SENTRON 3VA1040-4ED32-0JH0 — 40 A MCCB with 121 kA interrupting capacity
Three poles, rated 40 A continuous at 40 °C ambient, with no derating needed up to 50 °C — still holds 40 A at 50 °C. Interrupting capacity is the headline number here: 121 kA at 240 V, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at both 500 V and 690 V. That 121 kA at 240 V gives serious fault-current headroom for industrial distribution — typical panel SCCR requirements in the 65–100 kA range are comfortably covered. At 415 V the 75.6 kA rating still handles most high-fault service-entrance applications.
Dimensions: 130 mm tall, 76.2 mm wide, 70 mm deep — standard 3-pole MCCB footprint. No undervoltage release on this variant — if you need UVR protection, this isn't the order code.
