Thermal derating is published across the full operating range: the breaker carries a full 400 A up to 50 °C ambient, then steps down to 384 A at 55 °C, 376 A at 60 °C, 368 A at 65 °C, and 360 A at 70 °C. For a panel builder sizing a main breaker in a non-climate-controlled enclosure, the 55 °C column is often the real-world rating — 384 A continuous, not the nameplate 400 A. The integrated undervoltage release (UVR) allows a safety circuit to trip the breaker on loss of control voltage — a common requirement for emergency-stop chains and power-management systems. ## Lifecycle and sourcing — current production, quoted to order The 3VA2440-6HL32-0CL0 carries the SENTRON branding and is designed to IEC 60947-2 and UL 489 standards. The ETU320 trip unit is field-configurable for LSI protection curves, which gives the specifying engineer flexibility to adjust long-time, short-time, and instantaneous pickup thresholds without swapping hardware. ## Panel integration — footprint and mounting Dimensions are 248 mm height × 138 mm width × 110 mm depth. The 138 mm width fits a standard 3-pole MCCB cutout in a distribution board. Maximum power loss is 66 W, which should be factored into the enclosure thermal budget — particularly when multiple breakers are ganged in a sealed cabinet. The part is not conformally coated as standard, so for marine or high-humidity environments, verify the enclosure rating separately.","metaTitle":"Siemens 3VA2440-6HL32-0CL0 SENTRON MCCB, 400A, 3-Pole, ETU32","metaDescription":"Siemens SENTRON 3VA2440-6HL32-0CL0 molded case circuit breaker. 400 A rated, 3-pole, ETU320 line protection, 242 kA at 240 V.
