Product details

RCBO 20 A, C-curve, 30 mA — panel-builder commissioning notes

The Siemens 5SU1354-1RC20 is a SENTRON RCBO combining overcurrent protection (20 A, C characteristic) with residual current protection (30 mA, Type AC) in a single 2-module-wide unit.

The 30 mA Type AC residual sensitivity catches sinusoidal AC earth faults; it is the baseline choice for most residential and commercial circuits, not for pulsed DC or smooth DC fault types. The 20 A rating on a 2-pole 1P+N design switches the live conductor and switches the neutral, so it fits single-phase circuits where neutral isolation is required.

Integration — DIN-rail fit and panel considerations

The 2-module width (36 mm) occupies the same slot count as a standard 2-pole MCB. IP20 protection applies once the distribution board is installed with conductors connected — the RCBO itself is not sealed against washdown. Humidity tolerance up to 95% non-condensing.

Frequently asked questions

What are the key ratings for 5SU1354-1RC20?

20 A rated current, C tripping characteristic, 30 mA Type AC residual current, 10 kA breaking capacity per EN 60898 and 20 kA per IEC 60947-2, 240 V AC rated voltage, 50 Hz operating frequency, 2-pole 1P+N design in a 2-module width.

Where can I buy 5SU1354-1RC20?

This part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.

Will 5SU1354-1RC20 drop into a panel specified around 5SL6550-7BB?

The 5SL6550-7BB is a 50 A miniature circuit breaker (MCB) without residual current protection, while the 5SU1354-1RC20 is a 20 A RCBO with 30 mA RCD. Both share the same 2-module width (36 mm), 90 mm height, and DIN-rail mounting, so the physical footprint is identical. However, the 5SU1354-1RC20 requires a neutral connection for the residual current electronics and has a lower current rating — it is not a direct functional replacement for a 50 A MCB.

What compliance documentation is available for 5SU1354-1RC20?

The part carries ratings per EN 60898 (10 kA) and IEC 60947-2 (20 kA), which are the relevant product standards for RCBOs. Overvoltage category III and pollution degree 2 are specified. The SENTRON series typically includes CE marking and manufacturer declarations for RoHS and REACH compliance; specific documentation is confirmed at order.
