What this 3VA1 MCCB carries
The Siemens 3VA1110-6ED32-0JA0 is a 3-pole IEC frame 160 molded case circuit breaker with a 100 A fixed thermal-magnetic trip unit (TM210). Overload protection Ir is fixed at 100 A; short-circuit protection Ii is fixed at 10 x In (1000 A). This order code includes a factory-installed left-side shunt trip accessory rated 110–127 V AC 50/60 Hz / DC. The shunt trip allows remote or emergency-off tripping from a pushbutton, PLC output, or safety relay, which is common in machine disconnect or conveyor line-stop circuits.
Availability is through normal Siemens distribution channels.
Frame 160 means the breaker body is sized for busbar or cable connections up to 160 A rated continuous current, but this unit is fitted with a 100 A trip — so the frame gives thermal headroom for high ambient or non-fan-cooled enclosures. The fixed thermal-magnetic trip (TM210) means no interchangeable trip unit; overload and short-circuit settings are not field-adjustable. That simplifies ordering but locks the protection curve — confirm 100 A continuous and 1000 A magnetic pickup match your load's inrush and cable protection requirements. The shunt trip sits on the left side of the breaker. It draws power from a separate 110–127 V AC/DC source, not the breaker's own line side. Wire it through a normally-open emergency-stop contact or PLC relay; energizing the shunt trip coil mechanically trips the breaker. Verify the control voltage matches your panel's auxiliary supply — 110 V is common in North American control transformers; 127 V appears in some IEC markets.
