1SDA073362R1 ABB E6.2H/f 6300 Ekip Dip LSI 4p WMP Air Circuit Breaker

Why Choose the ABB E6.2H/f 6300 Ekip Dip LSI 4p WMP Air Circuit Breaker?

The ABB E6.2H/f 6300 Ekip Dip LSI 4p WMP, order code 1SDA073362R1, is a high-capacity four-pole withdrawable air circuit breaker moving part from the ABB SACE Emax 2 range. Designed for demanding low-voltage power distribution systems, it combines a rated uninterrupted current of 6300 A with an Ekip Dip LSI electronic trip unit providing long-time overload, short-time selective short-circuit and instantaneous short-circuit protection.

The E6.2H/f full-size configuration is engineered for major switchboards where very high current capacity, dependable fault interruption and protection selectivity are essential. Its fully rated fourth pole makes it suitable for demanding four-pole distribution applications, while the withdrawable architecture enables the moving portion to be disconnected from the main circuit using the appropriate Emax 2 fixed part for inspection, maintenance or replacement.

With a rated uninterrupted current of 6300 A and an H-class rated ultimate short-circuit breaking capacity of 100 kA at 440 V AC, the E6.2H/f 6300 is designed for high-power electrical installations. Its rated short-time withstand current of 100 kA for 1 s supports selective protection strategies in complex industrial and infrastructure distribution networks.

Selective High-Current Protection for Critical Power Distribution

Air circuit breakers such as the ABB Emax 2 E6.2H/f provide switching, isolation and electrical protection for major low-voltage distribution systems. The combination of a 6300 A current rating, 100 kA short-circuit breaking capacity and 100 kA short-time withstand capability makes this breaker particularly suitable for main incomers, transformer secondary circuits, bus couplers and other high-current circuits in large switchboards.

The Ekip Dip LSI electronic release provides adjustable long-time protection against sustained overload conditions, short-time protection for selective coordination and instantaneous protection against severe short-circuit faults. Combined with the Emax 2 withdrawable architecture, the E6.2H/f 6300 provides a practical solution for installations requiring very high current capacity, dependable fault protection and maintainable switchgear.

Typical Applications

• Main incomers in very high-current low-voltage switchboards.
• Industrial power distribution systems.
• Transformer secondary protection.
• Bus couplers and bus-tie circuit breaker applications.
