The SENTRON 3VA1080-4ED36-0AD0 is a 3-pole molded case circuit breaker (MCCB) rated 80 A at 40 °C, with a TM210 thermal-magnetic overcurrent release, designed for line protection in distribution panels and industrial switchgear. Its interrupting capacity hits 121 kA at 240 V and 75.6 kA at 415 V — numbers that govern SCCR compliance downstream.
Thermal derating and auxiliary switch fit
The 80 A rating holds flat from 40 °C up to 50 °C, then tapers to 74 A at 70 °C. The breaker ships with three HQ auxiliary switches factory-fitted — no field-add kit needed for status feedback. Dimensions are 130 mm high, 76.2 mm wide, 70 mm deep — a standard SENTRON 3VA footprint that drops into existing panel cutouts and busbar arrangements without rework.
