The 70 mm width, 140 mm height, and 152 mm depth define the panel footprint.
Rated operational currents for the auxiliary contacts vary by voltage: 10 A at 24 V, 2 A at 48 V, 2 A at 60 V, 1 A at 110 V, 0.9 A at 125 V, 6 A at 230 V, 3 A at 400 V, 2 A at 500 V, 0.1 A at 600 V, and 1 A at 690 V. The arcing time is 10 to 20 ms at AC, with a typical mechanical life of 10,000,000 operations.
The depth is 152 mm.
The auxiliary terminals accept solid conductors: 2x (0.5... 1.5 mm²) and 2x (0.75... 2.5 mm²).
