Product details

The 5SU1353-1KL32: Rated at 32 A at 30 °C ambient, it derates to 24.64 A at 70 °C — the thermal curve matters if the panel runs hot. Breaking capacity is 4.5 kA per EN 60898 and 5 kA per IEC 60947-2, so it's sized for residential and light commercial distribution boards, not high-fault industrial mains. Supply can enter from top or bottom; mounting position is any. The IP20 rating applies once installed in a distribution board with conductors connected — it's not a standalone enclosure part.

The 5SU1353-1KL32 is listed as current-production (active lifecycle stage). It's sourced through the standard Siemens distribution channel; we quote to order against an RFQ.

Frequently asked questions

What is the breaking capacity of 5SU1353-1KL32?

4.5 kA per EN 60898 and 5 kA per IEC 60947-2.

Where can I buy 5SU1353-1KL32?

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

Does 5SU1353-1KL32 fit a panel designed for 5SU9354-7KK16?

Both are 2-module-width (36 mm) DIN-rail RCBOs, so the mechanical footprint is the same. Verify the residual current rating and trip characteristic of the peer before substituting — the evidence does not confirm identical electrical ratings.
