Advanced Circuit Protection for High-Current Power Distribution

Air circuit breakers such as the ABB E6L-A protect high-current low-voltage distribution systems against abnormal operating conditions. By interrupting the circuit when configured protection thresholds are exceeded, the breaker helps protect cables, busbars, switchgear and connected electrical equipment against damage caused by overloads, short circuits and ground faults.

The PR121/P-LSIG electronic release provides long-time, short-time, instantaneous and ground-fault protection for installations requiring comprehensive overcurrent protection and selective coordination. Combined with the E6L-A frame's 5000 A current rating and fixed construction, this makes the 1SDA061307R1 particularly suitable for major industrial switchboards and high-capacity power distribution systems.

Typical Applications

• High-capacity 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.
