Rated 400 V AC (max 440 V in multi-phase operation), this 4-pole breaker handles three-phase plus neutral on a single module. If your installation requires higher fault current (10 kA or 25 kA), this part is not the right choice; look to the 5SL6 series variants with higher interrupting ratings. Wire range accepts 0.75 to 25 mm² solid or stranded, with a tightening torque of 2.5 to 3 N·m on the screw terminals.
Integration notes
The housing is sealable (tamper-evident seal available) and touch-protected per the product feature. No neutral conductor switching on this 4P unit; the neutral is switched with the poles.
