■ Overview
Solder pin connections
Solder pin terminals are available for the main contacts and
transverse auxiliary switches of size S00 motor starter
protectors.
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.
3RV19 18-5A
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)".
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.
• 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.

According to CSA, these terminal blocks can be omitted when
the device is used as a "Self-Protected Combination Motor
Controller" (Type E).
Three-phase feeder terminals are required for constructing
"Type E Starters" with an insulated busbar system (see "Busbar
Accessories").
