At 149 mm deep and 140 mm high, it fits enclosures with those internal dimensions.
Rated operational voltage covers 20 to 690 V AC, handling common line voltages without a separate voltage tap. The screw-type terminals accept 2x (0.5 to 1.5 mm²) solid or stranded, or 2x (0.75 to 2.5 mm²) — enough for motor leads up to about 2.5 mm² without needing a ferrule.
Clearance: 50 mm above and below, 10 mm to the side — so in a row of breakers you need 10 mm between units for cooling. Operating temperature range is -20 to +60 °C, storage/transport -50 to +80 °C — fine for most indoor industrial environments, but if the panel sits in an unheated warehouse, the -20 °C floor is the limit.
