All ampacities noted above include air handler motor amps
Circuit 1: Single-phase for Air Handlers / Circuit 2: Three-phase
for HKR3 Heater Kits
¹ Minimum Circuit Ampacity (Heater Amps + Motor Amps) X 1.25
² Maximum Overcurrent Protection = 2.25 X Motor Amps +
Heater Amps
* Revision level that may or may not be designated
C = Circuit Breaker Option
--- indicates Not Required
HKA meets the new UL1995 requirements for 15 and 20KW heaters
• Only applicable when HKA kits are included in table
• MBVC and MBR models
