Siemens announces immediate availability of two new compact quick disconnect switches used with the popular Sinamics G120D distributed drives. This new disconnect switch design mounts directly onto the input power connector of the drive and locks in place to provide a tight, reliable interface, in accordance with ISO 23570-3. Many applications exist in the decentralized distributed power environments, where control cabinets are being replaced with IP65 protected products.
Two versions of the new disconnect switches are now available. A 10-amp rated switch is offered for G120D drives up to 4 kW (5 hp) and features a daisy-chain Power-Y-junction box design to enable power wiring to additional G120D drives. A 25-amp rated version is offered for the heavier-duty 5.5 kW (7.5 hp) and 7.5 kW (10 hp) drive models. This larger unit features a standard Q4/2 pin configuration.
Through the introduction of these new disconnect switches, Siemens can now offer system integrators, OEMs and field maintenance personnel immediate availability to a drive and connector package for a number of applications, according to Robert Soré, product marketing manager, Sinamics general purpose drives at Siemens. “We’ve developed this product line in tandem with our solution partner Harting and we see it expanding our presence in the distributed, decentralized control markets, which include automotive, packaging, metals processing, food and beverage, as well as general conveyorized material handling.”
