The KETO-1 is a size-1 NH1 fuse switch-disconnector for baseplate mounting, used to isolate a DC circuit such as a battery bank while carrying overcurrent protection in the same unit. This listing is fitted with 200A NH1 fuse links; the switch body itself is rated 690V AC / 440V DC and 250A, so the 200A fuses set the circuit's protection level below the switch's own rating. Termination is by M10 bolted blade terminals accepting 25-150mm² round copper cable, tightened to 30-35Nm. Built to EN 60947-3, the KETO range is a common choice for DC disconnection and fusing in battery storage and PV installations where a compact, DIN-rail-adjacent isolator with interchangeable fuse ratings is needed.
