At 4 A, this is a low-current branch protector, not a main feeder.
Screw terminals accept solid or stranded copper from 0.75 mm² up to 25 mm², with a recommended tightening torque of 2.5 to 3 N·m. IP20 with conductors connected is standard for panel-mounted breakers; no washdown rating. The breaker is sealable for tamper-proof installations.
The 5SL3404-7 is rated for 4.5 kA breaking capacity under both EN 60898 and IEC 60947-2. This covers most residential and light commercial fault levels.
The screw terminals accept solid or stranded copper from 0.75 mm² up to 25 mm². Torque to 2.5–3 N·m.
