Eaton MCB, Type D Tripping, DIN Rail Mount - FAZ Series - 278897 FAZ-D20/3
Need a safety solution to keep you and your equipment protected against overcurrent and short-circuit faults? Choose this MCB from Eaton. As a component with type D breaking characteristics, it tolerates very high inductive loads, so it's ideal for use in high-power industrial applications and with heavy-duty equipment such as motors and transformers. Thanks to a maximum breaking capacity of 10kA means you can trust this MCB to handle extreme surges to reliably reduce the risk of equipment failure or fire. A high magnetic trip point minimises the risk of nuisance tripping in load-drawing applications to help avoid downtime.
