Why Choose the ABB XT5N 400 MA 1SDA100365R1 Circuit Breaker?
The ABB 1SDA100365R1 is a high-performance SACE Tmax XT5N moulded-case circuit breaker (MCCB) designed for motor protection and reliable switching in low-voltage electrical systems. This fixed three-pole circuit breaker features front terminals and an MA magnetic trip unit, providing adjustable instantaneous short-circuit protection for industrial motor circuits.
As part of the advanced ABB SACE Tmax XT series, the XT5N 400 combines compact construction with dependable circuit protection. The MA release is specifically suited to motor protection applications where overload protection is provided separately, while the circuit breaker delivers adjustable instantaneous magnetic protection against high fault currents.
With a rated current of 400 A and an adjustable instantaneous magnetic trip range of 2800–5200 A, the XT5N 400 MA is suitable for demanding motor and industrial power applications. The N breaking-capacity version provides an ultimate short-circuit breaking capacity of 36 kA at 400–415 V AC, while its fixed mounting and front-terminal configuration simplify integration into electrical panels and switchboards.

Reliable Short-Circuit Protection for Industrial Motors
Motor circuits require effective protection against high short-circuit currents while allowing the high starting currents associated with electric motors. The ABB XT5N 400 MA uses an adjustable magnetic release to provide rapid interruption when current exceeds the selected instantaneous protection threshold.
The adjustable 2800–5200 A magnetic setting enables the protection characteristics to be coordinated with the motor and installation. Because the MA release provides magnetic short-circuit protection rather than conventional thermal overload protection, appropriate separate motor overload protection should be incorporated into the overall motor control and protection system.
Typical Applications
- Industrial motor protection systems.
- Motor control centres and electrical control panels.
- Pumps, fans and compressor installations.
- Conveyors and material handling equipment.
- Manufacturing and process machinery.
- Industrial switchboards and power distribution systems.
