Product details

Rated 16 A with a 30 mA residual trip, Type AC, C-curve characteristic. This is the current-production variant, still actively manufactured.

16 A rated current at 230/240 V AC covers most single-phase final circuits — lighting, general-purpose sockets, small appliances. The 1P+N configuration switches the line conductor and disconnects the neutral, which is required in many regional wiring rules for final circuits.

Where it goes in the panel

Depth is 77 mm, installation depth 70 mm — fits standard distribution boards and sub-distribution enclosures. Supply can enter from top or bottom, which simplifies busbar routing in dense panels. IP20 rated once installed with conductors connected, so it belongs inside a distribution board, not in a wet or dusty location.

Frequently asked questions

What is the breaking capacity of 5SU9356-1CR16?

6 kA per EN 60898 and 10 kA per IEC 60947-2 — the higher figure applies when the installation is designed to the industrial standard.

What does Type AC residual current mean?

Type AC detects sinusoidal AC fault currents only. It is the standard type for general-purpose circuits without electronic loads that generate pulsating DC or smooth DC fault currents.

Where can I buy 5SU9356-1CR16?

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

Will 5SU9356-1CR16 drop into a panel specified around 5SL6550-7BB?

Both are 2-module DIN-rail RCBOs, but the 5SL6550-7BB is a different rating and characteristic. The 5SU9356-1CR16 is 16 A / 30 mA / C-curve; verify the existing panel's required rating before substituting. Physical footprint is the same 36 mm width and 77 mm depth.
