That interrupting figure drops to 187 kA at 415 V and 440 V, and to 121 kA at 500 V — still well above typical fault levels for most industrial distribution panels. At 690 V it holds 7.5 kA, which is the limit for that voltage tier. It includes a communication function, which lets the panel communicate trip status, current draw, and alarm conditions to a PLC or SCADA system without separate metering. ## Thermal derating — where the 400 A rating holds and where it tapers At 55 °C it derates to 375 A, at 60 °C to 350 A, at 65 °C to 325 A, and at 70 °C to 300 A. The 3VA1110-5EF32-0AM0 is a physically smaller frame and will not drop into a panel wired for the 3VA2340-6JP32-0HH0 without busbar and lug changes. The 3VA2340 frame uses larger line and load terminals rated for the full 400 A path; the 3VA1110 terminals are sized for lower current.","metaTitle":"Siemens 3VA2340-6JP32-0HH0 SENTRON MCCB, 400A, 242kA at 240V","metaDescription":"Siemens 3VA2340-6JP32-0HH0 SENTRON molded case circuit breaker, 400A continuous, 242kA interrupting at 240V. 3-pole line protection with communication.
