Harting: Han Size 4 Delivers High Power Density, Saves up to 40% of Installation Space

Han® Size 4 saves up to 40% of installation space

Han-Eco®, Han® B and Han® HPR are the first connector series featuring Size 4 hoods/housings and inserts. This new size, an intermediary between Han® 3 and Han® 6, offers space savings of up to 40% compared to the next larger size. HARTING thus offers sustainable solutions for environments where installation space is limited to a minimum. There is a particular demand for this in mechanical engineering and automation as well as in energy and transportation applications.

Increase power density

The new size bridges a gap between two standards: the next-largest Han-Eco® 6B, for example, is not suitable for all energy applications, whilst the smaller Han® 3A cannot carry the required 70 A (the maximum is 40 A). Interfaces need to have a small footprint and must simultaneously transmit high currents, as capacities are rising and space is at a premium.

With the new size, users gain space for the rest of the required infrastructure, e.g., for cooling/ventilation. At the same time, the 70 A contacts of the Han-Eco® enable energy savings of up to 50%, which also promotes sustainability. This is primarily due to the low impedance of the silver-plated 70 A power contacts compared to competing products (CEE plugs).

Option for mechanical engineering and robotics

There is also demand for the new size in power distribution and transmission as well as in mechanical engineering. For instance, Size 4 hoods or housings and inserts allow space-saving connections for drives, frequency converters and other equipment to be installed in harsh industrial environments. Special adapters are available for integrating inserts from a range of over 100 different Han-Modular® connectors, including PE conductors.

Siemens: SIMOVAC Non-Arc-Resistant and SIMOVAC-AR Arc-Resistant Motor Controllers

The Siemens SIMOVAC medium-voltage non-arc-resistant and SIMOVAC-AR arc-resistant controllers have a modular design incorporating up to two 12SVC400 (400 A) controllers, housed in a freestanding sheet steel enclosure. Each controller is UL 347 class E2, equipped with three current-limiting fuses, a non-load-break isolating switch, and a fixed-mounted vacuum contactor (plug-in type optional for 12SVC400). The enclosure is designed for front access, allowing the equipment to be located with the rear of the equipment close to a non-combustible wall.
