The W171DIP-6 part of Schneider is a floating, miniature circuit breaker (MCB) with a snap-on mounting that is suitable for distribution systems with low fault levels up to 6A. It provides overload and short-circuit protection through an adjustable, thermal-magnetic trip mechanism to protect against overloads and short-circuits. The W171DIP-6 has a range of features, including a reliability enhancement feature which eliminates the need to change the MCB every 10 years due to tripping, as well as a true power ON/OFF indication. Furthermore, it also features a selectable breaking capacity of 300mA, 500mA, or 700mA and can be used solely or in combination with other wiring systems.
