It carries a rated current of 50 A across the 40 °C to 50 °C ambient range, with slight derating above that — 49 A at 55 °C, down to 45 A at 70 °C. The basic switch supplied is order code 3VA11504EF320AA0.
This breaker's interrupting capacity varies sharply with system voltage, which is typical for MCCBs. At 240 V it can clear 121 kA — plenty for most low-voltage service entrances. At 415 V it's rated 75.6 kA, at 440 V it drops to 52.5 kA, and at 500 V and 690 V it holds at 11.9 kA.
The 3-pole design occupies three modular width units (each ~25.4 mm). The shunt trip (STL) and auxiliary switch block are pre-installed, so no field assembly of accessories is needed — just wire the line and load lugs, connect the shunt trip control voltage, and land the auxiliary contacts into your PLC or status indication circuit.
