At 2500A, A4BY2500 is one of the rated options available in Mersen’s A4BY Series. Electrical limits are 600V AC \/ 300V DC, with 200kA AC \/ 100kA DC interrupting capability. The design focuses on 4-second minimum time delay at 500% rating for service and feeder protection. The Class L format uses blade terminals with cartridge\/clip mounting. Typical selection contexts include Switchboards, Mains, Feeders. Check the official Mersen datasheet before final equipment coordination.<\/p>\n","protected":false},"excerpt":{"rendered":"
A4BY2500 extends the Mersen A4BY Series lineup with a 2500A rating. Its key ratings are 600V AC \/ 300V DC and 200kA AC \/ 100kA DC interrupting capability. Its selection value is strongest where the circuit needs 4-second minimum time delay at 500% rating for service and feeder protection.<\/p>\n","protected":false},"featured_media":87122,"template":"","product_category":[121],"product_tag":[10865,10881,1894,10581,300],"product_brand":[10577],"product_voltage":[812],"fuse_speed":[20960,14],"fuse_class":[1443],"package_size":[1450],"mounting_type":[30,20597],"product_application":[5392,2040,21081,19779,1829,5363],"product_standard":[1471,1474],"product_current_type":[77],"product_series":[10864],"product_approval":[256,488],"product_availability":[501,21067],"class_list":["post-229987","product","type-product","status-publish","has-post-thumbnail","hentry","product_category-class-l-fuses","product_tag-a4by-series","product_tag-a4by2500","product_tag-class-l","product_tag-mersen","product_tag-time-delay","product_brand-mersen","product_voltage-600v","fuse_speed-retardo-de-tiempo","fuse_speed-time-delay","fuse_class-class-l","package_size-class-l","mounting_type-cartridge-clip","mounting_type-de-cartucho-clip","product_application-circuit-breaker-protection","product_application-feeder-circuits","product_application-paneles-de-distribucion","product_application-proteccion-de-interruptor-automatico","product_application-residential-load-centers","product_application-switchboard-mains","product_standard-csa-c22-2-no-248-10","product_standard-ul-248-10","product_current_type-ac-dc","product_series-a4by-series","product_approval-csa","product_approval-ul-listed","product_availability-contact-for-availability","product_availability-contacte-para-disponibilidad"],"_links":{"self":[{"href":"https:\/\/fusestock.com\/es\/wp-json\/wp\/v2\/product\/229987","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/fusestock.com\/es\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/fusestock.com\/es\/wp-json\/wp\/v2\/types\/product"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/fusestock.com\/es\/wp-json\/wp\/v2\/media\/87122"}],"wp:attachment":[{"href":"https:\/\/fusestock.com\/es\/wp-json\/wp\/v2\/media?parent=229987"}],"wp:term":[{"taxonomy":"product_category","embeddable":true,"href":"https:\/\/fusestock.com\/es\/wp-json\/wp\/v2\/product_category?post=229987"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/fusestock.com\/es\/wp-json\/wp\/v2\/product_tag?post=229987"},{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/fusestock.com\/es\/wp-json\/wp\/v2\/product_brand?post=229987"},{"taxonomy":"product_voltage","embeddable":true,"href":"https:\/\/fusestock.com\/es\/wp-json\/wp\/v2\/product_voltage?post=229987"},{"taxonomy":"fuse_speed","embeddable":true,"href":"https:\/\/fusestock.com\/es\/wp-json\/wp\/v2\/fuse_speed?post=229987"},{"taxonomy":"fuse_class","embeddable":true,"href":"https:\/\/fusestock.com\/es\/wp-json\/wp\/v2\/fuse_class?post=229987"},{"taxonomy":"package_size","embeddable":true,"href":"https:\/\/fusestock.com\/es\/wp-json\/wp\/v2\/package_size?post=229987"},{"taxonomy":"mounting_type","embeddable":true,"href":"https:\/\/fusestock.com\/es\/wp-json\/wp\/v2\/mounting_type?post=229987"},{"taxonomy":"product_application","embeddable":true,"href":"https:\/\/fusestock.com\/es\/wp-json\/wp\/v2\/product_application?post=229987"},{"taxonomy":"product_standard","embeddable":true,"href":"https:\/\/fusestock.com\/es\/wp-json\/wp\/v2\/product_standard?post=229987"},{"taxonomy":"product_current_type","embeddable":true,"href":"https:\/\/fusestock.com\/es\/wp-json\/wp\/v2\/product_current_type?post=229987"},{"taxonomy":"product_series","embeddable":true,"href":"https:\/\/fusestock.com\/es\/wp-json\/wp\/v2\/product_series?post=229987"},{"taxonomy":"product_approval","embeddable":true,"href":"https:\/\/fusestock.com\/es\/wp-json\/wp\/v2\/product_approval?post=229987"},{"taxonomy":"product_availability","embeddable":true,"href":"https:\/\/fusestock.com\/es\/wp-json\/wp\/v2\/product_availability?post=229987"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
