protection must be provided in accordance with the National Electric Code and any additional local
codes. Branch circuit protection provided by fuses only.
• Suitable for use in a pollution degree 2 micro-environment.
• Motor overload protection provided at 110% of full load current.
• These devices are not provided with motor over temperature sensing, or equivalent.
• In order to maintain the environmental rating integrity of the enclosure, all openings must be closed
by equipment rated 3, 3R, 3S, 4, 4X, 6, or 6P.
• Maximum ambient temperature is 40°C.
