Overview

The ABB DS201 C16 RCBO (Order Code: UL2CSR255187R11640.21) is a UL 1053/1077 and CSA C22.2 No. 144/235 compliant residual current circuit breaker with overcurrent protection, designed for single-phase terminal circuit applications. This advanced device integrates a 30 mA residual current device (RCD) with a Type C miniature circuit breaker (MCB), offering comprehensive protection against overload, short-circuit, and earth fault currents. The DS201 C16 provides critical protection against indirect contact and additional safety against direct contact, ensuring a secure electrical environment. Key specifications include a 16A rated current, C-curve tripping characteristic, and 30mA residual current sensitivity (IΔn). The device is suitable for residential, commercial, and industrial applications, replacing the previous DS951 UL product line while maintaining backward compatibility with System pro M compact™ accessories. Notable features include a test pushbutton for verifying correct operation, a blue flag indicator on the toggle to identify ground fault trips, and molded IΔn – 0 OFF indications for immediate status recognition. Installation is simplified by bi-directional cylindrical terminals, ensuring easier and safer connections. The DS201 C16 also includes an RFID tag for product authentication, laser-printed information for long-term readability, and a dedicated space for labels to clearly identify protected lines. Optional accessories include bottom-mount auxiliary contacts, motor operating devices, and contact position indicators. With compact dimensions of 85 x 69 x 35 mm (H x D x W) and a weight of 200g, the DS201 C16 is designed for DIN rail mounting (EN 60715, 35mm) and can be supplied from top or bottom terminals. It is mechanically compatible with a range of auxiliary elements, including auxiliary contacts, shunt trips, undervoltage releases, and overvoltage releases, though UL approval for combinations is not guaranteed.
