- Clear and visible conductor connection in front of the rear busbar facilitates controls
- The conductor is easily inserted into the terminal thanks to the large and easily accessible wiring space
- Double terminal chambers permit accommodation of two wires of different cross-sections
- Quick and easy manual removal of miniature circuit breakers from the busbar assembly, for example if connections need to be changed
- Time saving replacement of parts as busbars no longer need to be freed from adjacent devices
- For the quick and easy mounting of auxiliary switches and fault signal contacts
- Captive metal brackets on the additional components ensure the quick and easy mounting of devices on the miniature circuit breakers without the need for tools
- Class D-trip
- Type D characteristic is designed for high inrush loads
- 10 to 20 times magnetic trip point rating
- 1.13 to 1.45 thermal trip point protector rating
