A4BY1400 is Mersen’s 1400A catalog option in the A4BY Series. The circuit rating is 600V AC \/ 300V DC; published interrupting performance is 200kA AC \/ 100kA DC. Its circuit-protection behavior is defined by 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 Circuit Breakers, Load Centers, Panelboards. Use the official Mersen datasheet to confirm final coordination and dimensions.<\/p>\n","protected":false},"excerpt":{"rendered":"
