They can often be sized for back-up protection against motor burnout from overload or single-phasing if other overload protective devices fail. * Proper sizing can provide "no damage" Type 2 coordinated protection for NEMA(R) and IEC(R) motor controllers. * Space-saving package for equipment downsizing. * Indicating versions not Vdc rated.
