Technical characteristics

Type MH

Current carrying capacity

The current carrying capacity is limited by maximum temperature of

materials for inserts and contacts including terminals. The current

capacity curve is valid for continuous, non interrupted current loaded

contacts of connectors when simultaneous power on all contacts is

given, without exceeding the maximum temperature.

Control and test procedures according to DIN IEC 60 512
