Siemens Contactor, Transformers, 5. 60 Hz LC-Type L-828CCRs, 4-10kW/6.6 A: Required, Equipment

L-828 CCRs LC-Type (4, 7.5, and 10 kW/6.6 A/60 Hz)			Description
Contactor		In the event of an SCR failure, the contactor provides a means to
		break the current driving the primary of the power transformer T1.
		Under normal conditions, the contactor K1 (see Figure 8-1 in the
		Wiring Schematics section) has no making or breaking current across
		it, since the SCR is off when the contactor is opening and closing.
		This is accomplished by the coil-control circuitry and provides
		increased life for the contactor.
Transformers		Transformer T6 provides 120 Vac remote control source voltage at
		TB2 terminal 8 through fuse F3.
		Transformer T3 provides AC voltage to the control PCB. T3 provides
		both 120/60 Vac and 36/18 Vac.
		Refer to Table 2-2 for required equipment that is supplied. Refer to
5. 60 Hz LC-Type L-828 CCRs
(4-10 kW/6.6 A): Required		Table 2-3 for required equipment that is not supplied. Refer to the
		Parts section for ordering information.
