Circuit Breaker Frame/Sensor/Plug - Definitions

[Defenestrator]

Can someone explain to me what the difference between the Frame/sensor/ and plug for a larger circuit breaker? Or provide a link so a whitepaper that does?

For example:

GE WPH-16 with
Frame: 800-2000AF
Sensor: 1600
Plug: 1200
The type/model is Wavepro LVPCB

I think i understand Frame, but im not exactly sure about Plug and Sensor. For context this is for SKM modeling.

Frame is 1600 on a WPH-16. Sensor is the CT rating, plug is the rating plug on the trip unit which would be either a MVT+ or Entilligaurd (Should be a 1600:1200A plug).

are the sensor or plug adjustable in the field without swapping out a some hardware?

No, not on this particular breaker.

I'm not sure if the plug is field replaceable on this particular breaker, but the trip value can be adjusted by adjusting the long time pickup which is a multiplier of the plug (typically 0.5 to 1.1 in steps of 0.1 or 0.05 depending on the trip unit installed. http://apps.geindustrial.com/publibrary/checkout/DET-195?TNR=Data Sheets|DET-195|PDF

The sensor is not field replacable

On other breaker styles, the plug is often replaceable and / or adjustable.

Rating plug is an easy swap that can be done in the field
