Reliable Protection for Low-Voltage Power Distribution
Air circuit breakers such as the ABB SACE Emax E1N are designed to switch and protect high-current low-voltage distribution circuits. By combining a robust breaker mechanism with an electronic protection unit, the circuit breaker can detect abnormal current conditions and interrupt the circuit before overloads or short circuits cause extensive damage to cables, busbars and connected electrical equipment.
The PR121/P-LSI release provides long-time overload, short-time and instantaneous short-circuit protection. Combined with the E1N breaker's high short-circuit performance and fixed horizontal-rear-terminal construction, this makes the ABB 1SDA055697R1 particularly suitable for main distribution and feeder protection in industrial and commercial switchboards.
Typical Applications
- Main low-voltage switchboards and distribution boards.
- Industrial power distribution systems.
- Commercial and infrastructure electrical installations.
- Main incomer and feeder circuit protection.
- Manufacturing and process plant switchgear.
- High-current electrical distribution and control systems.
