Why Choose the ABB E3H 800 PR122/P-LI Air Circuit Breaker?
The ABB E3H 800 PR122/P-LI, order code 1SDA056347R1, is a high-performance SACE Emax air circuit breaker (ACB) designed for switching and protection in demanding low-voltage power distribution systems. This four-pole fixed version has a rated current of 800 A and combines the E3H breaker platform with a PR122/P-LI R800 electronic overcurrent release.
The PR122/P-LI R800 electronic trip unit provides long-time overload and instantaneous short-circuit protection. Its electronic protection technology helps safeguard conductors, switchgear and connected equipment against sustained overcurrents and severe short-circuit faults while allowing protection settings to be matched to the distribution system.
The breaker features a four-pole fixed configuration with rear horizontal terminals, making it suitable for permanent integration into switchboards and busbar systems. Its H performance level provides an ultimate short-circuit breaking capacity of 100 kA at 400–415 V AC, while four auxiliary contacts and open/closed position indication support switchboard signalling and control.
Key Advantages
- Heavy-duty 800 A SACE Emax air circuit breaker.
- PR122/P-LI R800 electronic overcurrent release for dependable circuit protection.
- LI functions provide long-time overload and instantaneous short-circuit protection.
- Four-pole fixed configuration for permanent switchboard installation.
- Rear horizontal terminals support practical connection to switchboard busbars.
- 100 kA ultimate breaking capacity at 400–415 V AC for high-fault-level distribution systems.
Key Features
- ABB SACE Emax E3H series.
- 800 A rated uninterrupted current.
- 690 V AC rated operational voltage.
- PR122/P-LI R800 electronic trip unit.
- Long-time overload protection.
- Instantaneous short-circuit protection.
- Four-pole fixed construction.
- Rear horizontal terminal arrangement.
- 100 kA Icu at 400–415 V AC.
- 75 kA rated short-time withstand current for 1 s.
- Four auxiliary contacts.
- Open/closed circuit-breaker position indication.
High-Breaking-Capacity LI Protection
The PR122/P-LI release provides two essential protection functions for high-current electrical networks. Long-time protection responds to sustained overload conditions, while instantaneous protection rapidly opens the circuit breaker when severe short-circuit current exceeds the configured threshold.
Combined with the E3H high-breaking-capacity platform, this protection makes the 1SDA056347R1 suitable for distribution systems with substantial prospective fault currents. Its four-pole fixed construction and rear horizontal terminals provide a practical arrangement for integration into main switchboards and industrial busbar systems.
Typical Applications
- Main low-voltage distribution switchboards.
- Industrial power distribution systems.
- Manufacturing and process plants.
- Commercial and infrastructure electrical installations.
- Transformer-fed four-wire distribution systems.
- High-fault-level switchgear and distribution assemblies.
