Energy storage systems (ESS) require interfaces which are compact and generate as little heat as possible, even when transmitting high currents. Harting has developed the Han S<\/strong> <\/a>series for this application area. The cable side consists of angled housings, with the input side freely rotating around 360 degrees when plugged in. This makes the cables which connect the ESS modules more flexible. Storage modules can also be combined into larger units.

Previously, 200A was the maximum power rating. The power capacity of the new Han S 450 Plus has been increased to 500 A to meet the demand for higher charging and discharging currents for battery storage. The enlarged contacts and housings are designed so that they do not overheat during operation.<\/p>\n\n\n\n

Hartuing has developed larger housings for contacts with three different conductor cross-sections:<\/p>\n\n\n\n

– for 95mm\u00b2 (AWG 3\/0 or 4\/0) up to 350A<\/p>\n\n\n\n

– for 120mm\u00b2 (250 kcmil) up to 400A<\/p>\n\n\n\n

– and for 150mm\u00b2 (300kcmil) up to 450A<\/p>\n\n\n\n


Robustness and ease of use are also benefits of the Han interface. It is guaranteed to withstand up to 500 mating cycles, which no other comparable product can offer. The locking mechanism is intuitive.

The colours red for positive and black for negative, as well as additional colour options of blue and orange, make Han S connections easily identifiable. In addition, the housings feature a double locking system and numerous coding options, including the use of five different mating profiles.<\/p>\n","protected":false},"excerpt":{"rendered":"
