What this MCCB delivers
The Siemens 3VA2063-6HL36-0AA0 is a SENTRON molded case circuit breaker rated for 63 A continuous current across the full ambient range from 40 °C to 70 °C — no derating needed up to that ceiling (–,). Its ETU320 electronic overcurrent release handles line protection, with a maximum breaking capacity of 242 kA at 240 V and 187 kA at 415 V (–). That SCCR headroom means it can interrupt high-fault currents without cascading upstream, critical for main feeders or high-capacity distribution panels.
Fit and integration
The 3VA2063-6HL36-0AA0 measures 105 mm wide, 181 mm tall, and 86 mm deep — a compact 3-pole footprint that fits standard SENTRON mounting bases and panel cutouts (–, –). Front IP40 protection suits enclosed panel installations; no communication module or undervoltage release is fitted, so it's a straightforward line-protection breaker without auxiliary wiring. Operating range spans -25 °C to 70 °C, storage from -40 °C to 80 °C (–).
