Hager ESC226 Modular Contactor 25A 2 Pole 2NC 230V AC Coil 1 Module DIN Rail Mount

Description

Fail-safe switching in a single module.

The Hager ESC226 is a 25A modular contactor with two normally closed (2NC) contacts and a 230V AC coil, built for remote switching of lighting, heating and ventilation loads. Its 1-module DIN rail design keeps space free in crowded residential and commercial switchboards.

Why the 2NC Configuration Matters

Circuits that stay on until you tell them not to.
With two normally closed poles, the ESC226 keeps its circuits connected while the coil is at rest and opens them the moment the 230V coil is energised. That inverted logic is exactly what you want for interlocking, shutdown and fail-safe control schemes, where a load must be positively disconnected on command rather than switched on. Hager pairs this with efficient remote operation, so the contactor can sit in the board and be driven from a control circuit anywhere in the installation.

Built for Australian switchboards.
At just one module (17.85mm) wide and 60mm deep, the ESC226 clips onto standard 35mm DIN rail alongside your circuit protection, leaving room in compact domestic boards and tightly packed commercial distribution boards alike. Terminals take rigid conductors up to 10mm² with a 1.2Nm tightening torque, and the unit operates from -10°C to 50°C, comfortably covering Australian ambient conditions in garages, plant rooms and outdoor-rated enclosures.

Rated for the loads sparkies actually switch.
The AC-7a/AC-7b utilisation categories cover slightly inductive household-type loads and motor loads for household applications, making the ESC226 a natural fit for controlling lighting banks, heating circuits and ventilation equipment in homes, apartments and light commercial fit-outs. With 100,000 mechanical operations and 30,000 electrical cycles of rated endurance, it is a set-and-forget component that will outlast most control schemes it is wired into.

Q: What does 2NC mean on the Hager ESC226 contactor?
2NC means both poles are normally closed: the contacts conduct while the coil is de-energised and open when 230V AC is applied to the coil, suiting shutdown and interlocking duties.

Q: How much DIN rail space does the Hager ESC226 take up?
Just one module, 17.85mm wide, 83mm high and 60mm deep, so it fits a single pole space in a standard switchboard.

Q: What loads is the Hager ESC226 rated to switch?
It carries utilisation categories AC-7a and AC-7b at 25A, covering slightly inductive household-type loads such as lighting, heating and ventilation circuits driven by motors for household applications.
