Product details

What this MCB brings to the panel

The Siemens SENTRON 5SL3406-7MB is a 4-pole miniature circuit breaker with a C tripping curve, rated 6 A at 400 V AC. Its 4.5 kA breaking capacity per EN 60898 and IEC 60947-2 means it clears faults up to that level without upstream damage in residential and infrastructure panels.

Screw terminals accept solid or stranded conductors from 0.75 to 25 mm². Tightening torque is 2.5 to 3 N·m — enough for a secure connection without stripping the terminal on Al or Cu conductors. Touch protection is built in; IP20 with connected conductors.

Ambient temperature range is -25 to +45 °C during operation; storage from -40 to +75 °C. Overvoltage category 3, energy limiting class 3.
