A shunt trip (STL) is built in, letting a remote signal or emergency-stop circuit trip the breaker without a human pulling the handle. Inside a locked enclosure that's fine; out in a washdown zone you'd want an IP65-rated cover over it.
Breaking capacity — what it can interrupt at your system voltage
This MCCB's interrupting rating depends on the system voltage you're feeding it. At 240 V it clears 75.6 kA; at 415 V it handles 52.5 kA; at 440 V it's rated for 32 kA; and at 690 V it still interrupts 7.5 kA.
Thermal derating — how hot can the panel get before you lose ampacity
At 55 °C it derates to 48 A, at 60 °C to 47 A, at 65 °C to 46 A, and at 70 °C to 45 A.
Physical fit and mounting
The breaker measures 130 mm high, 76.2 mm wide (that's three standard 25.4 mm module widths), and 70 mm deep.
