Note 1):

Earthing switch motor is identical for HEC 3-6

Note 2):

Disconnector switch motor is identical for HEC 3-6

Note 3):

In principle:Breaker Operating Mechanism “HMB 4.x”, compatible to HEC 3/4

Breaker Operating Mechanism “HMB 4.x”, compatible to HEC 5/6

Breaker Operating Mechanism “AHMA 4”, compatible to “HMB 4.x” w/o additional material

Attention:Project specific configuration (coil voltage, frequency, wiring, etc.)

Note 4):

Arcing chamber configuration is breaker and project specific

HEC 3, HEC 4, HEC 5, HEC 6 are NOT compatible
