Why Choose the ABB MA 400-4000 XT5 3p Trip Unit?
The ABB 1SDA100615R1 is an MA magnetic trip unit designed for motor protection applications with three-pole ABB SACE Tmax XT5 moulded case circuit breakers. With a rated current of 400 A, it provides adjustable instantaneous magnetic short-circuit protection for motors and associated electrical circuits in demanding industrial installations.
As part of the ABB SACE Tmax XT5 range, the MA release is intended for applications where motor overload protection is provided separately and the circuit breaker is required to provide rapid protection against short-circuit faults. Its adjustable magnetic threshold helps accommodate normal motor starting currents while maintaining effective fault protection.
The 1SDA100615R1 is a three-pole AC/DC magnetic protection release with a rated current of 400 A. Its instantaneous short-circuit setting is adjustable from 2800–5200 A, corresponding to 7–13 × In, and the unit is supplied in a loose or configurable format for association with a compatible three-pole XT5 breaking part.

Reliable Magnetic Protection for Motor Circuits
Motor circuits can draw substantial inrush current during starting, so their short-circuit protection must accommodate normal starting conditions while responding rapidly to damaging fault currents. The ABB MA release provides adjustable instantaneous magnetic protection, allowing the operating threshold to be coordinated with motor characteristics and the requirements of the electrical installation.
The MA 400 release is particularly suited to motor applications where overload protection is provided by a separate overload relay or coordinated motor protection device. When combined with a compatible three-pole XT5 breaking part, the 1SDA100615R1 provides a flexible short-circuit protection solution for industrial motors, machinery and other high-current motor loads.
Typical Applications
- Industrial three-phase motor protection.
- Motor control centres and distribution panels.
- Pumps, fans and ventilation systems.
- Compressors and refrigeration machinery.
- Conveyors and material handling equipment.
- Industrial production and processing machinery.
- Motor circuits using separate overload protection.
