Why Choose the ABB MA 200-2800 T4 3-Pole Magnetic Release?
The ABB 1SDA054680R1 is an MA 200-2800 three-pole magnetic release designed for use with ABB SACE Tmax T4 moulded-case circuit breakers. Part of the ABB SACE Tmax T family, it provides instantaneous short-circuit protection for circuits and loads where overload protection is provided separately.
The MA release uses an adjustable magnetic trip mechanism to respond rapidly to high fault currents. This version has a reference current of 200 A and an adjustable instantaneous magnetic trip threshold of 1400–2800 A, allowing the protection setting to be coordinated with the starting and fault-current characteristics of the connected equipment.
Designed for three-pole ABB Tmax T4 circuit breakers, the MA 200-2800 is particularly suitable for motor protection applications used together with a separate overload protection device. Its magnetic-only operation provides fast short-circuit protection while avoiding the thermal overload function found in TMA thermomagnetic releases.
Key Advantages
- Dedicated instantaneous magnetic short-circuit protection.
- 200 A reference current for compatible Tmax T4 applications.
- Adjustable 1400–2800 A magnetic trip threshold.
- Three-pole configuration for three-phase circuits.
- Ideal for motor circuits where overload protection is provided separately.
- Designed specifically for ABB SACE Tmax T4 moulded-case circuit breakers.
Key Features
- ABB MA magnetic release.
- 200 A reference current.
- 1400–2800 A adjustable instantaneous magnetic trip range.
- Designed for ABB SACE Tmax T4 circuit breakers.
- 3-pole configuration.
- Magnetic-only protection against short-circuit currents.
- Suitable for coordinated motor protection arrangements.
- Electromechanical protection without an electronic trip unit.
Fast Magnetic Protection for Motor Circuits
Magnetic-only releases are designed to trip rapidly when current rises to a level associated with a short circuit. Unlike thermomagnetic releases, an MA release does not provide thermal overload protection, allowing it to be combined with a dedicated motor overload device in a coordinated protection system.
The adjustable 1400–2800 A instantaneous trip range allows the ABB MA 200-2800 to accommodate high motor starting currents while still providing rapid protection against damaging short-circuit faults. This makes it a practical solution for industrial motor feeders and other applications requiring magnetic-only circuit-breaker protection.
Typical Applications
- Industrial motor feeders and motor control systems.
- ABB SACE Tmax T4 moulded-case circuit breakers.
- Three-phase industrial machinery.
- Motor control centres and electrical switchboards.
- Circuits with separate thermal overload protection.
- Industrial installations requiring instantaneous short-circuit protection.
