Line protection MCCB with TM240 release
The interrupting capacity reaches 121 kA at 240 V AC, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at 690 V — figures that govern selectivity coordination in a distribution panel. The TM240 release is a fixed thermal-magnetic type — no adjustable thermal or magnetic settings. The thermal element holds 20 A flat from 40 °C through 50 °C, then derates to 19.2 A at 55 °C, 18.8 A at 60 °C, 18.4 A at 65 °C, and 18 A at 70 °C.
The breaker measures 76.2 mm wide, 130 mm tall, and 70 mm deep — a standard 3-pole MCCB footprint that fits Siemens SENTRON 3VA mounting accessories and busbar systems. No rewiring is needed when swapping into a panel originally specified for a 3VA1110-5EE32-0JA0 — the mounting hole pattern, busbar pitch, and terminal layout are identical across the 3VA11xx frame sizes; the difference is in the release type and interrupting rating, not the mechanical envelope.
