Slim Miniature Circuit Breakers Ex9B40J, 6 kA

• • Slim Miniature Circuit Breakers according to IEC/EN 60898-1

  • Rated short-circuit breaking capacity 6 kA

  • 1 to 4-pole versions

  • Tripping characteristics B, C

  • Rated current up to 40 A

  • Rated operational voltage 230/400 V AC

  • Wide range of accessories

  Ex9B40J slim miniature circuit breakers are suitable for both household and commercial applications. The width of 3/4 module — $13.5~\text{mm}$ per pole instead of $18~\text{mm}$ of standard devices — makes this series the best option for space-demanding installations. The internal structure of the standard Ex9B product family has been preserved in these slim miniature circuit breakers, making the Ex9B40J line fully compatible with standard breaker accessories: shunt trip releases, undervoltage and overvoltage releases, auxiliary contacts, and alarm contacts. Up to three units of auxiliary or alarm contacts, plus up to two units of release units, can be used.
