The DS201 B16 A30 is a 2-pole RCBO — a combined overcurrent and residual-current device — rated 16 A with a B-curve trip characteristic and a 30 mA earth-leakage threshold. The 30 mA residual-current element protects against direct-contact shock and ground faults. On a DIN-rail panel, this unit occupies a 35 mm width and 85 mm height, with a depth of 69 mm — standard for compact RCBOs. The IP2X (finger-safe) front and IP4X (splash-protected) enclosure allow installation in distribution boards without additional shrouding.
