2 8 Product Family Overview May 07 Contents Description Page Selection Product Selection Accessories Technical Data and Specifications Dimensions Reference Data Pushbutton Rotary Product Description Eaton s new XT family of Manual Motor Protectors (MMPs) features a pushbutton or rotary ON/OFF manual disconnect, Class adjustable bimetallic overload relay and fixed magnetic short circuit trip capability in one compact unit. Two frame sizes are available: Frame B ( mm) for motors with ratings up to 2A and Frame D ( mm) covers motor ratings up to 6A. Application Description The XTPB and MMPs can be used in the following applications. Motor Protective Circuit Breaker In many countries outside of the United States and Canada, especially Europe, the MMPs are tested and classified as thermal magnetic circuit breakers for use in motor branch circuits. This can be an important consideration for all companies who export their equipment and machines internationally. Both the XTPB and conform to IEC/EN 607 and have the CE Mark. The XTPB and MMPs are UL Listed under UL 8 as. They provide an economical solution for applications requiring simple manual starting and stopping of motors. When used as an MMP, they are typically installed in an enclosure. Many enclosures are offered as accessories for the MMPs. Separate short-circuit protective devices, such as circuit breakers or fuses, are wired ahead of the MMPs. The short-circuit protective device should be sized per the NEC code and should not exceed 00% of the maximum dial setting of the MMP. Group Motor Installations A Group Motor Installation can be defined as more than one motor circuit protected by a single set of fuses or circuit breaker on a motor branch circuit. This eliminates the need for individual fuses or circuit breakers for each motor circuit. Substantial component cost savings, panel space savings and reduced wiring installation time can be achieved in Group Motor Installations. The MMPs are tested and listed for group installation. If remote operation is required, a magnetic contactor can be wired in series with the MMP. See Figure 8. Article 0. of the National Electric Code contains the rules and requirements for Group Motor Installations. Refer to Application Note AP000E for NEC requirement for group motor installation.

Protection in Different Controller Types A UL 8 Type E Self-protected Manual Combination Starter/Motor Controller consists of a single device having integral short circuit protection, a main set of contacts, motor overload protection, and may also include a UL listed Line Side Adapter (see Figure ). This type of controller is a legitimate short circuit protective device and disconnect means for the downstream motor. It does require an upstream feeder short circuit protective device, but does not require a dedicated branch circuit protection or a disconnect means. A UL 8 Type E rating means that the unit clears a fault and does not experience any welding of the power poles. A UL 8 Type E self-protected manual combination starter will remain fully functional should a short circuit within its ratings occur. A UL 8 Type F Self-protected Combination Motor Controller consists of a UL 8 Listed Type E Self-protected Manual Combination Starter/Motor Controller, a UL Listed Contactor, and possibly a UL Listed. While the Type E self-protected manual motor controller of this combination motor controller device is a legitimate short circuit protective device and disconnect means for the downstream motor, the contactor is not self-protected. E.g. XTCE007 XTCE06. In addition, as a complete assembly or modular components, the device should have Type 2 Coordination certification. Type 2 Coordination means the Starter or the Controller must exhibit little or no damage following a major short circuit fault and should be able to be returned to proper service without replacing any parts. Component in a Combination Motor Controller The XTPB and MMPs can also be wired in series with a magnetic contactor to complete the assembly of a remotely operated, combination motor controller.
