Siemens 5SU1354-1KK13 — SENTRON RCBO, 13 A, 30 mA, Type C
The neutral pole is switched, and the supply can enter from either the top or bottom. This is a current-production part, actively quoted through independent distribution channels.
The 30 mA residual sensitivity provides additional protection against electric shock for socket-outlet circuits and final subcircuits in residential and commercial installations. The 10 kA (EN 60898) / 20 kA (IEC 60947-2) prospective fault current ratings tell you the device can safely interrupt a short-circuit up to those levels — the higher IEC 60947-2 figure is the one that matters for industrial panel coordination. The 1P+N configuration switches both phase and neutral, with the neutral pole making and breaking; this is standard for single-phase final circuits where isolation of both conductors is required.
At 2 modular width units (36 mm wide, 90 mm tall, 77 mm deep including terminals), the 5SU1354-1KK13 snaps onto a standard DIN rail and occupies two adjacent 18 mm slots in a distribution board. The installation depth is 70 mm. Mounting position is unrestricted, and the supply cable can enter from either top or bottom. The IP20 rating is typical for enclosed distribution boards — the touch protection feature is active once conductors are connected.
