Product overview
The Siemens SENTRON 3VA1080-3ED36-0BA0 is a 3-pole molded case circuit breaker (MCCB) rated for line protection, with an 80 A continuous current rating at 40 °C and a TM210 thermal-magnetic overcurrent release. Breaking capacity reaches 75.6 kA at 240 V AC, 52.5 kA at 415 V, 32 kA at 440 V, and 7.5 kA at both 500 V and 690 V — giving solid fault-clearing headroom across common industrial voltage levels.
Current rating holds at 80 A from 40 °C up to 50 °C, then derates to 78 A at 55 °C, 77 A at 60 °C, 75 A at 65 °C, and 74 A at 70 °C — useful when the breaker sits in a warm enclosure or near other heat sources.
