3RV20 motor starter protector as "Self-Protected Combination Motor Controller (Type E)"
For approval according to UL 508, a clearance of 1 inch and a creepage distance of 2 inches
are required on the line side for a "Self-Protected Combination Motor Controller".
Therefore, 3RV20 motor starter protectors in size S00/S0 are approved according to UL 508
together with the terminal block (order no. 3RV29 28-1H) or phase barriers (order
no. 3RV2928-1K).
CSA approval does not require extended clearances and creepage distances. The terminal
blocks or phase barriers can, therefore, be omitted for use as a "Self-Protected Combination
Motor Controller" according to the CSA.
3RV20 motor starter protectors are approved as "Self-Protected Combination Motor
Controller" under the following file numbers:
● UL File No. E156943, CCN: NKJH.
● CSA Master Contract 165071, Product Class: 3211 08.
