Description

The ABB 1SDA066557R1 is a robust 4-pole moulded-case circuit breaker (MCCB) from ABB’s SACE FORMULA A2B range. Rated for 200 A, it uses a TMF (thermo-magnetic fixed) trip unit with a wide setting range (200 – 2000 A) for reliable overload and short-circuit protection. 

With fixed front terminals for secure mounting, this breaker has an ultimate breaking capacity (Icu) of up to 25 kA at 240 V AC and 18 kA at 380–415 V AC. 

 It is compliant with IEC 60947-2 standards and is built to withstand up to 10,000 mechanical operations and 4,000 electrical cycles. 

Compact and reliable, this MCCB is ideal for power-distribution panels in industrial, commercial, or infrastructure applications, offering dependable protection without taking up excessive space.
