High-Performance Circuit Protection for Electrical Installations
Miniature circuit breakers such as the ABB S301P-Z20NA protect electrical circuits by responding to excessive current conditions. The thermal release provides delayed protection against overloads, while the electromechanical release responds rapidly to short-circuit conditions, helping protect conductors and connected equipment.
The S300P series is designed for demanding commercial and industrial applications. Its Z tripping characteristic provides sensitive overcurrent protection for circuits where this characteristic is specified, while the high breaking capacity provides robust short-circuit protection. The 1P+N configuration also provides switched neutral isolation within a compact modular device.
Typical Applications
- Industrial electrical distribution systems.
- Commercial building distribution boards.
- Control panels and automation installations.
- AC branch circuit protection up to 20 A.
- Circuits requiring a Z tripping characteristic.
- Single-phase circuits requiring switched-neutral protection.
