Product details

The Siemens 5SU9336-1CR50 is a 3-pole RCBO combining overcurrent protection and residual current detection in a single DIN-rail mounted device. This unit sits in a standard distribution board or sub-distribution panel, consolidating two protective functions into one module width.

The C-curve (C-Char) means the magnetic trip operates at 5 to 10 times In (250–500 A for this 50 A unit), suited for circuits with moderate inrush like small motor loads or banks of fluorescent lighting.

Frequently asked questions
