Hager ESC440 Modular Contactor 40A 4 Pole 4NO 230V AC Coil 3 Module DIN Rail Mount

Description

Four heavier circuits, one command.

The Hager ESC440 is a 40A four-pole modular contactor with four normally open (4NO) contacts and a 230V AC coil, built to switch several lighting, heating or motor circuits together from a 3-module DIN rail body.

Why it Matters

Switch four circuits, stepped up to 40A.
The ESC440 gives you four normally open poles on a single 230V AC coil: all four circuits stay isolated at rest and close together the instant the coil is energised. It is the 40A member of the four-pole normally open range, so where the 25A ESC425 handles lighter duty, the ESC440 takes the heavier three-phase-plus-neutral loads and larger multi-circuit banks switched from one remote command – a timer, control switch or building management system.

Genuine dual ratings and bigger cable.
Hager rates the ESC440 at 40A for AC1 resistive-type loads and 25A for AC3 motor duty, under the AC-7a/AC-7b utilisation categories. Its larger terminals accept rigid conductors from 1.5 up to 25mm² (flexible to 16mm²) at a 1.2Nm tightening torque, matching the cabling a 40A four-pole feed runs, and endurance is rated at 100,000 mechanical operations with 30,000 electrical cycles.

Plan the board space and cooling.
The ESC440 occupies three DIN modules (54mm wide, 85mm high, 60mm deep) on standard 35mm rail, so allow room beside your protection in the switchboard. It runs from -10°C to 50°C to suit meter boxes, plant rooms and commercial distribution boards in Australian conditions. With 14.3W dissipation at full load an LZ060 heat dissipation insert from Hager is worth fitting where contactors sit side by side; an ESC080 auxiliary contact is also available.

Q: What can the Hager ESC440 switch?
Four normally open poles rated 40A (AC1) and 25A (AC3), letting it switch a three-phase-plus-neutral load or several single-phase circuits together on a 230V AC coil command.

Q: What cable sizes fit the ESC440 terminals?
Rigid conductors from 1.5 to 25mm² and flexible conductors from 1.5 to 16mm², at a 1.2Nm tightening torque.

Q: How many DIN modules does the ESC440 take up?
Three modules, 54mm wide, 85mm high and 60mm deep, on standard 35mm DIN rail.
