Professional 3-pole motor contactor with 32A AC-3 rating, 24V DC actuation, 2NO+2NC auxiliary contacts, and 12 million mechanical operations endurance for industrial switching applications.
The Legrand CTX³ motor contactor is a professional-grade electrical switching device designed for industrial and tertiary installations. This 3-pole contactor features a 32A AC-3 rating, making it suitable for switching 3-phase motors up to 15 kW at 415V, with additional capacity for resistive loads up to 50A AC-1. The contactor is equipped with 24V DC actuation and includes 2 normally open (NO) and 2 normally closed (NC) auxiliary contacts, with the NC contact meeting the mirror contact definition according to IEC 60947-4-1 standards.
Designed for reliability and durability, this CTX³ contactor offers exceptional endurance with up to 12 million mechanical operations and 2 million electrical operations, supporting 1800 operation cycles per hour under AC-3 conditions. The device features screw terminal connections with power capacity from 2 x 1.5mm² to 10mm² and coil connections from 0.75mm² to 2.5mm². The compact design allows for mounting on 35mm DIN rails or mounting plates, optimizing cabinet space while maintaining full functionality.
The CTX³ contactor incorporates advanced engineering features including a removable front cover for visual inspection of arc chambers and contacts, and the innovative capability to supply the coil from either the top or bottom side. Compatible with all Legrand CTX3 auxiliaries and accessories, this contactor is fully compliant with substance-restriction requirements and designed through environmentally conscious manufacturing processes.
