Siemens 3VA1 IEC frame 160 circuit breaker, breaking capacity class M, Icu=55kA @ 415V, 4-pole, line protection TM240, ATAM, In=20A, overload protection Ir=14A...20A, short-circuit protection Ii=8...16 x In.
The 55kA Icu at 415V makes it suitable for main or branch protection in industrial panels where the available fault current exceeds typical 25kA or 36kA ratings — common in large manufacturing plants or utility-scale solar farms where transformer impedance is low.
This configured OEM variant is sourced to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.
The ultimate breaking capacity Icu is 55kA at 415V, placing it in breaking capacity class M for high-fault industrial applications.
Overload protection Ir is adjustable from 14A to 20A, and short-circuit protection Ii is adjustable from 8 to 16 times the rated current In=20A.
