Motor protection circuit breakers
Series 330 motor protection circuit breakers provide overload and short circuit protection for motor control applications.
Series 330 motor protection circuit breakers provide overload and short circuit protection for motor control applications. Space-saving models meet UL and CSA standards requirements as manual motor controllers for use as motor disconnects, National Electrical Code requirements for use in multi-motor applications, and IEC standards for circuit breakers and starters providing isolation functionality. Two versions are available with thermal and magnetic trip elements that provide overload and short circuit protection, and magnetic trip element only for short circuit protection. The breakers are suited for use with Series 300 contactors in group motor installations where panel space is limited and device modu-larity is required. They can also be used as manual motor controllers.
