Hager Contactor 40A 3NO 230V ESC340

Hager ESC340: 40A 3-Pole Contactor with 3NO contacts, rated for 230V~50Hz control voltage and built for remote switching of power circuits in distribution board installations.

Reliable Power Switching & Control

The ESC340 handles AC1 loads up to 40A across three normally open poles, giving you dependable remote switching for lighting, heating, and general power circuits. A 230V excitation voltage keeps control wiring straightforward on standard supplies, and the contactor accepts the ESC080 auxiliary contact if you need additional switching signals for interlocking or indication.

Flexible Configuration for Every Load

Rated for up to 4000W of incandescent lighting or 1900VA of fluorescent load (rising to 3000VA on duo circuits and 1300VA when parallel compensated), this Hager contactor covers a wide spread of lighting control applications without needing a larger frame. Since all ratings apply to AC1 loads only, check your load type against the datasheet and de-rate where necessary for other categories.

Installation & Compliance

Occupying just 3 modular spacings on the DIN rail, the ESC340 fits neatly alongside other Hager distribution board components without eating into panel space. An IP2X rating protects against accidental finger contact once installed behind a distribution board front, and Hager recommends fitting LZ060 heat dissipation inserts between contactors, or between a contactor and an adjacent device, to manage heat build-up in busy enclosures.

Built for Hager Electrical Systems

As part of the wider Hager Ltd contactor range, the ESC340 is designed to integrate cleanly with Hager distribution board hardware, giving installers a consistent, single-manufacturer solution from incomer to final circuit. Hager Limited manufactures the unit in France to a defined utility category rating (category 7), so it's specified with commercial and light industrial switching duties in mind.
