Care of finish
The finished MCC is strong and durable. Always keep the MCC clean. Cleaning with a dry cloth is usually
sufficient. To remove oil and grease stains, use soap and warm water, drying with a soft clean cloth.
Because the color and finish can vary, see the Materials List before touching up with paint. Standard color is
ANSI 61, light gray.
A 12-ounce aerosol ANSI 61 ABB touch-up paint is available under part number 3A31540G03.

part numbers, description, and nameplate data of the device requiring the replacement parts. For replacement
parts, call your nearest ABB office or representative.
