G25B3A250
รายละเอียด
This product is part of the new GoPact Molded Case Circuit Breakers range (MCCB). It is a complete 3 poles circuit breaker made of a 250A breaker frame and of a thermal magnetic trip unit (TMD). GoPact MCCB has a good price-performance ratio for basic applications and delivers a reliable electrical protection for your applications. The breaking capacity (Icu) is 25kA rms at 415VAC 50/60Hz. The operational voltage is 415VAC 50/60Hz. This product embeds a 250A rating (In) thermal-magnetic trip unit (TMD). This TMD trip unit provides an adjustable thermal protection Ir (against overloads) with a setting range from 0.7xIn to 1xIn (175A-250A). And it provides a fixed magnetic (against short-circuits) protection set to 12xIn (3000A). GoPact MCCB comes with a variety of optional accessories simple to choose and to install. Product dimensions are 105mm (Width) x 165mm (Height) x 90mm (Depth). The weight is 1.9 kg. GoPact MCCB 250 is IEC 60947-1 and IEC 60947-2 certified. GoPact MCCB range benefits from Schneider Electric quality assurance.
