Product details

It combines a Type A residual-current device (RCD) rated at 30 mA with a C-curve miniature circuit breaker (MCB) rated at 20 A, all in one DIN-rail unit.

Deployment context

Snap-on DIN-rail mounting for a standard distribution board or sub-distribution enclosure. The 1-module width (roughly 18 mm) saves rail space compared to separate RCD + MCB pairs. Rated for 230 VAC single-phase final circuits — typical use is protecting a lighting circuit, a socket outlet circuit, or a small appliance circuit in residential, commercial, or light industrial panels where both earth-leakage and overcurrent protection are required in one device.

Frequently asked questions

What are the key ratings of 5SU9336-7CR20?

This RCBO is rated Icn 6 kA, 1P+N, Type A RCD at 30 mA, C-curve MCB at 20 A, and Un AC 230 V. The Type A RCD covers pulsating DC faults from electronics, and the C-curve handles moderate inrush loads.
