1SAZ721201R1021 TF42-0.74, ABB TF42 Thermal Overload Relay 1NO + 1NC, 0.55 → 0.74 A F.L.C, 740 mA Contact Rating, 2 W, 3P, AF Range, Реле

ABB Thermal Overload Relay, 45mm Width, -25°C to +60°C Operating Temperature Range - TF42 Series - TF42-0.74

To keep your machinery safe from electrical hazards, shield it with this thermal overload relay from ABB. The unit has a 3-pole configuration, so you can use it with 3-phase systems or protect multiple circuits. A phase-loss sensitivity function causes it to trip if any phase is lost, which averts potential damage and prevents unsafe operation. As the relay has a compact size of 88.3 (H) x 45 (W) x 70.5mm (D), it takes up little space in your enclosure. For improved security, you can seal the operating elements of this component to prevent accidental or unauthorised adjustments to its settings.
