Overview
The ABB S202-Z6 circuit breaker is part of ABB’s proven S 200 series miniature circuit breakers (MCBs). The model 2CDS252001R0378 delivers dependable protection in two-pole, single-phase, or split-phase AC circuits. With a 6A rated current and Z-type trip characteristic, this breaker is engineered for applications requiring selective protection against overloads and short circuits.
Key Features
- 2-pole configuration for single-phase or split-phase distribution
- Z characteristic trip curve optimized for inductive loads and motor circuits
- DIN 46277 rail mounting (35 mm standard) for quick installation and removal
- Up to 6 kA breaking capacity at 230/400V AC per S 200 series design
- Compact form factor suitable for space-constrained enclosures
- Field-proven reliability in industrial, commercial, and institutional settings
