3RV Motor Starter Protectors/Circuit Breakers up to 100 A Accessories Mounting accessories Overview Solder pin connections Solder pin terminals are available for the main contacts and transverse auxiliary switches of size S00 motor starter protectors. Size S0: The 3RV19 28-1H terminal block is simply screwed onto the basic unit. Size S2: The basic unit is already compliant with the new clea- rance and creepage distance requirements. Size S3: The standard box terminal must be replaced by the 3RT19 46-4GA07 terminal block. The prepared terminal parts are clamped to the upper and lower screw terminals of the motor starter protectors which allows them to be soldered into printed circuit boards.

Terminals for "Self-Protected Combination Motor Control- lers (Type E)" acc. to UL 508 The 3RV10 motor starter protectors size S0 and higher are ap- proved according to UL 508 as "Self-Protected Combination Mo- tor Controllers (Type E)". Three-phase feeder terminals are required for constructing "Type E Starters" with an insulated busbar system (see "Busbar Accessories") .

This requires increased clearance and creepage distances (1 inch and 2 inches respectively) at the input side of the device, which are achieved by mounting terminal blocks.
