Why Choose the ABB E1.2N 630 Ekip Dip LI 3-Pole Air Circuit Breaker?
The ABB 1SDA070721R1 is a SACE Emax 2 E1.2N air circuit breaker designed for reliable protection, switching and isolation in low-voltage AC power distribution systems. Rated at 630 A, this three-pole circuit breaker combines ABB's compact E1.2 frame with an Ekip Dip LI solid-state electronic trip unit.
The integrated Ekip Dip LI trip unit provides long-time (L) overload protection and instantaneous (I) short-circuit protection. This straightforward LI protection configuration makes the breaker well suited to distribution circuits where dependable overload and rapid short-circuit protection are required without short-time or ground-fault protection functions.
The 1SDA070721R1 features a three-pole fixed (F) construction with front terminals (F) and an R630 rating plug. The E1.2N platform provides an ultimate short-circuit breaking capacity of 66 kA at 400 V AC, providing robust fault-clearing performance for industrial, commercial and infrastructure switchgear applications.

Reliable Ekip Dip LI Overcurrent Protection
The ABB Ekip Dip LI trip unit provides two fundamental electronic protection functions for low-voltage distribution circuits. Long-time protection responds to sustained overload conditions, while instantaneous protection provides rapid circuit interruption when severe short-circuit currents occur.
Combined with the E1.2N breaker platform, this LI protection configuration provides a straightforward solution for circuits that do not require short-time selective or integrated ground-fault protection. The 630 A rating, fixed construction and front terminals make the 1SDA070721R1 suitable for permanent installation in appropriately designed low-voltage distribution switchboards.
Typical Applications
- Low-voltage main and sub-distribution switchboards.
- Industrial power distribution systems.
- Commercial building electrical distribution.
- Manufacturing and process plant switchgear.
- Feeder circuit protection.
- Infrastructure electrical installations.
- Three-phase systems requiring LI overcurrent protection.
- ABB SACE Emax 2 switchboard installations.
