Advanced Circuit Protection for Power Distribution

Air circuit breakers such as the ABB E4L-A protect high-current electrical distribution systems against abnormal operating conditions. By automatically interrupting the circuit when configured protection thresholds are exceeded, the breaker helps protect cables, busbars, switchgear and connected equipment from damage caused by overloads and short circuits.

The PR123/P-LSIG electronic release provides comprehensive protection functionality for installations where selective coordination and ground-fault protection are required. Its combination of long-time, short-time, instantaneous and ground-fault functions makes the E4L-A particularly suitable for critical industrial switchboards and high-capacity low-voltage distribution systems.

Typical Applications

• Low-voltage main distribution switchboards.
• Industrial power distribution systems.
• Manufacturing and process plants.
• Large commercial and infrastructure installations.
• Transformer secondary protection.
• Generator and power distribution systems.
• High-current switchgear assemblies.
• Electrical installations requiring selective LSIG protection.
