It is a 3-pole unit rated at 16 A continuously at 40 °C ambient, with a thermal derating curve that holds 16 A up to 55 °C and drops to 15 A at 60 °C through 70 °C — useful to know when the breaker shares a crowded enclosure with other heat sources. Breaking capacity varies sharply with system voltage: 52.5 kA at 240 V, 32 kA at 415 V, 13.6 kA at 440 V, and 7.5 kA at both 500 V and 690 V. The 52.5 kA figure at 240 V is the headline number — it tells you this breaker can handle high-fault-current scenarios on low-voltage secondary sides of step-down transformers, common in North American 240/120 V distribution.
The 3VA1096-2ED32-0JC0 is available to order through independent distribution. The part is not a surplus-only find; it is a standard catalogue item in the SENTRON family.
Depth of 70 mm (2.76 in) leaves room for rear-access wiring and busbar connections in a typical 200 mm deep enclosure.
