The overload protection is set at a fixed Ir=20 A, with short-circuit protection fixed at Ii=16 x In (320 A). Because both are fixed — not adjustable — this breaker is a straight drop-in for a 20 A branch circuit where you don't need field tuning. The TM210 curve provides a thermal-magnetic response: thermal for sustained overloads, magnetic for instantaneous shorts. The 16kA @ 415 V SCCR means it can be applied on a 415 V supply with available fault current up to that value without requiring an upstream current-limiting fuse or breaker. ## Integration and connections The breaker uses clamp (screw) connections, which accept copper or aluminum conductors up to the frame's rated wire range. It ships with three factory-installed auxiliary switches (HQ type) for remote status indication — useful for PLC inputs or alarm annunciation.","metaTitle":"Siemens 3VA1020-2ED36-0AD0 Circuit Breaker, 20A, 16kA @ 415V","metaDescription":"Siemens 3VA1020-2ED36-0AD0 IEC frame 100 circuit breaker, 20A fixed thermal-magnetic, 16kA breaking capacity @ 415V.
