Heaterless Construction
No heaters to install, stock, or maintain
Customer Benefit:
Heaters require time and labor to install

66. Self - Powered Customer Benefit:
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. Ambient Insensitive Customer Benefit:
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. 99% of heat generated by thermal overload removed Customer Benefit:
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. This can really be significant if user has hundreds of starters!!!
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. Self protected from short circuits
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. ± 2 % repeat accuracy Customer Benefit:
ESP100 OLR
± 2 % repeat accuracy
Customer Benefit:
Under the same conditions, trip time on the overload will be the same within ± 2%

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

73. No two labels are the same
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. Thermal Memory Customer Benefit:
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. Simple Installation Customer Benefit Mount it, wire it, dial in FLA
