1SDA074912R1 ABB XT2S 125 Ekip LS/I 60A 3-Pole UL/CSA Circuit Breaker

Why Choose the ABB 1SDA074912R1 XT2S 125 Ekip LS/I 60A 3-Pole Circuit Breaker?

The ABB 1SDA074912R1, designated XT2S 125 Ekip LS/I In=60A 3p F F UL/CSA, is a fixed three-pole moulded case circuit breaker (MCCB) from the ABB SACE Tmax XT range. Built on the XT2S 125 frame, it has a rated current of 60 A and uses an Ekip Dip LS/I solid-state electronic trip unit for precise overload and short-circuit protection.

The Ekip LS/I release provides long-time overload (L), short-time short-circuit (S) and instantaneous short-circuit (I) protection. Electronic protection offers accurate and repeatable tripping characteristics, supporting effective coordination within industrial, commercial and OEM low-voltage distribution systems.

Designed for UL/CSA applications, the 1SDA074912R1 is supplied as a fixed three-pole breaker with front terminals. The XT2S performance level provides a UL interruption rating of 35 kA at 480 V AC, while ABB specifies a rated voltage of 600 V for this configuration.

Key Advantages

Electronic LS/I Protection for Coordinated Distribution Systems

The Ekip Dip LS/I release uses electronic current measurement to provide precise protection against the principal overcurrent conditions encountered in low-voltage distribution systems. Long-time protection responds to sustained overloads, short-time protection enables controlled response to short-circuit currents, and instantaneous protection provides rapid interruption of severe faults.

For the ABB 1SDA074912R1, these electronic protection functions are combined with a 60 A rated current and the XT2S interruption performance of 35 kA at 480 V AC. This makes the breaker suitable for applications requiring more sophisticated protection and coordination than a conventional fixed thermal-magnetic release can provide.

Typical Applications

• Industrial low-voltage distribution panels.
• Commercial building electrical distribution systems.
• Three-phase feeder and branch circuits.
• OEM machinery and electrical equipment.
• Control panels and power distribution enclosures.
• Distribution circuits requiring electronic LS/I protection.
• UL/CSA-oriented switchboards and electrical assemblies.
