Product details

What this RCBO does on the rail

It carries a 16 A rated current with C-curve tripping characteristic for moderate inrush loads like motor starters or lighting banks, and a 30 mA Type AC residual current trip for sinusoidal fault currents. Breaking capacity is 4.5 kA per EN 60898 for residential infrastructure, with an IEC 60947-2 rating of 15 kA for industrial panel coordination.

Temperature range and environmental fit

Snaps onto standard DIN rail; supply can land on either top or bottom terminals — no forced orientation. IP20 rating applies once conductors are connected inside a distribution board. The 4 MW footprint means it occupies four 18 mm slots; plan derating when packing multiple RCBOs in a sealed enclosure.

Frequently asked questions

What are the key ratings for 5SU1323-1BB16?

16 A rated current, 30 mA residual current, C-curve tripping characteristic, 4.5 kA breaking capacity per EN 60898, and 15 kA per IEC 60947-2.

Where can I buy the 5SU1323-1BB16 and get current pricing?

Sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.

What is the operating temperature range of this RCBO?

Rated from -40 °C minimum to 75 °C maximum ambient.

Does the 5SU1323-1BB16 fit the same panel as the 5SL6220-7?

No — the 5SL6220-7 is a 2-pole MCB without residual current protection, while this is a 2-pole RCBO with a 30 mA RCD. They share the same DIN-rail mounting and 70 mm depth, but the RCBO occupies 4 MW versus 2 MW for the MCB, so a panel wired for the MCB will lack the space and the neutral/earth connections needed for the RCBO.
