At 240 V it interrupts 187 kA; at 415 V / 440 V it holds 121 kA, and at 690 V the interrupting rating drops to 7.5 kA, so the available fault current at the installation point must be verified against the voltage-specific curve. The line-protection design targets main incomers and large feeders, not branch motor circuits. Built-in communication and other measurement functions allow integration into a plant monitoring system — the exact protocol is set by the plug-in communication module (not included in this base order code). ## Temperature Derating & Continuous Current The 400 A rating holds up to 50 °C ambient. Above that the breaker must be derated: 375 A at 55 °C, 350 A at 60 °C, 325 A at 65 °C, and 300 A at 70 °C (–). ## Auxiliary Switches & Undervoltage Release The basic switch assembly is order code 3VA2340-5KP32-0AA0; the UVR and aux switches are factory-integrated, not field-addable on this SKU. ## Dimensions & Panel Fit Footprint: 138 mm wide × 248 mm high × 110 mm deep (–). That 110 mm depth (4.33 in) is shallow for a 400 A frame — fits in a 250 mm deep enclosure with room for rear cable lugs. Width of 138 mm (5.43 in) means a 3-pole unit occupies about 5.5 module spaces on a DIN rail; plan the backpanel layout accordingly.","metaTitle":"Siemens 3VA2340-5KP32-0DH0 SENTRON MCCB, 400 A, Adjustable 6","metaDescription":"Siemens SENTRON 3VA2340-5KP32-0DH0 molded case circuit breaker, 400 A continuous, adjustable trip 600-4000 A, 3-pole, 187 kA at 240 V.
