ABB 1SDA065451R1 Moulded Case Circuit Breaker - UL/CSA

Front-terminal two-pole design with TMF thermal-magnetic release is engineered for straightforward wiring and reliable fault clearance. This arrangement reduces wiring errors and commissioning time, delivering faster panel builds and safer maintenance in high-density switchgear. It is ideal for motor starters, distribution boards, and control panels where space is at a premium and accessibility matters. Two-pole construction with a TMF release covers 25 to 500 A, enabling precise coordination within SACE Tmax protection schemes. The circuit breaker trips quickly on overloads and short circuits, helping keep critical loads protected with minimal downtime. This supports energy efficiency programs by minimizing unnecessary disconnections and facilitating selective tripping. UL/CSA recognition and CE conformity, backed by installation instructions Ts3, ensure compliant procurement and reduced risk during field deployment. Designed for seamless integration with the SACE Tmax family, it standardizes panel protection across multiple OEMs and projects. With a compact footprint (105 mm width, 170 mm height, 103.5 mm depth) and a weight of 1.6 kg, it fits common enclosure layouts while enabling straightforward retrofits. Documentation, including the Tmax data sheet and installation guides, accelerates commissioning and reduces training requirements for maintenance teams. In practice, this means lower total cost of ownership, fewer miswired connections, and a faster path to compliant, reliable protection across critical electrical networks.
