LZ8H2X4BD
Reversing ultra compact starter, TeSys Hybrid, Safe Torque Off, 3P, 500VAC, 0.75kW at 400V, 24VDC

TeSys H ultra compact reverse safety starter, 3 poles, 2.4A/500V AC-53, for control and protection of 3-phase motors up to 0.75kW@400V (1HP@480V). The hybrid technology used for power contacts procures ultra compactness (22.5mm width) as well as an extended electrical durability up to 30 million cycles AC-53. It provides control for 2 directions of rotation, an adjustable motor current 0.18-2.4A, class 10A thermal overload protection with auto/manual/remote reset, phase loss and phase unbalanced protection, stall and jam motor protection. To be supplied with 24V DC, it provides logic inputs for FW/RV motor direction and remote reset after thermal tripping, 1C/O contact relay for fault indication, LED status on front face for indication of tripping and motor running. With an integrated Safe Torq Off (STO) function with SIL3 level according IEC61508-1 and PLe level according ISO13849-1, it can be integrated to safety chain applications. DIN rail mounting, screw terminals for control and power, it can be used without derating for ambient temperatures from -25 to 70°C. Multi standards certified (IEC, UL, CCC), Green Premium compliant (RoHS/REACh).
