Why Choose the ABB XT2H 125 MCP Iu=80 1SDA074888R1 Circuit Breaker?
The ABB 1SDA074888R1 is a high-performance three-pole motor protection circuit breaker (MCP) designed to provide magnetic short-circuit protection for motor circuits in low-voltage industrial electrical systems. As part of the ABB SACE Tmax XT / T-Max XT 250 range, this XT2H 125 breaker combines compact construction with high interruption capability for demanding motor control and machinery applications.
This circuit breaker incorporates an ABB MCP magnetic-only trip unit with an adjustable instantaneous trip range. Unlike a conventional thermomagnetic circuit breaker, the MCP release is specifically intended for magnetic short-circuit protection and is typically coordinated with separate motor overload protection as part of a complete motor branch circuit.
With a rated current of 80 A, an adjustable instantaneous magnetic release range of 240–880 A and a rated voltage of 600 V AC, the XT2H 125 MCP provides robust protection for three-phase motor circuits. The H breaking-capacity version provides an interruption rating of 65 kA at 480 V AC, while its fixed three-pole construction and front terminals simplify integration into motor control panels and switchboards.

Reliable Short-Circuit Protection for Motor Circuits
Motor protection circuit breakers such as the ABB XT2H 125 MCP are designed to provide rapid magnetic protection against high short-circuit currents in motor branch circuits. The adjustable instantaneous magnetic release allows the protection threshold to be coordinated with motor starting current while providing fast disconnection when a severe fault occurs.
Because the MCP trip unit provides magnetic rather than thermal overload protection, the 1SDA074888R1 is intended to form part of a coordinated motor protection system incorporating appropriate overload protection. Its compact XT2 frame, high interruption capability, fixed mounting arrangement and front terminals make it particularly suitable for motor control centres, industrial machinery and OEM control panels.
Typical Applications
- Industrial motor control centres.
- Three-phase motor branch circuits.
- Industrial machinery and production equipment.
- Pumps, fans and compressor systems.
- Conveyors and material handling equipment.
- Electrical switchboards and motor control panels.
- OEM machinery and automation systems.
