Description
MS132 Manual Motor Starters with screw terminals are approved as Self-Protected Combination Motor Controllers (Type E) acc. to UL60947-4-1. For this air clearance and creepage distances on the line side of MS132 must be increased, which can be achieved by either mounting S1-M3-25 or S1-M3-35 3- phase feeder blocks or by mounting TS1 terminal spacers. TS1 terminal spacers cannot be used for group installations that involve PS1 compact busbars.
