Three-pole, rated 1.6 A continuous current, with a magnetic overcurrent and short-circuit release (no thermal element). Finger-safe IP20 front protection means an operator can touch the front of the installed breaker without shock risk — standard for enclosed panels.
The interrupting rating drops as system voltage rises: 100 kA at 240 V AC, 85 kA at 400 V, 50 kA at 500 V, and 10 kA at 690 V. For a 400 V panel with a transformer rating under 2 MVA, 85 kA is ample — most industrial MCCs spec 65 kA or less. The AC-3 motor-switching rating is 1.6 A at 400 V, same as the continuous rating, so this breaker is sized for a motor full-load current up to 1.6 A — roughly a 0.37 kW motor at 400 V.
Main circuit terminals are screw-type on the front side; auxiliary and control circuit terminals are also screw-type.
