5) 3RV1 MSPs can only be used with 3RT1 contactors
and accessories. 3RV2 MSPs can only be used with
3RT2 contactors and accessories.
6) For 100kA SCCR rated MSPs, change the part number
from 3RV2031 to 3RV2032. (applies to S2 frame only

Description Ordering Information
The 3RV203 / 204 MSPs are UL approved as Self Protected Combination Motor Controllers
which are also called Type E. In this application, all the required functions for a motor
branch are provided in one device: disconnect, short circuit protection, motor control and
overload protection. A type E terminal adaptor is required for all S2 frame 3RV2031 above
45A and all S2 frame 3RV2032 as well as for all S3 frame motor starter protectors.
The 3RV203 / 204 MSPs are also approved for use as follows:
– Manual Motor Controller: Motor starter, motor disconnect, control and overload
protection.
– Group Installation: Motor starter only, motor disconnect, control and overload protection.
– Tap conductor Protection in Group Installation acc. NEC: Motor starter only; motor
disconnect, control and overload protection.
When the 3RV203 / 204 is used with one of the 3 above mentioned approvals, they can be
installed downstream of one circuit breaker or fuse set.

MSPs in control panels in general, in group installations or in accordance to international
IEC standards visit our website: www.usa.siemens.com/controlpaneldesign
