WEG lists it as “MOTOR PROTECTOR BU MPW40-3-U020”. Key specifications: reference MPW40, maximum rated current Ie 40 A.\u003c\/p\u003e\u003cp\u003eMPW Motor-protective Circuit-breakers offer a compact means of protecting electric circuits and of operating and protecting motors up to 45kW (380V) or 55kW (440V), with a high breaking capacity that permits installation where short-circuit currents are high. Thermal and magnetic releases give complete circuit and motor protection: the thermal release is adjustable for overload protection and carries a differential mechanism with phase-loss sensitivity, while the magnetic release is set at 13xIn for short-circuit protection. Two models are available, ON-OFF by pushbuttons (MPW18) or by handle (MPW40\/80\/100), both with trip indication so the operator can see breaker status, and the handle can be padlocked in the \"OFF\" position for safe maintenance.\u003c\/p\u003e\u003ch3\u003eWEG MPW40-3-U020 Technical Specifications\u003c\/h3\u003e\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eManufacturer\u003c\/th\u003e\n\u003ctd\u003eWEG\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003ePart number\u003c\/th\u003e\n\u003ctd\u003eMPW40-3-U020\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eWEG material number\u003c\/th\u003e\n\u003ctd\u003e12428129\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eWEG designation\u003c\/th\u003e\n\u003ctd\u003eMOTOR PROTECTOR BU MPW40-3-U020\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eProduct type\u003c\/th\u003e\n\u003ctd\u003eMotor Protective Circuit Breaker\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSeries\u003c\/th\u003e\n\u003ctd\u003eMPW\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eReference\u003c\/th\u003e\n\u003ctd\u003eMPW40\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMaximum rated current Ie\u003c\/th\u003e\n\u003ctd\u003e40 A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSetting range for thermal release\u003c\/th\u003e\n\u003ctd\u003e16-20 A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eNumber of poles\u003c\/th\u003e\n\u003ctd\u003e3\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eShort-circuit release\u003c\/th\u003e\n\u003ctd\u003e13 x Iemax\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eRated operational voltage Ue\u003c\/th\u003e\n\u003ctd\u003e690 V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eRated operational frequency\u003c\/th\u003e\n\u003ctd\u003e50\/60 Hz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eRated insulation voltage Ui\u003c\/th\u003e\n\u003ctd\u003e690 V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eRated impulse withstand voltage Uimp\u003c\/th\u003e\n\u003ctd\u003e6 kV\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eUtilization category - IEC60947-2(motor starter protector\/circuit breaker)\u003c\/th\u003e\n\u003ctd\u003eA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eUtilization category - IEC60947-4-1 (Motor Starters)\u003c\/th\u003e\n\u003ctd\u003eAC-3\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eTrip test\u003c\/th\u003e\n\u003ctd\u003eYes\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eOverload protection\u003c\/th\u003e\n\u003ctd\u003eYes\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003ePhase failure sensitivity\u003c\/th\u003e\n\u003ctd\u003eYes\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eTrip indication\u003c\/th\u003e\n\u003ctd\u003eYes\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eTripping class\u003c\/th\u003e\n\u003ctd\u003e10\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMaximum operating frequency (ops.\/h)\u003c\/th\u003e\n\u003ctd\u003e15\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eDegree of protection\u003c\/th\u003e\n\u003ctd\u003eIP20\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eHeight\u003c\/th\u003e\n\u003ctd\u003e97 mm \/ 3.82 in\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eWidth\u003c\/th\u003e\n\u003ctd\u003e45 mm \/ 1.77 in\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eDepth\u003c\/th\u003e\n\u003ctd\u003e98 mm \/ 3.86 in\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eGross weight\u003c\/th\u003e\n\u003ctd\u003e0,36 kg \/ 0.79 lb\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eWEG catalog category\u003c\/th\u003e\n\u003ctd\u003eControls \u0026gt; Motor starters and protection \u0026gt; Motor protective circuit breakers \u0026gt; MPW - Motor protective circuit breaker\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\u003cp\u003eIndustrial Automation Co. offers the WEG MPW40-3-U020 in \u003cstrong\u003enew\u003c\/strong\u003e condition.
