Why Choose the ABB 1SDA059215R1 E1N 1000 Air Circuit Breaker?
The ABB 1SDA059215R1 is a SACE Emax E1N 1000 air circuit breaker designed for dependable protection and switching in industrial low-voltage power-distribution systems. This four-pole fixed version is rated at 1000 A and is equipped with ABB's PR121/P-LI R1000 electronic overcurrent release.
The PR121/P-LI provides long-time (L) overload and instantaneous (I) short-circuit protection. Its adjustable overload setting covers 400–1000 A, while the instantaneous short-circuit setting covers 1500–15000 A, allowing the breaker protection to be coordinated with the requirements of the connected distribution system.
The 1SDA059215R1 combines its E1N performance level with a rated ultimate short-circuit breaking capacity of 50 kA at 400 V AC. Its fixed construction uses rear horizontal terminals, while four auxiliary changeover contacts and open/closed indication support integration into switchboard signalling and control systems.
Key Advantages
- 1000 A E1N air circuit breaker for substantial industrial distribution duties.
- PR121/P-LI R1000 electronic release provides long-time overload and instantaneous short-circuit protection.
- 50 kA ultimate short-circuit breaking capacity at 400 V AC.
- Four-pole configuration for compatible four-conductor distribution systems.
- Fixed construction for permanent switchboard installation.
- Rear horizontal terminals provide a defined main-circuit connection arrangement.

Reliable LI Protection for Industrial Power Distribution
The ABB PR121/P-LI electronic release provides two fundamental protection functions for industrial distribution circuits. Long-time protection responds to sustained overload conditions, while instantaneous protection provides rapid tripping when severe short-circuit currents occur, helping protect conductors and connected equipment against damaging fault energy.
Combined with the E1N breaker's 1000 A current rating, 50 kA ultimate breaking capacity at 400 V AC and four-pole fixed construction, the 1SDA059215R1 provides a robust solution for switchboards requiring adjustable electronic protection, substantial fault-interruption capability and permanent rear-connected installation.
Typical Applications
- Industrial low-voltage main distribution boards.
- Main incomer and feeder protection.
- Transformer secondary distribution.
- Four-pole industrial distribution systems.
- Manufacturing and process plant switchgear.
- Commercial and infrastructure power distribution.
- High-fault-level low-voltage networks.
- OEM fixed switchboard assemblies.
