AC-51 is the least demanding duty class; for motor or transformer loads you derate significantly. The UL 508 listing at 45 A tells you the part is accepted for US panel builds. Minimum operational current is 500 mA — below that the thyristor may not latch cleanly. The I²t value of 6600 A²·s is the fuse coordination number: pair with the recommended NEOZED fuse 5SE2335 for semiconductor protection. Side-by-side mounting is permitted — no mandatory spacing gap, which saves rail space. Dimensions: 67 mm wide, 100 mm tall, 141 mm deep. Main circuit uses screw-type terminals accepting 1.5...6 mm² solid or stranded; control circuit terminals accept 1x 0.5...2.5 mm² or 2x 0.5...1.0 mm² solid. Pollution degree 3 (conductive pollution, typical for industrial control panels). Rated insulation voltage 600 V.","metaTitle":"Siemens 3RF2350-1AA02 SIRIUS solid-state contactor, 50 A AC-","metaDescription":"Siemens 3RF2350-1AA02 SIRIUS single-phase solid-state contactor, 50 A AC-51, 24-230 V AC control, zero-point switching, DIN-rail mount.
