ABB 1SDA066732R1 MCB - TMF 125-1250 A, IEC
Part Number: 1SDA066732R1
Quick Summary
ABB 1SDA066732R1 MCB protects industrial control panels with reliable molded case-breaker protection for power distribution. Engineers often contend with nuisance trips and limited short-circuit withstand in compact enclosures, which can drive downtime. This device aligns with IEC standards and CE conformity, with RoHS and REACH declarations ensuring compliant sourcing. Designed for front-terminal, three-pole protection, it reduces wiring time and maintenance costs in automation projects. In addition, predictable operation under fault conditions and measured power loss of 11 W per pole support energy-efficient, low-drag panel design.
