Why Choose the ABB 1SDA074634R1 XT1N 125 TMF 15-500 3-Pole Circuit Breaker?
The ABB 1SDA074634R1, designated XT1N 125 TMF 15-500 3p F F UL/CSA, is a fixed three-pole moulded case circuit breaker (MCCB) from the ABB SACE Tmax XT range. Built on the compact XT1N 125 frame, it has a rated current of 15 A and a TMF thermal-magnetic release for dependable overload and short-circuit protection.
Designed for UL/CSA applications, this XT1N breaker is rated for 600Y/347 V AC systems and carries an N interruption rating of 25 kA at 480 V AC. The TMF release combines fixed thermal overload protection at 15 A with an instantaneous magnetic short-circuit threshold of 500 A.
The 1SDA074634R1 is supplied as a fixed breaker with front terminals and a three-pole configuration. Its compact dimensions, approximately 76.2 × 130 × 70 mm, make it well suited to industrial machinery, control panels and commercial distribution equipment where space-efficient UL-certified circuit protection is required.

Compact Thermal-Magnetic Protection for UL/CSA Applications
The TMF trip unit uses thermal and magnetic operating principles to protect electrical circuits without requiring an external power supply. The thermal element responds to sustained overload conditions, while the magnetic element provides rapid tripping when a severe short-circuit current reaches the specified instantaneous threshold.
For the ABB 1SDA074634R1, the thermal protection is rated at 15 A and the instantaneous magnetic threshold is 500 A. Combined with the XT1N interruption rating of 25 kA at 480 V AC, this provides a compact protection solution for compatible North American power distribution and equipment applications.
Typical Applications
- Industrial control panels and machinery.
- Commercial low-voltage distribution systems.
- Three-phase feeder and branch circuits.
- OEM electrical equipment and panel assemblies.
- Motor and equipment distribution circuits requiring upstream protection.
- UL/CSA-oriented switchboards and electrical enclosures.
- Applications requiring compact 15 A thermal-magnetic protection.
