The Siemens 3VA1110-3EF36-0JA0 is a 3-pole IEC frame 160 molded case circuit breaker with a 25 kA breaking capacity at 415 V (class N). It is rated In=100 A continuous current, with an adjustable thermal overload protection range (Ir) of 70 A to 100 A and a fixed short-circuit magnetic trip (Ii) set at 5 to 10 times In. The breaker includes a shunt trip (STL) release for remote tripping, rated 110-127 V DC or AC 50/60 Hz.
The adjustable Ir (70-100 A) lets you match the overload protection to the actual load cable or motor FLA without swapping the breaker body.
Panel integration
Clamp-type terminals accept copper or aluminum conductors without lug kits. The 3VA1 frame fits standard Siemens panelboard and switchboard mounting patterns. The shunt trip occupies the accessory slot on the left side; no additional wiring space is needed beyond the breaker's own line/load terminals.
