23 January 2021

Issue:
Power Loss
Watts Loss
Contact Resistance
Voltage Drop

Product Line:
Circuit Breakers

Environment:
Applies to Multi-9, C60 Circuit Breakers (UL489 and UL1077)

Resolution:
The attached document gives the Power Loss (Watts Loss) and Voltage Drop per pole, at rated current of the breaker (nominal current). For example, a 1A breaker would be expected to have a Watts Loss per pole of 2.3 W, at rated current of 1A. This information can be used to calculate voltage drop when used at other than nominal current.
