Siemens 5SU1323-1WM06 SENTRON RCBO — 2-pole, C-curve 6 A, 30 mA, Type AC
It protects a 2-pole (2P) final circuit against both overcurrents (C-curve, rated 6 A) and earth faults (30 mA, Type AC). Rated breaking capacity is 4.5 kA per EN 60898 and 25 kA per IEC 60947-2 — the higher figure applies when the device is used as a standalone circuit breaker under industrial panel rules. Residual-current detection is Type AC (sinusoidal AC fault currents only), at the standard 30 mA threshold for personal protection. The neutral conductor is switched internally, so this RCBO can serve as the main disconnection means for a 2-wire single-phase circuit.
Occupies 4 modular-width units (4 MW) on a DIN rail. Installation depth is 70 mm — verify enclosure depth clearance, especially in shallow consumer units. Touch protection is built in (IP20 with distribution board installed and conductors connected). Operates on 50 Hz AC supply only. Rated operational current is 6 A at AC. Overvoltage category III (distribution-level) and pollution degree 2 (non-condensing, typical for clean indoor panels).
Halogen-free and silicon-free construction. Surge current withstand is 1 kA (8/20 µs waveform). Energy limitation class 3.
