1. Overview of ABB 1SDA055914R1
ABB Emax 2 E2N 1600 Air Circuit Breaker
The ABB 1SDA055914R1 is a 4 pole withdrawable air circuit breaker
in the Emax 2 series with a frame current of 1600 A. It integrates
the PR121/P-LSIG full-function electronic trip unit and is designed
for main and feeder protection in 380 V–690 V low-voltage
distribution and industrial systems. Its high 65 kA breaking
capacity and 100% Ics operating breaking capacity ensure rapid and
reliable interruption of fault currents in the event of
short-circuit faults, ensuring system safety and continuous
operation.
2. Core Advantages:
High interrupting capacity: Icu = 65 kA @ 415 V AC, Ics = 100% Icu.
Full-function protection: Four-stage protection: overload,
short-time delay, instantaneous, and ground fault, precisely
adjustable.
Withdrawable design: Quickly replaceable while energized, ensuring
zero maintenance downtime.
Intelligent communications: Standard Modbus RTU, with optional
Profibus and Ethernet gateways.
Wide operating temperature range: -25°C to +70°C, suitable for
harsh industrial environments.
