Why Choose the ABB E4V-A 3600 PR121/P-LSIG Air Circuit Breaker?
The ABB E4V-A 3600 PR121/P-LSIG, order code 1SDA057983R1, is a high-performance three-pole air circuit breaker (ACB) from the ABB SACE Emax range, designed for switching and protection in high-current low-voltage electrical distribution systems. Rated at 3600 A, this E4V-A breaker combines robust power switching with the PR121/P-LSIG electronic overcurrent release.
The PR121/P-LSIG trip unit provides electronic long-time (L), short-time (S), instantaneous (I) and ground-fault (G) protection. This comprehensive protection package helps safeguard conductors, switchgear and connected equipment against overload, short-circuit and earth-fault conditions in demanding electrical distribution networks.
This configuration is a three-pole fixed circuit breaker with rear horizontal terminals and a PR121/P-LSIG R3600 overcurrent release. The E4V-A 3600 has a short-circuit current rating of 100 kA at 480 V AC and a short-time current rating of 100 kA, making it suitable for high-fault-level industrial and commercial switchgear applications.

Reliable Protection for High-Current Distribution Systems
Air circuit breakers such as the ABB E4V-A protect main incoming supplies, busbars and high-current distribution feeders against potentially damaging electrical faults. Electronic trip technology monitors circuit current and initiates breaker operation when configured protection thresholds are exceeded.
The PR121/P-LSIG release extends protection to ground faults as well as overload and short-circuit conditions. Combined with the high interrupting performance of the E4V-A frame, this makes the breaker well suited to critical low-voltage switchboards where high fault levels and coordinated protection must be managed reliably.
Typical Applications
- Main incoming protection in low-voltage switchboards.
- Industrial power distribution systems.
- High-current feeder and busbar protection.
- Manufacturing and process plant electrical systems.
- Commercial and infrastructure power distribution.
- Fixed low-voltage switchgear assemblies.
