What this MCB covers
The Siemens 5SL6350-6CC is a 3-pole miniature circuit breaker from the SENTRON 5SL6 series, rated 50 A at 400 V AC with a B tripping characteristic.
Tightening torque is 2.5 to 3 N·m; use a torque screwdriver to avoid terminal damage or loose connections. Mounting position is any, so vertical or horizontal rail orientation is fine.
Halogen-free and silicon-free construction, rated for ambient temperatures from -25 to +45 °C during operation (storage -40 to +75 °C). Sealable for tamper-proof installations. Touch protection is built in — no live parts exposed when wired correctly.
