Overview

Accessories for "Self-Protected Combination Motor Controllers (Type E)" according to UL 508/UL 60947‑4‑1

The 3RV20 motor starter protectors with screw terminals are approved according to UL 508/UL 60947‑4‑1 as "Self-Protected Combination Motor Controllers (Type E)". The 3RV1011 motor starter protectors do not have this UL approval.

This requires increased clearances and creepage distances (1 inch and 2 inches respectively) at the input side of the device, which are achieved by mounting a terminal block or a phase barrier. No transverse auxiliary switches may be used when using 3RT2946‑4GA07 terminal blocks for size S3.

Special 3-phase infeed terminals are required for constructing "Type E Starters" with an insulated 3-phase busbar system (see Busbar accessories).

For the setup of "Type E starters" with 8US busbar adapters, Type E terminal blocks or phase barriers (for sizes S00 to S2) must be fitted to the infeed module on the circuit breaker.

The 3RV29 infeed system also enables the assembly of "Type E Starters", see 3RV29 infeed system.

Note:

According to CSA, these terminal blocks and the phase barriers can be omitted when the device is used as a "Self-Protected Combination Motor Controller (Type E)".

Link modules

Feeders can be easily assembled from single devices with the help of the link modules. The following table shows the different combination options for devices with screw or spring-loaded terminals.
