Replacement Coil Kit for NEMA Starters
This SIEMENS 75D73070A coil kit replaces worn coils in NEMA-style contactors and starters. It suits maintenance teams and electricians who service motor-control gear rated for NEMA sizes 00 through 2-1/2. The kit restores reliable pull-in and hold-in function on existing equipment.
Verify Contactor Frame and Coil Voltage
Confirm that the contactor carries a NEMA size marking of 0, 00, 1, 2 or 2-1/2 before ordering. The coil is rated for 120/240 V AC at 60 Hz, so the control circuit must supply that voltage and frequency. Mismatched voltage or frame size will prevent correct operation.
Coil Power and Thermal Behaviour
The coil draws 180 VA during energisation, which determines the steady-state heat contribution inside the enclosure. In normal use the coil runs warm but within its design limits, and audible hum is typical for AC coils of this rating. Ensure the enclosure ventilation handles the combined load of all installed coils.

Questions about this item
Does the 75D73070A kit include any mounting hardware or auxiliary contacts, or must those be ordered separately?
The kit is a replacement coil only; mounting hardware and auxiliary contacts are not included and must be sourced separately.
How do I choose the correct coil for a NEMA size 1 versus a NEMA size 2-1/2 contactor?
This single coil kit covers NEMA sizes 00, 0, 1, 2 and 2-1/2, so the same part fits all listed sizes.
What does the 180 VA coil power rating mean for control-circuit transformer sizing?
The coil draws 180 VA at inrush, so the control transformer must supply at least that VA at 120 or 240 V AC, 60 Hz.
