Electronic motor protection relays Classic Range Mx325

Electronic motor protection relays Classic Range Mx325 are intelligent devices designed to safeguard three-phase induction motors against overloads, phase unbalance, phase loss, and short circuits. These relays typically feature adjustable current settings (e.g., 0.3-1.5A, 1.5-6A, 6-25A ranges), thermal memory for accurate motor heating modeling, and selectable trip classes (Class 10, 20, or 30) to match motor starting characteristics. They support both direct and remote reset modes, with LED indication for status and fault diagnosis. The Classic Range Mx325 series offers compact DIN-rail mounting for easy integration into control panels, with auxiliary contacts (1 NO + 1 NC) for alarm and trip signaling.

These relays are primarily deployed in motor control centers (MCCs), industrial automation panels, and pumping stations for protecting motors driving conveyors, compressors, fans, and pumps. They are essential in sectors such as water treatment, HVAC, manufacturing, and mining, where continuous motor operation is critical. The devices can be wired in series with contactors and circuit breakers to form a complete motor protection scheme, ensuring compliance with IEC 60947-4-1 standards.

The Classic Range Mx325 series includes subcategories based on current range and supply voltage. Key article codes include Mx325-0.3-1.5 (0.3-1.5A range), Mx325-1.5-6 (1.5-6A), Mx325-6-25 (6-25A), and Mx325-25-100 (25-100A). The code structure typically follows the pattern Mx325-[current range], where the current range indicates the adjustable trip setting window. These are the main protection units, not accessories like remote reset modules or communication adapters.
