It carries a 187 kA interrupting capacity at 240 VAC and 121 kA at 415/440 VAC, which puts it in the high-fault category for industrial distribution panels and motor control centers where available fault current is significant. The 187 kA at 240 VAC and 121 kA at 415 VAC are the ultimate short-circuit breaking capacities (Icu) per IEC 60947-2. At 500 VAC it still clears 75.6 kA, and at 690 VAC the rating drops to 3.7 kA — a steep fall that reflects the arc-extinction challenge at higher voltages. For a 480 VAC panel (common in North America), the 75.6 kA at 500 VAC is the closest reference; for 400 VAC systems (Europe/Asia), the 121 kA at 415 VAC applies. ## Trip unit and auxiliary configuration The ETU320 electronic trip unit is the overcurrent release on this variant. It supports LSI protection (long-time, short-time, instantaneous) with adjustable pickups and time delays, which is what you need for selective coordination downstream of a transformer or upstream of feeder breakers. The basic switch order code is 3VA21405HL320AA0, which is the internal switching mechanism; the full breaker includes it. The breaker is designed for screw-mounting to a backplate or mounting plate, not DIN rail.","metaTitle":"Siemens 3VA2140-5HL32-0AB0 SENTRON MCCB, 40 A, 3-Pole, 187 k","metaDescription":"Siemens SENTRON 3VA2140-5HL32-0AB0 molded case circuit breaker, 40 A rated, 3-pole, ETU320 release, 187 kA breaking at 240 VAC.
