ABB Emax 3 E1.3N 800 Ekip Aware LSI Protection
The ABB 1SDA125599R1 forms part of the SACE Emax 3 E1.3N 800 family and uses an Ekip Aware LSI electronic release. The LSI protection arrangement provides adjustable long-time, short-time and instantaneous overcurrent protection, allowing the breaker to be configured to suit the protection and discrimination requirements of the electrical installation.
With an I1 adjustment range of 320–800 A and an I3 adjustment range of 1200–12000 A, the device provides flexibility when coordinating protection across high-capacity low-voltage distribution networks. The E1.3N version provides an Icu of 66 kA at 440 V and an Icw of 50 kA for 1 s, supporting applications requiring robust short-circuit performance.
The four-pole withdrawable moving-part construction enables the circuit breaker to be removed from the connected installation for maintenance and servicing. Four auxiliary contacts and open/closed position indication also support control, signalling and operational monitoring within compatible switchgear assemblies.
Typical Applications
- Industrial low-voltage switchboards
- Commercial power distribution systems
- Manufacturing and process facilities
- Large electrical distribution panels
