Rated for AC/DC supply voltage and classified in overvoltage category 3, it handles fixed-installation transients typical of building and industrial final circuits. Energy limiting class 3 means it restricts let-through energy well, aiding downstream device protection during a fault. ## Panel integration Snap-on DIN rail mounting, 3 width units (approx. 54 mm), 55 mm installation depth. The neutral conductor is not switched through the breaker — neutral bar remains separate. Verify busbar compatibility for 3-pole spacing before assembly.","metaTitle":"SENTRON 5SQ2370-0KA25 Circuit Breaker, 3-Pole C 25A, 3kA","metaDescription":"SENTRON 5SQ2370-0KA25 miniature circuit breaker, 3-pole, C-curve, 25 A rated current, 3 kA breaking capacity at 400 V AC, 50 Hz.
