"Self-protected combination motor controller (type E)" (up to 32 A)
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.
4.5.10.2 Approval as "circuit breaker" according to UL 489/CSA C 22.2 No. 5-02
3RV27 and 3RV28 as "Circuit Breaker"
These devices are approved as Circuit Breaker according to UL 489 or CSA C22.2 No.5-02
with 100% rated current ("100 %-rated breaker"). As such they can be used as upstream
short-circuit protection devices for "Manual Motor Controller" and "Manual Motor Controller
Suitable for Tap Conductor Protection in Group Installations".
3RV27 and 3RV28 are approved as "Circuit Breaker" under the following file numbers:
● UL File No. E235044, CCN: DIVQ.
● CSA Master Contract 165071, Product Class: 1432 01.
4.5.11 Application environment
Introduction
The following information must be taken into account when planning applications involving
3RV2 motor starter protectors.
Installation altitude
The motor starter protectors are approved for installation altitudes up to 2,000 m. The
reduced air density at altitudes higher than 2,000 meters affects the motor starter protectors'
electrical characteristics. The reduction factors which have to be taken into account when
using motor starter protectors at altitudes higher than 2,000 m can be obtained on request
on the Internet (http://www.siemens.com/automation/service&support
