Feature → Business Impact → Application: Four‑pole, front‑terminal construction provides clean, accessible wiring and reduces installation time, while a 20 A rated current and 600 V rating deliver reliable protection for moderate power distribution in industrial facilities. This translates to less nuisance trips and lower risk of arc faults in panels, especially where motor loads or transformers are present. Application: ideal for SACE Tmax XT installations in control cabinets and switchgear where compact footprint and front‑access terminals save space and simplify commissioning. Feature → Business Impact → Application: TMF (thermal magnetic) release delivers fast, reliable tripping with a typical opening time around 30 ms, minimizing fault energy and protecting downstream equipment. Application: suitable for critical feeders and transformer protections in distribution systems. Feature → Business Impact → Application: 4P configuration and front terminal connection support easy busbar integration and modular partitioning, enabling scalable panel design and reduced wiring complexity. Application: panel builders seeking repeatable, code‑compliant protection blocks. Feature → Business Impact → Application: Compliance with UL489, CSA, and CE declarations reduces engineering overhead and accelerates approvals for multinational deployments. Application: multinational plants requiring harmonized protection standards. Feature → Business Impact → Application: EcoSolutions and recyclability data promote sustainable design choices, aiding in cradle‑to‑grave planning and end‑of‑life handling. Application: long‑term sustainability programs in manufacturing environments. Feature → Business Impact → Application: 4P, front‑terminal, 32.5–100 mm² busbar compatibility and M6 screw‑driver guidance streamline installation and maintenance. Application: technicians performing field replacements or upgrades in existing switchboards.

FAQs
The ABB 1SDA074804R1 is designed for SACE Tmax XT low‑voltage applications and fits standard distribution panels that require four‑pole front‑terminal circuit breakers. It supports UL489/CSA requirements and CE declarations, making it suitable for multinational installations. When planning a retrofit, verify busbar size (32.5–100 mm²) and front‑terminal accessibility to ensure a clean field integration with existing switchgear.
This MCCB is rated at 20 A with a rated operational voltage of 600 V and a rated uninterrupted current of 125 A. It provides an instantaneous short‑circuit setting of 400 A and a breaking capacity specified under UL489/CSA. The device uses a front‑mounted 4P configuration, with a recommended screwdriver size of M6 for main circuit connections and a tightening torque of 6 N·m.
Yes. The unit is listed under UL489 and CSA standards, with accompanying CSA and UL certificates referenced in the datasheet. It also carries a CE declaration of conformity, enabling use in European electrical installations. This combination supports cross‑border procurement and simplifies compliance workflows for manufacturers operating in multiple regions.
Designed for durability and repeatability, the 1SDA074804R1 offers 8,000 electrical cycles and up to 25,000 mechanical cycles, reducing replacement frequency and unplanned downtime. Front‑terminal access simplifies wiring checks and field servicing, while TMF protection ensures fast, predictable trips, helping maintenance teams isolate faults quickly and restore service with minimal disruption.
Plan for a front‑access installation with busbars in the 32.5–100 mm² range and ensure adequate panel space for the 120 mm × 130 mm footprint and 1.45 kg weight. Use the recommended M6 screwdriver and torque of 6 N·m for secure terminal connections. Verify clearance for front terminals and maintain proper wiring routing to prevent interference with neighboring devices.
