Why Choose ABB 1SDA125584R1?
The ABB 1SDA125584R1 is an E1.3N 630 Ekip Aware LSI 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 a 630 A rated current and an Ekip Aware LSI R 630 electronic release, this withdrawable circuit breaker provides adjustable long-time, short-time and instantaneous overcurrent protection for demanding electrical distribution applications.
The 4-pole withdrawable configuration combines flexible switchgear installation with advanced electronic protection functionality, while auxiliary contacts and position indication support control, signalling and operational monitoring within compatible switchgear assemblies.
Key Advantages
- 630 A rated current: Suitable for high-current low-voltage power distribution applications.
- Ekip Aware LSI protection: Provides long-time, short-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- Withdrawable construction: Allows the circuit-breaker moving part to be withdrawn from the associated switchgear assembly.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: Protection thresholds can be configured to suit the requirements of the electrical installation.
- Short-time protection: Supports selective coordination between upstream and downstream protective devices.
- 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 630 platform provides 66 kA Icu at 440 V and 50 kA Icw for 1 s.

ABB SACE Emax 3 E1.3N 630 Protection
The 1SDA125584R1 combines the E1.3N 630 circuit-breaker platform with ABB's Ekip Aware LSI electronic release. The LSI protection configuration provides adjustable long-time, short-time and instantaneous protection, helping coordinate the circuit breaker with the electrical characteristics and protection requirements of the distribution system.
Its 252–630 A long-time setting range and 945–9450 A instantaneous setting range provide flexibility when configuring protection for downstream equipment and distribution circuits. The additional short-time protection function can assist with selective coordination where discrimination between protective devices is required.
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.
