Interrupting capacity and selectivity
Interrupting capacity is 52.5 kA at 240 V AC, 32 kA at 415 V, 13.6 kA at 440 V, and 7.5 kA at both 500 V and 690 V. That 52.5 kA figure at 240 V gives headroom for high-fault panelboards downstream of a large transformer; the 7.5 kA at 690 V covers most 690 V industrial feeds.
Continuous current holds at 50 A from 40 °C through 50 °C, then derates to 49 A at 55 °C, 48 A at 60 °C, 46 A at 65 °C, and 45 A at 70 °C.
Undervoltage release and control wiring
The UVR is designated as an undervoltage release type; no voltage trigger or communication function is included. No trip indicator is fitted.
Lifecycle stage is marked current — this is an active, in-production catalog number. No successor has been issued.
Footprint is 76.2 mm wide, 130 mm tall, 70 mm deep — a standard 3-pole MCCB form factor that fits most DIN-rail or panel-mount enclosures designed for SENTRON 3VA breakers.
