Breaking capacity is 242 kA at 240 VAC, 187 kA at 415/440 V, 121 kA at 500 V, and 7.5 kA at 690 V — that 690 V number is low enough that on a 690 V line you need to verify the fault current at the point of installation doesn't exceed it. An undervoltage release (UVR) is built in, and the breaker supports communication functions — useful for remote trip indication or integration into a power-management system. ## Panel fit and mechanical constraints The basic switch variant is 3VA2340-6KP32-0AA0; this order code adds the undervoltage release and communication function on top of that base.","metaTitle":"3VA2340-6KP32-0DA0 SENTRON MCCB, 400 A, 3-Pole, 242 kA at 24","metaDescription":"Siemens SENTRON 3VA2340-6KP32-0DA0 molded case circuit breaker, 400 A continuous, 3-pole, 242 kA breaking at 240 VAC.
