The ABB 1SDA124837R1 is a high-performance low-voltage air circuit breaker (ACB) designed for reliable protection and switching in demanding electrical distribution systems. As part of the advanced ABB SACE Emax 3 E2.3N series, it combines robust circuit protection with intelligent Ekip Aware electronic release technology for modern power distribution applications.
This circuit breaker features a 1600 A rated current, three-pole fixed configuration and LI protection functions for overload and short-circuit protection. Its rear horizontal terminals provide a practical connection arrangement for installation within low-voltage switchboards and electrical distribution assemblies.
The E2.3N 1600 Ekip Aware LI configuration provides a 66 kA rated short-circuit breaking capacity at 400 V AC, supporting reliable protection in high-current industrial and commercial electrical systems. The breaker also includes four auxiliary contacts and an open/closed circuit-breaker position indication.
Air circuit breakers such as the ABB Emax 3 E2.3N provide dependable protection and switching for high-current low-voltage electrical distribution systems. The electronic Ekip Aware release continuously manages the configured protection functions, helping protect conductors and connected equipment against damaging overload and short-circuit conditions.
The fixed three-pole construction and rear horizontal terminal arrangement make the 1SDA124837R1 suitable for integration into switchboards, distribution panels and industrial power systems. Its Ekip Aware architecture also supports the monitoring and intelligent management capabilities associated with the Emax 3 platform.
