Why Choose the ABB XT3N 250 TMD 1SDA070164R1 Circuit Breaker?
The ABB XT3N 250 TMD 1SDA070164R1 is a four-pole moulded case circuit breaker (MCCB) designed for dependable protection of low-voltage electrical distribution systems. Part of the ABB SACE Tmax XT3 range, it combines a 250 A frame with a 63 A TMD thermomagnetic trip unit for overload and short-circuit protection.
This XT3N circuit breaker is supplied in a fixed configuration with front terminals. Its TMD release has a rated current of 63 A, an adjustable thermal overload setting down to 44.1 A and an instantaneous magnetic short-circuit setting of 630 A, providing straightforward circuit protection without requiring an electronic trip unit.
The XT3N performance level provides a rated ultimate short-circuit breaking capacity of 36 kA at 400 V AC. Designed for operation with the trip unit calibrated at 50 °C, the 1SDA070164R1 is suitable for industrial, commercial and OEM distribution systems requiring a compact four-pole thermomagnetic MCCB.

Thermomagnetic Protection for Power Distribution
The TMD release combines two established protection principles in a single trip unit. The thermal element responds to sustained overload conditions, while the magnetic element provides rapid operation during high short-circuit currents. On the 1SDA070164R1, the thermal overload setting can be adjusted between 44.1 A and 63 A, while the instantaneous short-circuit release is set at 630 A.
This thermomagnetic arrangement provides robust circuit protection without the configuration requirements of an electronic release. Combined with the XT3N frame's 36 kA breaking capacity at 400 V AC, four-pole construction and fixed front-connected design, it makes the breaker well suited to conventional low-voltage distribution and panel-building applications.
Typical Applications
- Industrial low-voltage power distribution systems.
- Commercial building distribution switchboards.
- Three-phase and neutral feeder protection.
- Electrical control and distribution panels.
- Industrial machinery and equipment supplies.
- OEM switchgear and panel-building applications.
