It uses a magnetic-only MA trip unit for short-circuit protection, the standard configuration for motor-circuit applications that pair it with a separate thermal overload relay. The breaker is fixed-mounted and carries IP40 front-face ingress protection.\u003c\/p\u003e\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eReference\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eLV540552\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eBrand\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eSchneider Electric\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eRange\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eEasyPact CVS\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eDevice short name\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eCVS400N\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003ePoles\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e3P\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eProtected poles\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e3D\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003e[In] Rated current\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e320 A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eTrip unit\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eMA (Magnetic)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003e[Ii] Instantaneous pick-up adjustment\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e6...13x In (adjustable)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003e[Icu] Breaking capacity\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e50 kA at 380\/415 V AC, 42 kA at 440 V AC, 70 kA at 220\/240 V AC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003e[Ics] Rated service breaking capacity\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e50 kA at 380\/415 V AC, 32 kA at 440 V AC, 70 kA at 220\/240 V AC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003e[Uimp] Rated impulse withstand voltage\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e8 kV\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eUtilisation category\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eCategory A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eControl type\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eToggle\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eMounting mode \/ support\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eFixed, backplate or DIN rail\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eConnection (upside\/downside)\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eFront \/ Front, screw terminals\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eConnection pitch\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e45 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eCompatibility code\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eCVS400\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eDimensions (W x D x H)\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e140 x 110 x 255 mm (W x D x H)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eNet weight\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e4.7 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eElectrical shock protection class\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eClass II\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eIP degree of protection\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eIP40\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eAmbient air temperature (operation)\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e-25…+70 °C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch2\u003eCertifications \u0026amp; Standards\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eIEC\u003c\/li\u003e\n\u003cli\u003eGOST\u003c\/li\u003e\n\u003cli\u003eEN 60947-2\u003c\/li\u003e\n\u003cli\u003eIEC 60947-2\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eSelection Notes\u003c\/h2\u003e\u003cp\u003eThe MA trip unit on the CVS400N fires on short-circuit current only - it carries no adjustable thermal overload curve - so this breaker is the motor-circuit configuration: pair it with a separate thermal overload relay or motor circuit protector to cover running overload, and let this breaker clear fault current with its 6...13x In (adjustable) instantaneous pick-up.
