t These thermal unit selections are for controllers protected from
solar radiation and located in an ambient temperature of 40 oC
(104 oF) or less. For overload relays which are not ambient
temperature compensated (NEMA Size 3 and 4), thermal units
larger than normal can be required under conditions of high
ambient temperature and/or solar radiation. Consult your local
Square D field office.
k To select thermal units for Type M part winding devices, first
divide total motor full load current by 2. Use tables above.
u Order Type E thermal units by number from Square D
