At 184 mm wide, 248 mm tall, and 110 mm deep, this MCCB bolts into a standard panel footprint — no oddball cutout. The 4-pole body needs the same phase-to-phase clearance as a 3-pole unit plus neutral lug space. Above that, it drops to 385 A at 55 °C, 370 A at 60 °C, 355 A at 65 °C, and 340 A at 70 °C. If your panel runs hot near a drive bank or transformer, size the load side accordingly. Maximum power loss is 96 W, so keep ventilation paths clear.","metaTitle":"Siemens 3VA2340-5HL42-0KL0 SENTRON MCCB, 400 A, 4-Pole, Line","metaDescription":"Siemens SENTRON 3VA2340-5HL42-0KL0 molded case circuit breaker, 400 A continuous, 4-pole, 187 kA at 240 V.
