This thermal stability across a 30 K band means the breaker does not force a frame-size upsizing for most panel ambient conditions; the 500 A rating is usable up to 50 °C without derating. Breaking capacity is specified per voltage: 242 kA at 240 V, 187 kA at both 415 V and 440 V, 121 kA at 500 V, and 9 kA at 690 V. ## ETU560 Electronic Trip Unit — What It Means for Coordination The overcurrent release is the ETU560, an electronic trip unit with communication function. Electronic trip units give you adjustable long-time, short-time, instantaneous, and ground-fault pickup and delay settings — not just the fixed thermal-magnetic curve of a standard MCCB. That adjustability is what makes selective coordination achievable downstream: you can set the short-time delay to ride through downstream faults up to the breaker's short-time withstand (6 kA for 1 s, per) without tripping the main. The 3-pole construction is standard for three-phase line protection. The ground-fault monitoring version uses summation current formation on the L-conductor — meaning it measures vector sum of the phase currents to detect leakage, not a separate neutral CT. Dimensions are 248 mm height, 138 mm width, 110 mm depth. The 138 mm width is the 3-pole frame width — verify the mounting footprint against your existing switchboard or panel cutout. Maximum power loss is 99 W — account for that heat in the panel thermal calculation, especially if the breaker is enclosed with other heat sources.","metaTitle":"Siemens 3VA2450-6JQ32-0AA0 SENTRON MCCB, 500 A, 242 kA at 24","metaDescription":"Siemens SENTRON 3VA2450-6JQ32-0AA0 molded case circuit breaker, 500 A continuous, 242 kA breaking at 240 V.
