HARTING Han Q 3/0/Han Q 4/0 3A size range

With the Han Q 3/0 and Han Q 4/0, HARTING is expanding its portfolio in the smallest Han 3A size range. An area measuring 42 mm² is enough room for three power contacts and the protective earth contact (Han Q 3/0) or four power contacts (Han Q 4/0). This is said to make them both the most powerful in the compact industrial connector class.

The connector boasts the following performance data: clearance and creepage distances with the Han 3/0 allow a 400 V rated voltage, which increases to as much as 830 V with the Han Q 4/0. Both have roughly similar current load capacities - this is approx 40 A given an ambient temperature of 40°C and a connection wire gauge of 4 mm². Because connectors with standard Han C contacts can be used with a wire gauge of up to 10 mm², currents of over 80 A are possible, but in these cases the diameter of the cable entry needs to be taken into account.

Both connectors are used in industrial environments. They are suitable for the needs of the semiconductor industry, for example. The Han Q 3/0 with protective earth contact is designed for three-phase earthed networks and is used in three-phase motors. It can fit all housings in the 3A size, ie, all plastic and metal varieties, EMC and also the robust HPR and stainless steel housings. The Han Q 4/0 comes with four power contacts and is used to enable equipment such as ventilators, fans or extraction units to be connected. Because these consumers are very common in the semiconductor industry, the Han Q 4/0 helps reduce costs because two of the consumers can be connected with one connector. The connector is also suitable for DC applications. However, in this case, it can only be used in 3A size plastic housings.
