Four poles in a single 70 mm-deep module occupy 4 width units on the DIN rail; the any-position mounting and IP20 (with conductors connected) fit standard enclosure layouts. C-curve means the magnetic trip activates between 5 and 10 times rated current (160–320 A), so it holds through the starting surge of a 7.5 kW motor but clears a bolted fault in under 10 ms. Ambient temperature range –20 to +45 °C; above 45 °C the thermal trip element shifts — derate per the manufacturer's curve if the enclosure runs hot. The sealable feature (yes) allows a lead seal or wire lock through the toggle to prevent unauthorized switching — useful for safety-isolation points or rental-metered circuits. Depth of 70 mm leaves clearance for wiring ducts and gland plates in a 200 mm-deep enclosure. Overvoltage category 3 suits fixed-installation distribution boards. Vibration resistance rated at 50 m/s² from 25 to 150 Hz and 60 m/s² from 10 to 150 Hz per IEC 60068-2-6 — holds calibration on machine-tool or conveyor panels subject to continuous vibration. Mechanical endurance of 20 000 switching cycles typical for the class.","metaTitle":"Siemens 5SJ6432-7 SENTRON MCB, 4P C 32A 6kA 400V","metaDescription":"Siemens SENTRON 5SJ6432-7 miniature circuit breaker, 4-pole, C-curve, 32 A, 6 kA breaking capacity per EN 60898, 400 V AC.
