The ABB TMA 500-5000 XT5 4p InN=50%In, order code 1SDA100653R1, is a four-pole thermomagnetic trip unit designed for use with compatible ABB SACE Tmax XT5 moulded case circuit breaker breaking parts. Rated at 500 A, it provides reliable overload and instantaneous short-circuit protection for AC and DC low-voltage power distribution applications.
As part of the ABB Tmax XT5 TMA range, this trip unit combines thermal overload protection with adjustable magnetic short-circuit protection. Its instantaneous magnetic protection setting can be adjusted from 2500–5000 A, allowing the protection characteristics to be configured for the requirements of the electrical distribution system.
The four-pole 1SDA100653R1 incorporates neutral protection rated at 50% of the phase setting. Designed to operate with a compatible XT5 breaking part, the TMA release provides a straightforward thermomagnetic protection solution for switchboards, distribution panels and industrial power systems where dependable circuit protection without a complex electronic trip unit is required.
Thermomagnetic trip units combine two complementary protection principles within a circuit breaker. The thermal element responds to sustained overload currents using an inverse-time characteristic, while the magnetic element operates rapidly when a high short-circuit current exceeds the configured instantaneous threshold.
The ABB TMA 500-5000 provides this protection in a robust four-pole format for the Tmax XT5 platform. Its adjustable 2500–5000 A magnetic threshold allows short-circuit protection to be coordinated with the installation, while the 50% neutral setting provides dedicated neutral protection for suitable four-wire distribution systems.

The ABB 1SDA100653R1 is a TMA thermomagnetic trip unit designed for use with compatible ABB SACE Tmax XT5 moulded case circuit breaker breaking parts to provide overload and short-circuit protection.
The trip unit has a rated current of 500 A and uses a four-pole configuration.
The instantaneous magnetic short-circuit protection can be adjusted from 2500–5000 A, equivalent to approximately 5–10 × In.
InN=50%In means that the neutral pole protection is set at 50% of the phase rated-current setting, providing dedicated neutral protection in the four-pole circuit-breaker configuration.
The 1SDA100653R1 is designed for use with a compatible ABB SACE Tmax XT5 breaking part and must be combined with the appropriate breaking unit to form a complete circuit breaker.
ABB TMA thermomagnetic trip units provide robust overload and short-circuit protection within the SACE Tmax XT platform, offering straightforward adjustable protection for industrial, commercial and infrastructure low-voltage distribution systems.
