FAQs
Install the four-pole, fixed-connection MCCB with front terminals into the panel per the manufacturer's mounting guidelines. Align with the DC bus, tighten terminals to secure the front-access wiring, and verify the device is properly seated to maintain insulation and clearance. Ensure the rated current (16 A) and voltage (500 V DC) match the circuit being protected and check that the release (TMD) is correctly configured for the load type.
For the ABB 1SDA123552R1, the rated service short-circuit current Ics is up to 85 kA with 250 V DC (2 poles in series) and up to 85 kA with 500 V DC (3 poles in series). The rated ultimate short-circuit current Icu conforms to the same configuration-based values. This ensures robust protection for high fault currents in DC networks.
Yes. The 1SDA123552R1 is designed for DC protection in applications such as PV DC networks and motor drives, offering a 500 V DC operating range and a 16 A rating.
