Why Choose the ABB XT3N 250 TMD 1SDA070165R1 Circuit Breaker?
The ABB XT3N 250 TMD 1SDA070165R1 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 an 80 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 80 A, with adjustable thermal overload protection from 56–80 A and an instantaneous magnetic short-circuit release set at 800 A. This provides straightforward and robust protection without requiring an electronic trip unit.
The XT3N performance level provides a rated ultimate short-circuit breaking capacity of 36 kA at 400 / 415 V AC. With a thermomagnetic release calibrated at 50 °C, four-pole construction and a fixed front-connected design, the 1SDA070165R1 is well suited to industrial, commercial and OEM power distribution applications.

Thermomagnetic Protection for Power Distribution
The TMD release combines thermal and magnetic protection within a mechanically straightforward trip unit. The thermal element responds to sustained overload conditions and can be adjusted from 56–80 A, allowing the protection level to be matched to the connected circuit. The magnetic element provides rapid operation during severe short-circuit conditions, with an instantaneous release setting of 800 A.
Combined with the XT3N frame's 36 kA short-circuit breaking capacity at 400 / 415 V AC, this thermomagnetic protection makes the 1SDA070165R1 a practical solution for conventional low-voltage distribution. Its four-pole construction supports three-phase and neutral applications, while fixed mounting and front connections simplify integration into compatible switchboards and control panels.
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.
