Hager ESC240 Modular Contactor 40A 2 Pole 2NO 230V AC Coil 3 Module DIN Rail Mount

Description

Heavier switching, still DIN-simple.

The Hager ESC240 is a 40A modular contactor with two normally open (2NO) contacts and a 230V AC coil, built for remote switching of lighting, heating and small motor loads. Its 3-module DIN rail body suits residential and commercial distribution boards.

Why it Matters

Step up to 40A switching.
The ESC240 is the 40A member of Hager's modular contactor range, giving you a bigger switching capacity than the 25A ESC225 while keeping the same normally open logic: both poles stay open at rest and close when 230V AC is applied to the coil. It is the part to reach for when a lighting bank, electric heating circuit or larger single-phase load has outgrown a 25A contactor but the job still calls for remote, control-circuit switching rather than a full industrial contactor.

Ratings you can size against.
Hager rates the ESC240 at 40A for AC1 resistive-type loads and 25A for AC3 motor duty, under the AC-7a/AC-7b utilisation categories that cover slightly inductive household-type and household-motor loads. Larger terminals accept rigid conductors from 1.5 up to 25mm² (flexible to 16mm²), matching the heavier cabling a 40A circuit typically runs. Endurance stays at 100,000 mechanical operations and 30,000 electrical cycles.

Built for the Australian board.
The ESC240 occupies three DIN modules (54mm wide, 85mm high, 60mm deep) on standard 35mm rail, so allow the extra space beside your protection when you plan the switchboard. It runs from -10°C to 50°C, comfortably covering meter boxes, plant rooms and commercial distribution boards in Australian conditions. An ESC080 auxiliary contact and LZ060 heat dissipation insert are available from Hager where the install needs them.

Q: Is the Hager ESC240 a single-phase or three-phase contactor?
It is a 2-pole (2NO) contactor with a 230V AC coil, used to switch single-phase loads or two poles of a circuit; for three-pole switching Hager offers 3NO models such as the ESC340.

Q: What size cable can the Hager ESC240 terminals take?
Rigid conductors from 1.5 to 25mm² and flexible conductors from 1.5 to 16mm².

Q: How many DIN modules does the ESC240 take up?
Three modules, 54mm wide, 85mm high and 60mm deep, on standard 35mm DIN rail.
