Siemens SENTRON 5SV4311-0KL — 2-pole RCCB, 16 A, 30 mA, Type AC
The Siemens SENTRON 5SV4311-0KL is a 2-pole residual current circuit breaker (RCCB) rated 16 A at 50 Hz with a 30 mA trip threshold, Type AC for sinusoidal AC residual currents. The instantaneous design means no intentional delay — it trips within the cycle on a ground fault.
Mounting position is any orientation — no derating for horizontal or inverted installation. The N-left variant means the neutral pole is on the left side of the device, which matters when laying out the distribution board busbar order. IP20 with connected conductors in an installed distribution board; not rated for wet or dusty environments.
Thermal performance and derating
The silicon-free construction matters for potting or conformal coating processes in sensitive environments.
