ELECTRICAL CONNECTION STYLES

Several industry-standard arrangements are used for:
-		Motor lead-wire connection to the INTERNAL ends of a terminal's pins
-		Power supply wire connection to the EXTERNAL ends of the terminal's pins

	CLUSTER-BLOCK	QUICK-CONNECT	STRAP & BLOCK
INTERNAL
EXTERNAL

Each of these connection styles requires a different feature on the end of the hermetic terminal's pins

CLUSTER-BLOCK

This style does not require any additional component on the terminal pins. The Vitrus terminal appears exactly as shown in the drawings on the product family pages

QUICK-CONNECT

The "male" component of this connection arrangement is welded to the ends of the terminal pins, as shown below. The finish of this component can be selected to provide a "color code" to identify if the terminal pins are solid stainless steel or copper-cored stainless steel. (The "female" part of this connection arrangement is supplied by the motor and compressor manufacturers, crimped on the ends of the power supply and/or motor wires.)

STRAP & BLOCK

If heavy gauge power supply wiring is involved in the compressor installation, this connection style is used. A "strap tab" is welded to the external ends of the terminal pins, as shown below. (The mating part, a plastic connector block with threaded inserts and screws, is purchased separately.)
