The TM210 trip unit is fixed: overload protection Ir is locked at 40 A, and short-circuit protection Ii is fixed at 10 x In (400 A). That fixed Ir matters when you're swapping it into an existing panel: if the upstream conductor or load calculation expects a different pickup, this isn't the breaker to grab. The 36 kA @ 415 V interrupting rating is the headline number for fault duty; at 400 V (common in IEC panels) it's effectively the same, so it handles most industrial distribution boards without a series rating sticker hunt. Snap-on DIN-rail mount for the 3VA1 frame — standard 35 mm rail, no adapter plate needed. The four auxiliary switch slots let you add early-make or late-break contacts for PLC status feedback or shunt-trip supervision without drilling the enclosure for extra terminal blocks. The nut keeper kit keeps the hardware captive during installation, which saves time on the wireman's ladder when the breaker is mounted in a tight enclosure.","metaTitle":"Siemens 3VA1040-4ED32-0AE0 Circuit Breaker, 40A, 36kA @ 415V","metaDescription":"Siemens 3VA1040-4ED32-0AE0 IEC frame 100 circuit breaker, 40A fixed TM210, 36kA @ 415V breaking capacity.
