Motor protection circuit breaker PKE series

thermal-magneticoverloadshort-circuit

PKE motor-protective circuit-breakers with electronic wide-range overload protection offer an interesting alternative to the bimetal solution for motor currents up to 65 A. PKE motor-protective circuit-breakers complement the PKZ device family. Wide adjustment ranges Low heat losses Tripping classes greater than CLASS 10 Precise and extremely long-time stable tripping characteristic curves The benefits of the PKE can be implemented in the motor-protective circuit-breaker even more efficiently by the modular design. The PKE has versatile, approved accessories available from the PKZM0 system for safe and rational control panel construction. An interface to SmartWire-DT also incorporates the option for integration into the worls of automation. Reduction of the number of variants with its wide adjustment ranges - Simplifies product selection, reduces the inventory and transport-related costs Short-circuit proof up to 100 kA (400V) up to 32 A 50 kA (400V) to 65 A - Short-circuit calculations and prefusing are not necessary Plug-in trip blocks up to 65A - Enhances service-friendliness (short conversion times, fast commissioning) Accessories from the PKZM0 system - Minimises design engineering requirements, provides flexibility allowing use of standard components Incorporation into the system SmartWire-DT - Increases the levels of system availability by the transfer of process-relevant data
