What is Selective Coordination

Selective Coordination with ATS

A true selective coordination

design must ensure that every Over

Current Protective Device (OCPD)

has higher overcurrent rating and

a longer time-delay than the one

below it so that every fault will be

cleared by the OCPD immediately

ATS Testing

A typical ATS application

a) The ATS has to be able to transfer between two sources

b) The switch must also 1 Be able to withstand a fault and 2 Close-on a fault

Withstand and close rating (WCR) 1 Given in kA for a specific switch voltage upstream

overcurrent protection i A standard ATS is expecting short time protection

from the upstream overcurrent protective devices (OCPD) The ATS is expecting the clear time of the OCPD to be le 3 cycle

ii The Upstream overcurrent device can take many forms molded case circuit breaker insulated case circuit breaker LV power circuit breaker or fusible device

Withstand amp Close Rated ATS

UL Definition The maximum amount of fault current a switch can withstand at a specified voltage for a given amount of time and remain functional

To attain UL Short-Time Rating a transfer switch must undergo and pass

Selective Coordination with ATS

A true selective coordination

design must ensure that every Over

ATS Testing

A typical ATS application

a) The ATS has to be able to transfer between two sources

b) The switch must also 1 Be able to withstand a fault and 2 Close-on a fault

Withstand and close rating (WCR) 1 Given in kA for a specific switch voltage upstream

overcurrent protection i A standard ATS is expecting short time protection

from the upstream overcurrent protective devices (OCPD) The ATS is expecting the clear time of the OCPD to be le 3 cycle

ii The Upstream overcurrent device can take many forms molded case circuit breaker insulated case circuit breaker LV power circuit breaker or fusible device

Withstand amp Close Rated ATS

UL Definition The maximum amount of fault current a switch can withstand at a specified voltage for a given amount of time and remain functional

To attain UL Short-Time Rating a transfer switch must undergo and pass
