The Siemens SENTRON 5SJ6215-7 is a 2-pole miniature circuit breaker (MCB) from the 5SJ6 series, rated at 1.6 A with a C-curve tripping characteristic. Rated 400 V AC with a 6 kA breaking capacity per EN 60898 and IEC 60947-2, it safely interrupts fault currents up to that level in a 50 Hz network. The 2-pole design switches both line and neutral simultaneously, which matters for single-phase circuits where disconnecting the neutral is required by local code or for load isolation. Ambient temperature range -20 to +45 °C covers most indoor panel conditions; above 40 °C the thermal trip curve derates per the standard, so don't pack it into a hot cabinet corner without checking the thermal chart.
Wire termination and panel fit
The clamp is sealable. Installation depth is 70 mm, and the breaker occupies 2 width units. Mounting position is any. Touch protection is built in — live terminals are shielded when conductors are connected.
