Breaking capacity and protection curve
This 3VA1163-6ED42-0AA0-ZD00 is a 4-pole IEC frame 160 molded case circuit breaker with a 70 kA interrupting capacity at 415 V (breaking capacity class H). Overload protection is set by a fixed TM210 thermal-magnetic trip unit: Ir = 63 A fixed (no adjustment), short-circuit pickup Ii = 10 × In = 630 A. The fixed Ir suits dedicated loads where the breaker is sized to the conductor, not to a variable motor FLA. The 10 × In magnetic pickup rides through moderate inrush on resistive or lightly inductive circuits. The N conductor is unprotected — the fourth pole is a switched neutral without overload or short-circuit protection. The nut keeper kit (included) is specified for DC Power OEM applications in China, indicating this variant ships with hardware for panel builders assembling DC distribution.
Mounts in a standard 3VA1 screw-fixed or plug-in base (not included). The 4-pole footprint occupies 4 × 27 mm per pole — roughly 108 mm wide on the DIN-rail adapter plate. Verify the gland plate cutout for the line and load terminals; the breaker accepts Cu/Al conductors up to 50 mm² for the main circuit.
No PCN or EOL notice is on record for this specific variant.
