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
