ABB 1SDA116228R1 Moulded Case Circuit Breaker - TMD

Three-pole front-terminal design simplifies wiring and reduces enclosure footprint, enabling faster commissioning and fewer wiring errors in panel boards and switchgear. The business impact is clear: quicker deployment on the shop floor and lower installation labor costs. This is ideal in space-constrained electrical rooms and new-builds where reliability matters. The TMD thermal-magnetic release provides precise protection coordination, minimizing nuisance trips while preserving downstream equipment and production uptime in high-demand manufacturing lines. In practice, that means safer starts and reduced maintenance interventions, especially in mixed-voltage environments where both AC and DC supplies are present. The setting range of 14–20 A lets you tailor protection to branch circuits, improving selective tripping and reducing unnecessary outages in production lines. For installers, the front-terminal design underpins straightforward wiring and robust mechanical integrity during service and retrofit projects. The device’s 20 A nominal current rating aligns with typical distribution circuits, while its 500 V AC / 250 V DC insulation voltage supports mixed-use panels found in modern facilities. RoHS and REACH declarations, together with CMRT and TSCA disclosures, simplify regulatory compliance across global sites. The rugged mechanical durability—up to 20000 cycles—translates into longer service intervals and lower lifecycle costs, which is especially valuable in high-vibration environments and maintenance-heavy industries. In ABB’s SACE FORMULA DSP family, this MCCB complements other protection devices for coherent, reliable power distribution protection strategies.
