This latter figure is the ampere interrupting capacity (AIC) of the breaker. Under short-circuit conditions, the calculated or measured maximum prospective short-circuit current may be many times the normal, rated current of the circuit. When electrical contacts open to interrupt a large current, there is a tendency for an arc to form between the opened contacts, which would allow the current to continue. This condition can create conductive ionized gases and molten or vaporized metal, which can cause the further continuation of the arc, or creation of additional short circuits, potentially resulting in the explosion of the circuit breaker and the equipment that it is installed in. Therefore, circuit breakers must incorporate various features to divide and extinguish the arc. The maximum short-circuit current that a breaker can interrupt is determined by testing. Application of a breaker in a circuit with a prospective short-circuit current higher than the breaker's interrupting capacity rating may result in failure of the breaker to safely interrupt a fault. In a worst-case scenario, the breaker may successfully interrupt the fault, only to explode when reset. 63A 3 Pole Industrial Circuit Breaker 20 KAIC .\u003cbr\u003eThe \u003cstrong\u003e\u003ca\u003eChint NM1-125C\/3300\/63A\u003c!--TgQPHd|||[]--\u003e\u003c\/a\u003e\u003c!--TgQPHd|||[[[\"1668943730363944298\",null,\"17341341303307687319\",\"17341341303307687319\",null,null,null,null,\"hg\",null,null,null,null,null,null,null,null,null,null,29,null,null,null,null,null,null,null,null,\"Chint NM1-125C\/3300 Moulded Case Circuit Breaker (Type C-3 Pole MCCB) NM1-125C\/3300 63A\",null,null,\"4064910939205842900\",null,null,null,null,\"Chint 63A 3 Pole Industrial Circuit Breaker 3 Phase 125AF 20 KAIC 400VAC Circuit Breakers  NM1-125C\/3300\/63A\",[null,\"Chint 63A 3 Pole Industrial Circuit Breaker 3 Phase 125AF 20 KAIC 400VAC Circuit Breakers  NM1-125C\/3300\/63A\",null,6],null,null,null,0,\"EswBCowBQUppVDR0THFWSVlzM1FEVmRmZ255MXBFTi0zSmZwaTBlQk15LWp5b0ZHVHN1MlFXdlVSNkRsb01hVnRSbjFtamkydi16Z1ViR2pibndkNjNQWUZvX3U3czBwQlRKY0UxOWtTcXh2QVM0U2FRUzhKc1lpZ3hxLXZzOS1lMXVBcmRRVmZvd3NfMEtzTEoSF29SLWlhcmU2TGVxRjJyb1AyWkR1aUFvGiJBRHNyOWZRQ3pnTmxNV1c5V0U0UGMwMmk3TmhMYnVOU053\",null,null,0],null,0,1,\"EtYDCswDIskDaHR0cHM6Ly93d3cuZ29vZ2xlLmNvbS9zZWFyY2g_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\",null,null,null,null,null,null,null,null,null,null,null,null,null,null,null,[null,1,0,1,null,null,null,null,null,null,null,null,[251717,null,1],null,null,[{\"395\":[null,null,null,[null,[2510000000,\"PHP\"],null,null,null,\"Chint NM1-125C\/3300 Moulded Case Circuit Breaker (Type C-3 Pole MCCB) NM1-125C\/3300 63A\",null,[\"1668943730363944298\",1,154]]],\"470\":[[\"17341341303307687319\",\"17341341303307687319\",null,null,null,null,\"313514149\",null,\"4064910939205842900\",null,null,null,null,null,[\"17341341303307687319\",\"11893246655152967294\",null,\"1788708782265442\",\"1788708782265442\",\"1788965139597459\"],null,null,null,null,null,null,null,null,null,null,null,null,null,null,null,null,null,[[\"17341341303307687319\",\"11893246655152967294\",null,\"1788708782265442\",\"1788708782265442\",\"1788965139597459\"],null,\"17341341303307687319\",\"313514149\",null,null,1,[[1789009828934363,34554225,1093157038],null,0],null,\"shopify_PH_9143710646489_46480520085721\",\"en\",[\"313514149\",0,\"https:\/\/khmtools.com.ph\",\"KHM Megatools Corp.\"],null,null,null,1,null,null,null,null,null,1,\"14456830270460390008\",[996400,996296,986984,969380,714844],[null,\"14456830270460390008\",\"11541608857067499977\"]]]]}],null,null,null,null,[null,null,\"\/search?ibp\\u003doshop\\u0026prds\\u003dpvt:hg,pvo:29,imageDocid:1668943730363944298,headlineOfferDocid:17341341303307687319,productDocid:17341341303307687319\\u0026q\\u003dproduct\"]],0],\"\"]--\u003e\u003c!--TgQPHd|||[]--\u003e\u003c!--TgQPHd|||[]--\u003e\u003c!--TgQPHd|||[]--\u003e\u003c\/strong\u003e is a \u003cmark\u003e\u003c!--qkimaf zq4b4b_x\/HugV6--\u003e\u003c!--cqw1tb zq4b4b_x\/HugV6--\u003e3-pole, 3-phase \u003cstrong\u003eMoulded Case Circuit Breaker (MCCB)\u003c!--TgQPHd|||[]--\u003e\u003c\/strong\u003e rated for \u003cstrong\u003e63A current capacity\u003c!--TgQPHd|||[]--\u003e\u003c\/strong\u003e, a \u003cstrong\u003e125AF frame size\u003c!--TgQPHd|||[]--\u003e\u003c\/strong\u003e, and a \u003cstrong\u003e20 kAIC breaking capacity\u003c!--TgQPHd|||[]--\u003e\u003c\/strong\u003e at 380–415VAC\u003c!--TgQPHd|||[[[null,null,null,null,null,null,null,null,null,null,null,null,[247864,null,0]]]]--\u003e\u003c\/mark\u003e.
