What this MCCB carries for a vessel or industrial panel
Breaking capacity sits at 242 kA at 240 VAC, 187 kA at 415/440 V, and 121 kA at 500 V. At 690 V it drops to 3 kA — that last figure governs if you are feeding a 690 V drive bus; the 240–500 V numbers cover most marine and industrial secondary distribution. Fits standard Siemens SENTRON mounting base; the 105 mm width matches the 3VA2 frame footprint.
Auxiliary and release configuration — what is inside the cover
The UVR drops the breaker on loss of control voltage — standard for emergency-stop chains and undervoltage protection schemes that need a positive open on power loss. If you need Modbus or GFCI, step to the 3VA2 with communication module or the 3VA2 with ground-fault option.
Environmental and installation limits
Trip indicator present; no voltage trigger. The undervoltage release is the only auxiliary release fitted — no shunt trip on this code.
