Hager ESC225 Modular Contactor 25A 2 Pole 2NO 230V AC Coil 1 Module DIN Rail Mount

Description

Remote load switching from a single module.

The Hager ESC225 is a 25A modular contactor with two normally open (2NO) contacts and a 230V AC coil, made for remote switching of lighting, heating and small motor loads. Its 1-module DIN rail format installs quickly in residential and commercial distribution boards.

Why it Matters

The workhorse switching logic.
With two normally open poles, the ESC225 keeps its circuits isolated at rest and closes them when 230V AC is applied to the coil, which is the standard arrangement for remotely switching lighting banks, heating circuits and small motor loads from a timer, control switch or building control circuit. Both poles switch together, so active and neutral (or two actives) can be broken in one operation for safe isolation of the load.

Genuine ratings for real loads.
Hager publishes both an AC1 rating of 25A for resistive-type loads and an AC3 rating of 8.5A for motor duty, alongside AC-7a/AC-7b utilisation categories covering slightly inductive household-type loads and motor loads for household applications. That means you can size it honestly against what is actually being switched, rather than working from a single headline number. Endurance is rated at 100,000 mechanical operations and 30,000 electrical cycles.

Made for tight Australian boards.
At one module (17.85mm) wide, 83mm high and 60mm deep, the ESC225 takes a single pole space on standard 35mm DIN rail next to your breakers and RCDs. Terminals accept rigid conductors up to 10mm² at a 1.2Nm tightening torque, and the contactor operates from -10°C to 50°C, suiting meter boxes, plant rooms and switchboards across Australian conditions. An ESC080 auxiliary contact and LZ060 heat dissipation insert are available from Hager if the installation calls for them.

Q: What does 2NO mean on the Hager ESC225 contactor?
2NO means both poles are normally open: the contacts are open while the coil is de-energised and close when 230V AC is applied, so the load only runs when the control circuit calls for it.

Q: What is the difference between the AC1 and AC3 ratings on the ESC225?
AC1 (25A) covers non-inductive or slightly inductive loads such as resistive heating, while AC3 (8.5A) is the lower rating that applies when switching motor loads.

Q: How much switchboard space does the Hager ESC225 need?
One DIN module: 17.85mm wide, 83mm high and 60mm deep, mounting on standard 35mm DIN rail.
