| SUPPLEMENTARY PROTECTION |
| Type D characteristic is designed for high inrush loads. Magnetic trip point - 10 to 20 times In rating. Thermal trip point - 1.13 to 1.45 protector rating. |
| 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 |
