2.4.6 Terminals for "Combination Motor Controller Type E" in acc. with UL 508
Since July 16, 2001, 1 inch air clearance and 2 inch creepage distance is
required for "Combination Motor Controller Type E" on the input side in acc.
with UL 508. Use terminal blocks 3RV1928-1H and 3RT1946-4GA07 for the
3RV10 circuit breakers in frame sizes S0 and S3. The 3RV10 circuit breaker
in frame size S2 complies with the required air clearance and creepage dis-
tance without a terminal block. Terminal blocks are not required for use in
acc. with CSA. These terminal blocks cannot be used in the S0 frame size at
the same time as the 3RV19.5 3-phase busbars or in the S3 frame size at
the same time as a transverse auxiliary switch.
