With a 400A frame and a breaking capacity of 50kA at 400V AC (75kA at 240V AC), it delivers robust fault current interruption. The thermal\u2011magnetic trip unit provides fixed overload protection, while the compact design (140mm \u00d7 257mm \u00d7 160mm) and front\u2011connection terminals make it ideal for panel builders seeking a space\u2011efficient, high\u2011reliability solution. The NXM series features a thermosetting plastic housing with UL94 V\u20110 flame retardant rating, built\u2011in phase isolation barriers, and compliance with IEC\/EN 60947\u20112 and CCC standards, suitable for global applications.<\/p>\n<div>\n<ul class=\"tight\" dir=\"ltr\" data-tight=\"true\">\n<li>\n<p dir=\"ltr\"><strong>\u9ad8\u3044\u7834\u65ad\u80fd\u529b<\/strong>: Delivers 50kA Icu at 400V AC and 75kA at 240V AC, providing reliable protection under demanding short\u2011circuit conditions.<\/p>\n<\/li>\n<li>\n<p dir=\"ltr\"><strong>\u30b5\u30fc\u30de\u30eb\u30de\u30b0\u30cd\u30c6\u30a3\u30c3\u30af\u30c8\u30ea\u30c3\u30d7\u30e6\u30cb\u30c3\u30c8<\/strong>: \u56fa\u5b9a\u30b5\u30fc\u30de\u30eb\u30de\u30b0\u30cd\u30c6\u30a3\u30c3\u30af\u4fdd\u8b77\u306f\u3001\u7523\u696d\u7528\u914d\u96fb\u306e\u305f\u3081\u306e\u4fe1\u983c\u6027\u306e\u9ad8\u3044\u904e\u8ca0\u8377\u304a\u3088\u3073\u77ed\u7d61\u5fdc\u7b54\u3092\u4fdd\u8a3c\u3057\u307e\u3059\u3002.<\/p>\n<\/li>\n<li>\n<p dir=\"ltr\"><strong>\u30b3\u30f3\u30d1\u30af\u30c8\u3067\u5805\u7262\u306a\u69cb\u9020<\/strong>: Space\u2011saving 140mm width with a thermosetting plastic housing (UL94 V\u20110 flame retardant) for excellent heat dissipation and mechanical strength.<\/p>\n<\/li>\n<li>\n<p dir=\"ltr\"><strong>\u5185\u8535\u76f8\u9593\u7d76\u7e01<\/strong>: \u7d71\u5408\u3055\u308c\u305f\u76f8\u9593\u7d76\u7e01\u30d0\u30ea\u30a2\u306f\u5b89\u5168\u6027\u3092\u5411\u4e0a\u3055\u305b\u3001\u76f8\u9593\u306e\u30a2\u30fc\u30af\u30d5\u30a9\u30eb\u30c8\u306e\u30ea\u30b9\u30af\u3092\u4f4e\u6e1b\u3057\u307e\u3059\u3002.<\/p>\n<\/li>\n<li>\n<p dir=\"ltr\"><strong>\u30d5\u30ed\u30f3\u30c8\u63a5\u7d9a\u7aef\u5b50<\/strong>: Fixed front\u2011wired terminals support cable cross\u2011sections up to 240mm\u00b2, ensuring secure and low\u2011resistance terminations.<\/p>\n<\/li>\n<li>\n<p dir=\"ltr\"><strong>\u5e83\u3044\u52d5\u4f5c\u6e29\u5ea6\u7bc4\u56f2<\/strong>: Reliable performance from \u201135\u00b0C to +70\u00b0C, suitable for harsh industrial environments.<\/p>\n<\/li>\n<li>\n<p dir=\"ltr\"><strong>\u30b0\u30ed\u30fc\u30d0\u30eb\u627f\u8a8d\u304a\u3088\u3073\u6e96\u62e0<\/strong>: Certified to IEC\/EN 60947\u20112, CCC, KEMA, CB, and NOM;
