Siemens CDT3B050 U is a three-pole molded‑case circuit breaker (MCCB) rated for 50 A in three‑phase electrical systems, designed for operation up to 600 V AC. It protects three‑phase feeders in industrial and commercial panels, offering reliable interruption for faults on circuits up to the rated current. The compact 3P frame fits standard distribution boards and motor‑control centers where 50 A protection is required, and is part of Siemens' CDT3B family of general‑purpose MCCBs used for branch‑circuit protection in industrial installations.
