Breaking capacity hits 187 kA at 240 V, 121 kA at 415/440 V, 75.6 kA at 500 V, and 9 kA at 690 V, so it clears high-fault scenarios across common industrial voltages without cascading upstream.
No auxiliary switch or ground-fault module fitted from factory; the UVR is the only internal accessory. If you need communication or shunt trip, that is added externally via the accessory slot. Maximum power dissipation is 66 W at rated load — plan for ventilation or spacing in dense enclosures.
The depth is 110 mm (4.33 in).
As a Siemens SENTRON MCCB, it carries the manufacturer's standard declarations for RoHS, REACH, and IEC/UL certifications. Specific document copies are included with the shipment or available on request.
