Learn more by watching our Hager ESC225 | 25Amp 2 Pole Contactor 240V | 2 N/O video.
The Hager ESC225 is a 25A two-pole electrical contactor rated 240V coil voltage, featuring 2 normally open (N/O) contacts and IP20 protection. The ESC225 is controlled by a low-voltage signal to switch much larger AC power loads and is ideal for remote operation of three-phase motors, pool pumps, hot water systems, and other inductive loads requiring automatic or timer-based activation.
Contactors are workhorse components in electrical control circuits where a weak control signal switches a heavy load from a distance. The ESC225 fits quickly and easily into switchboards as a replacement for unreliable relays, making it a natural choice for retrofitting pool heaters, hot water systems, and other inductive loads that have been dodgy or unreliable. The compact DIN rail mount format means electricians can slot the ESC225 onto an existing board in minutes without circuit reconfiguration.
The Hager ESC225 sits in the sweet spot for commercial and industrial applications where a 25A two-pole contactor is the right size for pool equipment, hot water, ventilation fans, or soft-start backup. Operators value the rapid response and smooth operation once the contactor is installed, with easy terminal access for 2–6mm cables and straightforward wiring. Licensed electricians specify the ESC225 when a manual isolator needs to become automatic, and when the load profile justifies a dedicated control circuit instead of relying on soft-starters or variable-speed drives.
The Hager ESC225 is not suitable for DC load switching, explosive atmospheres, or outdoor weatherproof installations. Do not use for loads exceeding 25A at 240V, for DC operation, or in wet or splash-prone locations without an additional IP65 enclosure.

(ESC225)
A toggle switch manually opens or closes a circuit when you flip it. A contactor is an electrically controlled relay that switches power via a low-voltage control signal, allowing remote or automated operation. The ESC225 sits on a switchboard and switches large loads when a timer, relay, or PLC sends a 240V signal to its coil. You do not manually flip the ESC225; it flips automatically in response to a control input.
The ESC225 has two normally open contacts, so it can control a subset of three-phase applications. However, three-phase motor soft-starters and variable frequency drives typically require a three-pole contactor (3NO, 3NC, or 3NO+NC combinations) for full-phase switching and symmetrical load balancing. Consult a licensed electrician to confirm the ESC225 suits your specific motor load and control logic.
The ESC225 accepts rigid cable from 1 to 10mm² per terminal, or flexible cable from 1 to 6mm² per terminal. Tighten the screw terminals firmly to secure the cable and prevent loosening under vibration or thermal cycling. Ensure the cable gauge matches the breaker or overload protection on the load circuit, not just the contactor rating.
Yes. The ESC225 itself does not have built-in overload protection. Install an overload relay or thermal protection device on the motor circuit (separate from the contactor). A circuit breaker or fuse rated to the load current protects the power wiring feeding the load. For safety and compliance with AS/NZS 3000, consult a licensed electrician when specifying the complete control system.
No. The ESC225 is rated for AC operation only, with a 240V AC coil voltage. Do not attempt to energise the coil with DC power, and do not use the ESC225 to switch DC loads. Doing so will damage the coil and the contacts. If you need DC switching, specify a DC-rated contactor.
The ESC225 has an IP20 protection rating, meaning it is dust-tight but not waterproof or splash-resistant. It is rated for indoor switchboards and control enclosures only. For outdoor or damp environments, mount the ESC225 inside a weatherproof IP65 or IP66 enclosure, and ensure the control wiring is also protected.
The Hager ESC225 is available online from Sparky Direct, with Australia-wide delivery to any state or territory including regional areas. Sparky Direct is an Australian electrical wholesaler established in 2005, supplying more than 500,000 customers with transparent trade pricing.
