For a 415 V distribution board feeding motor control centers or lighting, that rating covers most downstream faults up to that level, so you don't cascade the trip upstream to the main breaker. The thermal-magnetic trip unit is a TM240 with ATAM (adjustable thermal, adjustable magnetic). Overload protection (Ir) is adjustable from 56 A to 80 A, and short-circuit protection (Ii) from 5 to 10 times In (400 A to 800 A). The N conductor is unprotected on this variant, meaning the neutral pole is a switched-only pass-through with no overload or short-circuit sensing. That's standard for a 4-pole breaker feeding a balanced three-phase load where the neutral carries only imbalance current.
The -ZD00 suffix indicates a special OEM configuration for DC Power in China — that means the breaker carries a custom marking or accessory kit, not a different electrical rating. If your BOM calls for the standard 3VA1180-3EF42-0AA0 without the suffix, verify the OEM-specific differences before substituting.
