Breaking capacity hits 440 kA at 240 VAC, 330 kA at 415 V, and still delivers 220 kA at 500 V; at 690 V it holds 52.5 kA. That means it clears high-fault scenarios in industrial distribution without cascading upstream — line protection design for heavy plant feeds. ## ETU340 trip unit — what it controls It's a straight line-protection MCCB: trip indicator absent, no auxiliary contacts on the base unit. Footprint: 138 mm wide, 248 mm tall, 110 mm deep. Bolts into a standard MCCB panel cutout — no DIN-rail mount, this is a fixed breaker. Verify the bus-bar spacing and lug kit compatibility when replacing a previous frame.","metaTitle":"3VA2440-8HK32-0AA0 SENTRON MCCB, 400 A, 440 kA at 240 V","metaDescription":"Siemens SENTRON 3VA2 MCCB, 3-pole, 400 A continuous, 440 kA breaking at 240 VAC.
