1. 6HK3 = 3-Phase with terminal block connections only, 6HK4 = 3-Phase with service disconnect.
2. The 20kW and 25kW heater models (6HK46502025 and 6HK46502525) come with circuit breakers standard. Single source power MCA and MOP
requirements are given here only for reference if used with field installed single point power modification (S1-32436041000).
3. MOP = Maximum Overcurrent Protection device; must be HACR type circuit breaker or time delay fuse. The 1st circuit includes blower motor amps.
Refer to the latest edition of the National Electric Code or in Canada the Canadian electrical Code and local codes to determine correct wire sizing.
