ABB 1SDA066758R1 Moulded Case Circuit Breaker - TMF IEC

Feature Front-terminal connection and 4P design: With front terminal access and four poles, installation is faster and wiring runs remain organized, reducing commissioning time and error. This translates into lower labour costs and quicker service responses in dense electrical panels, especially in retrofit projects or new line builds. Feature TMF release and TM release type: Provides reliable tripping under TMF conditions, enabling safer shutdowns and better selectivity in complex power networks. Application Ideal for industrial control panels, machine feeders, and transformer protection where space is limited and reliability is critical. Feature Rated current and voltage: Main circuit rated at 20 A with rated insulation voltage of 690 V and rated operational voltage of 550 V AC / 250 V DC, supporting diverse industrial networks while maintaining safety margins. Feature Short-circuit capacity: Ics up to 50 kA and Icu up to 100 kA (depending on voltage), delivering robust protection for high-energy applications and reducing risk of equipment damage. Feature Durability and lifecycle: Electrical durability of 1500 cycles and mechanical durability of 8500 cycles, ensuring long service life in high-switching environments and minimizing maintenance costs. Feature Compliance and packaging: RoHS, REACH and TSCA declarations accompany packaging disposal information, helping ensure regulatory alignment and streamlined procurement for global operations.
