ABB 1SDA100698R1 TMG 630-3150 is a 630 A four-pole thermomagnetic generator-protection trip unit for Tmax XT5 circuit breakers with adjustable 1575–3150 A magnetic protection and a 100% rated neutral.
£540.69
The ABB 1SDA100698R1 is a TMG thermomagnetic trip unit designed specifically for generator protection with ABB Tmax XT5 moulded-case circuit breakers. Rated at 630 A, it combines thermal overload protection with adjustable magnetic short-circuit protection for dependable protection of low-voltage generating sets and associated distribution circuits.
As part of the ABB Tmax XT generator protection range, the TMG release uses proven thermomagnetic technology that does not depend on electronic trip-unit circuitry. The thermal element responds to sustained overload conditions, while the magnetic element provides rapid protection against high short-circuit currents, making the release particularly suitable for generator applications.
The TMG 630-3150 XT5 4p In=100%In is configured for a four-pole XT5 circuit breaker with full-rated neutral protection. Its phase and neutral rated current is 630 A, while the magnetic short-circuit protection is adjustable from 1575–3150 A, allowing the protection characteristics to be coordinated with generator operating requirements.
Generator circuits require protection characteristics suited to the fault-current behaviour and operating conditions of generating sets. The ABB TMG range combines thermal overload protection with adjustable magnetic short-circuit protection, allowing the circuit breaker to protect the generator while accommodating normal operating currents.
When combined with a compatible ABB Tmax XT5 breaking part, the 1SDA100698R1 provides a robust four-pole generator protection solution. Its full-rated neutral pole is particularly useful where the neutral conductor must carry and be protected at the same rated current as the phase conductors.
