121733 PKE12/XTU-12 Eaton 3 → 12 A Motor Protection Circuit Breaker, 690 V ac

Eaton Motor Protection Circuit Breaker - PKE Series_x000D_ Eaton's PKE series of motor protection circuit breakers offer a wide adjustment range in a simplified product selection, making choosing the correct product easier, reducing inventory and transport related costs. The PKE motor protection circuit breakers complement the PKZ device family._x000D_ This motor protection range of circuit breakers have precise and extremely long time stable tripping characteristic curves with tripping classes of greater than class 10. The PKE range are short-circuit proof rated to 100 kA (400V) up to 32 A and 50 kA (400V) to 65 A, this means that short-circuit calculations and prefusing are no longer necessary. With electronic wide range overload protection these circuit breakers offer an alternative to the bimetal solution for motor current of up to 65 A and provide protection from electrical faults such as an overload of high voltages, short circuits or relay shutdowns._x000D_ The PKE series has an efficient modular design that allows use of standard components and minimises design engineering requirements. Accessories are available from the PKZM0 system and are ideally suited to a safe and logical control panel assembly. Accessories including auxiliary contacts, trip indicating auxiliary contacts, voltage release and shunt trips can be installed without tools and greatly reduce installation time._x000D_ The PKE system can easily be incorporated into the SmartWire-DT system either individually or as a motor starter combination. Using this system the measurement and status data of the PKE can be sent directly to the control for processing or to a HMI for visualisation of the output circuit data._x000D_ Features & Benefits_x000D_ • Manually-actuated motor protective circuit breaker_x000D_ • Rotating handle with clear indication of switch position, ON, OFF and TRIPPED_x000D_ • Wide adjustment ranges_x000D_ • Plug in trip blocks up 65 A_x000D_ • Forms part of the xStart family of control gear products_x000D_ • Compatible with the SmartWire-DT system to increases the levels of system availability by the transfer of process-relevant data_x000D_ • Shares accessories with the PKZM0 system_x000D_ • Standard trip block 1 - 4 A for PKE12 & PKE 32: 774-0174_x000D_ • Standard trip block 3 - 12 A for PKE12 & PKE 32: 774-0162_x000D_ • Standard trip block 8 – 32 A for PKE32: 774-0171_x000D_ • Advanced trip block 0.3 – 1.2 A for PKE12 with connection to SmartWire-DT: 774-0178_x000D_ • Advanced trip block 8 – 32 A for PKE32 with connection to SmartWire-DT: 774-0180_x000D_ What is a motor protection circuit breaker?_x000D_ Electric motors need protection from phase unbalances, current overload and losses, circuit breakers or MPCBs offer motor protection and prevent short circuits by disconnecting the current. Thermal protection guards against overload, magnetic protection protects against short circuits and faults and phase protection guards against phase loss or imbalance. MCPs or motor circuit protectors only protect against short circuits and generally need an overload relay installing, whereas an MPCB doesn't usually need an overload relay offering magnetic protection and preventing thermal overload. MCPBs can also be integrated into a unit with other devices._x000D_ Eaton Motor Protection Circuit Breaker, 12 A, 690 V AC - PKE Series - PKE12/XTU-12_x000D_ Protect electric motors from unbalanced phases or current overload with this circuit breaker from Eaton. Its screw-in terminal makes it easy to wire, while its manual rotary switch is simple to operate. Use it for pumps, fans and crushers. The motor protection circuit breaker provides precise and extremely stable tripping characteristic curves for improved motor safety. Its modular design is highly compatible with other components for efficient control panel assembly. This unit includes magnetic protection against short circuits and doesn't need to be used in conjunction with a relay._x000D_ • Plug-in technology for fast and simple mounting_x000D_ • Wide range of current settings for optimised efficiency_x000D_ • Electronic wide-range overload protection up to 32 A for greater versatility of use_x000D_ • Two independent separate contact systems in the motor starter for additional safety_x000D_ When should I use a motor protection circuit breaker rather than a motor circuit protector?_x000D_ Motor circuit protectors only protect against short circuits and need a relay to protect against overloads. Motor protection circuit breakers don't need a relay to prevent thermal overloads, making them a more efficient and simple-to-use option for integrating into a system._x000D_ Note_x000D_ Eaton formerly known as Moeller
