Why it Matters

Switch four things at once.
The ESC425 gives you four normally open poles on a single 230V AC coil, so all four circuits stay isolated at rest and close together the instant the coil is energised. That makes it the go-to for switching a three-phase load plus neutral, or several separate single-phase circuits, from one remote command – a timer, control switch or building management system – rather than wiring in multiple smaller contactors.

Four poles, two modules.
Despite carrying four poles, the ESC425 occupies just two DIN modules (35.75mm wide, 83mm high, 60mm deep) on standard 35mm rail, so it drops into compact boards where space is at a premium. Terminals accept rigid conductors up to 10mm² at a 1.2Nm tightening torque, and it is rated for 100,000 mechanical operations and 30,000 electrical cycles for long service in regularly cycled circuits.

Sized for the Australian board.
The ESC425 is rated 25A under the AC-7a/AC-7b utilisation categories – covering slightly inductive household-type and household-motor loads – at up to 400V, so it handles three-phase lighting, heating banks and small motors as well as multiple single-phase circuits. It operates from -10°C to 50°C to suit meter boxes, plant rooms and commercial distribution boards. An ESC080 auxiliary contact and LZ060 heat dissipation insert are available from Hager where needed.

Q: What can the Hager ESC425 switch?
Four normally open poles rated 25A, letting it switch a three-phase-plus-neutral load or several single-phase circuits together on a 230V AC coil command.

Q: How much DIN space does the ESC425 take?
Two modules, 35.75mm wide, 83mm high and 60mm deep, on standard 35mm DIN rail.

Q: Does the ESC425 switch on or off when energised?
Its four poles are normally open, so they close (switch the loads on) when 230V AC is applied to the coil and open again when the coil is de-energised.
