Overload Relays
• What is the Difference:
Between A Short Circuit & An Overload ?
Siemens Energy & Automation
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.
Siemens Energy & Automation
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.
Siemens Energy & Automation
Overload Relays
• What Are The Differences Between …
• A Fuse Or A Circuit Breaker And An Overload Relay?
Siemens Energy & Automation
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

Siemens Energy & Automation
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
Siemens Energy & Automation
Electronic OLR
• Heaterless Construction– No heaters to install, stock, or maintain
• Customer Benefit: – Heaters require time and labor to install
Siemens Energy & Automation
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
Siemens Energy & Automation
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.
Siemens Energy & Automation
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.
Siemens Energy & Automation
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!!!
Siemens Energy & Automation
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
Siemens Energy & Automation
ESP100 OLR
• ± 2 % repeat accuracy
• Customer Benefit: – Under the same conditions, trip time on the
overload will be the same within ± 2%
Siemens Energy & Automation
ESP100 OLR
• Circuit boards have conformal coating on them.
• Customer Benefit: – Rugged design that will hold up in humid,
corrosive environments
Siemens Energy & Automation
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!
Siemens Energy & Automation
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
Siemens Energy & Automation
ESP100 OLR
• Simple Installation – Mount it, wire it, dial in FLA
• Customer Benefit – Fewer connections, saves installation time
Siemens Energy & Automation
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
