ME024FSD024 Lovato ELECTR. DOL STARTER WITH STO 24VDC 2.4A

Why Choose the Lovato ME024FSD024 Electronic Direct-On-Line Starter?

The Lovato ME024FSD024 is a compact electronic direct-on-line (DOL) motor starter designed for reliable switching, thermal motor protection and safety-related stopping in industrial machinery and automation systems. As part of the Lovato ME electronic motor starter series, it combines electronic motor control with integrated protection and Safe Torque Off (STO) functionality in a space-saving DIN rail format.

This electronic starter has a rated operational current of 2.4 A for AC-3 and AC-53a duties and provides integrated Class 10A thermal protection with an adjustable trip range of 0.18–2.4 A. Its built-in STO safety function is rated up to SIL 3 according to IEC 61508 and PL e according to ISO 13849-1, supporting integration into machinery safety systems.

With an operational voltage range of 40–500 V AC, rated frequency of 50/60 Hz and a 24 V DC auxiliary and control supply, the ME024FSD024 provides a versatile solution for three-phase motor applications. Its slim 22.5 mm width and 35 mm DIN rail mounting help reduce panel space requirements while its hybrid electronic design supports applications with frequent switching cycles.
