CNM3210220 - MODULAR CONTACTOR CN32 220/230VAC MANUAL

Why Choose the CNM3210220?

Designed for dependable switching in building and industrial panels, the Lovato CNM3210220 is a modular contactor with manual control offering a four-pole 4NO configuration and 32 A AC-1 capability. This compact, two-module DIN width device provides clear, hands-on operation for maintenance or override needs while maintaining robust performance. It’s an ideal choice where reliable, standards-compliant control is required across lighting and other resistive load applications.

Built to last, the CNM contactor delivers a mechanical life of 3,000,000 cycles and withstands transients with a 4 kV Uimp and 440 V Ui. Rated supply is 220VAC/VDC, with IP20 frontal protection and pollution degree 3. Operates from -25 to +70 °C, stores -30 to 80 °C, and is specified to 2000 m altitude, meeting IEC/EN 60947 and 61095 requirements.
