The Mersen A4BQ900 combines a 900A rating with the protection characteristics of the A4BQ Series. For coordination, the key ratings are 600V AC / 500V DC and 200kA AC / 100kA DC interrupting performance. The series is engineered around 4-second time delay at 500% rating and very high current limitation. The Class L format uses blade terminals with cartridge/clip mounting. Typical selection contexts include Feeders, Large Motors, Lighting & Heating. Final application limits and dimensional details should be verified against Mersen’s official datasheet.
