Features Invertibility Devices can be rotated to accommodate the desired incoming feed direction Connecting cross bus rated 1200 Amps Siemens exclusive feature QuickConnect QuickConnect reduces bussing connections from many to one- ensuring a single reliable connection instead of multiple connections. Mounting ear Pivot factory installed mounting ears to minimum or maximum position to provide additional stability when mounting equipment onto wall. QuickTorque Eliminates the need for time consuming torque readings, this breakaway nut provides the correct indication of torque of the QuickConnect. When tightened, the outer head twists off at the proper torque for connection, leaving a single nut for future maintenance. Siemens exclusive feature QuickBolt QuickBolt eliminates the requirement to line up mechanical connectionsinstead bolts remain retracted until the openings lineup - allowing the bolts to protrude through automatically. Springs push the bolts through and provide positive pressure to keep bolts in place while wingnuts are attached and tightened. Siemens exclusive feature QuickRoll QuickRoll eliminates the typical metal brackets for mounting modules to the wall. Instead of metal scraping metal QuickRoll allows the module to glide down the mounting rail via a durable nylon wheel inside mounting bracket. 7-3
