Why Choose ABB 1SDA125598R1?
The ABB 1SDA125598R1 is an E1.3N 800 Ekip Aware LI 4-pole WMP air circuit breaker from the SACE Emax 3 range, designed for reliable protection and switching in low-voltage power distribution systems.
With an 800 A rated current and an Ekip Aware LI R 800 electronic release, this withdrawable circuit breaker provides adjustable long-time and instantaneous overcurrent protection for demanding electrical distribution applications.
The 4-pole withdrawable configuration combines flexible switchgear installation with electronic protection functionality, while integrated auxiliary contacts and position indication support control, signalling and operational monitoring within compatible switchgear assemblies.
Key Advantages
- 800 A rated current: Suitable for high-current low-voltage power distribution applications.
- Ekip Aware LI protection: Provides long-time and instantaneous overcurrent protection.
- 4-pole configuration: Suitable for three-phase systems requiring neutral pole switching and protection.
- Withdrawable construction: Allows the circuit-breaker moving part to be withdrawn from the associated switchgear assembly.
- Adjustable protection settings: Long-time and instantaneous protection thresholds can be configured to suit the installation.
- Integrated auxiliary contacts: Four auxiliary contacts support electrical signalling and control functions.
- Position indication: Supports monitoring of the circuit-breaker open/closed status.
- High short-circuit performance: The E1.3N 800 platform provides 66 kA Icu at 440 V and 50 kA Icw for 1 s.

ABB SACE Emax 3 E1.3N 800 Protection
The 1SDA125598R1 combines the E1.3N 800 circuit-breaker platform with ABB's Ekip Aware LI electronic release. The LI protection configuration provides adjustable long-time and instantaneous protection, helping coordinate the circuit breaker with the electrical characteristics and protection requirements of the distribution system.
Its 320–800 A long-time setting range and 1200–12000 A instantaneous setting range provide flexibility when configuring protection for downstream equipment and distribution circuits. The E1.3N performance class provides 66 kA Icu at 440 V and 50 kA Icw for 1 s, supporting applications where high fault-current withstand capability is required.
The withdrawable WMP configuration is designed for use within compatible SACE Emax 3 switchgear assemblies, allowing the moving part of the air circuit breaker to be withdrawn for suitable maintenance and operational procedures. Four auxiliary contacts and open/closed position indication further support switchgear control and monitoring requirements.
