It is suitable for electricians, panel builders, contractors and maintenance teams who need protection that can be set to match the actual load on industrial and larger commercial distribution boards. Available in two adjustable current bands from 240A to 400A, in both 3 Pole and 4 Pole configurations.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication:\u003c\/strong\u003e Suitable for main distribution boards, motor control centres and heavy machinery feeder circuits\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eKey specification:\u003c\/strong\u003e Adjustable thermal 0.8-1 x In, fixed magnetic trip above 10 x In, 50kA Icu \/ 35kA Ics @ 400V, 690V rated operating voltage\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCurrent range:\u003c\/strong\u003e 240-300A or 320-400A\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePole configuration:\u003c\/strong\u003e Available in 3 Pole or 4 Pole\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBuild quality:\u003c\/strong\u003e SABS approved to IEC 60947-2 \/ SANS 556-1, 400H frame\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color:#2C3892;\"\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eAdjustable thermal trip lets you set the protection point within each band, reducing the number of fixed ratings you need to stock\u003c\/li\u003e\n  \u003cli\u003eFixed magnetic trip above 10 x In for fast short-circuit clearance\u003c\/li\u003e\n  \u003cli\u003eMoulded case construction for durability in panel and enclosure installations\u003c\/li\u003e\n  \u003cli\u003eRated for continuous operation at 690VAC, 50\/60Hz\u003c\/li\u003e\n  \u003cli\u003eCompatible with matching shunt release, auxiliary contacts, alarm contacts, under-voltage release and vari-depth handle accessories for the 400H frame range\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color:#2C3892;\"\u003eTypical Applications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eIndustrial and commercial main distribution boards\u003c\/li\u003e\n  \u003cli\u003eMotor control centres\u003c\/li\u003e\n  \u003cli\u003eHeavy machinery feeder protection\u003c\/li\u003e\n  \u003cli\u003eGenerator and genset protection circuits\u003c\/li\u003e\n  \u003cli\u003eSub-main protection on larger installations where load current may vary or grow\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color:#2C3892;\"\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eBrand\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eOnesto\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eRange\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eKCM5\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eProduct type\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eAdjustable Thermal Moulded Case Circuit Breaker (MCCB), mixed load\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eFrame size\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e257 x 140 x 103mm\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eCurrent rating (adjustable band)\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e240-300A \/ 320-400A (select variant)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eTrip unit\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eAdjustable thermal 0.8-1 x In, fixed magnetic \u0026gt;10 x In\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003ePoles\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e3 Pole or 4 Pole (select variant)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eBreaking capacity\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e50kA Icu \/ 35kA Ics @ 400V\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eRated operating voltage\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e690VAC\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eStandards\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eIEC 60947-2, SANS 556-1 (SABS approved)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch3 style=\"color:#2C3892;\"\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1 x Onesto KCM5 400H Frame Adjustable Thermal MCCB (as per selected current band and pole configuration)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003ePlease note:\u003c\/strong\u003e Enclosures, shunt release, auxiliary contacts, alarm contacts, under-voltage release, vari-depth handles and extension connectors are not included and are available separately.\u003c\/p\u003e\n\n\u003ch3 style=\"color:#2C3892;\"\u003eInstallation \u0026amp;
