- 3P2D (3 Poles frame with 2 Poles detection) MCCB has an empty pole, it has only two power contacts inside even if the product looks like a 3P MCCB. 3P2D can be used for single phase applications, to control and protect the phase and neutral.
- 3P3D (3 Poles frame with 3 Poles detection) MCCB is a 3P MCCB and thus it protects its 3 terminals not just 2 terminals
- 4P3D (4 Poles frame with 3 Poles detection) MCCB will protect the 3 phases and won't sense any currents on the 4th pole as the 4th pole does not contain a CT and is not connected to Micrologic and thus won't protect the neutral.
- 4P4D (4 Poles frame with 4 Poles detection) MCCB will protect the 3 phases + Neutral.
