Why replace the contacts as a set?
ABB treats the movable contacts, stationary contacts, and springs as one renewal part. The same instructions say contacts should be replaced when the silver tip is nearly gone and the support is exposed. They also say not to file or dress the contacts because doing so removes contact material.
What does Size 3 and three-pole mean here?
The exact kit number is printed in ABB instructions for NEMA Size 3 CR305 contactors and CR306 starters in three-pole form. It is not the number shown for Size 4, and the same documents separate two- and three-pole coil instructions from four- and five-pole forms.
This page therefore does not publish the kit as universal across all 200-line, 300-line, four-pole, or five-pole devices. Confirm the device family, NEMA size, pole count, and the contact-set number before selection.
