Front-terminal, four-pole design with a 25 A rating enables rapid wiring and safer maintenance, reducing panel assembly time while providing synchronized protection for multi-phase feeders in industrial control cabinets. The TMF thermomagnetic release delivers fast opening during short circuits and stable operation during overloads, enhancing selective coordination in power distribution for transformer feeders and motor circuits. With 690 V rated insulation and 550 V AC / 250 V DC operational voltages, it supports robust protection across common industrial voltages, reducing nuisance trips and improving uptime. Electrical durability rated at 1500 cycles and mechanical durability at 8500 cycles indicate long service life in challenging environments, while 3 W per pole power loss supports lower operating costs. The compact footprint (101.6 mm wide, 130 mm high, 60 mm deep) and front-connection terminals simplify installation in standard enclosures, aiding retrofit projects and OEM builds. Comprehensive documentation including Data Sheet 1SDC210032D0204, wiring diagrams FORMULA A1-A2, and RoHS/REACH declarations support fast approvals and maintenance planning.
