Learn more by watching our Hager ESC125 | 25Amp 1 Pole Contactor 240V video.
The Hager ESC125 is a single-pole electrical contactor rated 25 Amp 240V AC, designed to switch high-current loads under remote control. The ESC125 uses a low-voltage coil to control a main circuit carrying significantly higher current, making it ideal for applications where a timer or control device cannot directly carry the load. It mounts on standard DIN rail and accepts wire sizes from 1 to 10 mm² (solid) or 1 to 6 mm² (flexible).
Hot water systems, pool pumps, and large lighting arrays frequently require a contactor because standard timers and switches are rated for lower currents. The ESC125 bridges this gap, allowing electricians to wire a timer or control switch to a low-voltage coil circuit, which then switches the main load safely and reliably. This separation of control voltage and load voltage is a proven industrial pattern that simplifies installation and increases safety margins on residential and commercial retrofit work.
Licensed electricians specify the ESC125 for situations where a standard timer or switch is under-rated for the job. The contactor accepts 25 Amp AC load at 240V on its single normally open (1NO) contact, while the coil operates at 230V AC command voltage. Switching time is fast (25 ms close, 15 ms open), and the device is rated for 30,000 electrical cycles and 100,000 mechanical operations, ensuring long service life on intermittent duty schedules. The IP20 protection rating suits indoor switchboard installation; exposure to water or dust requires an enclosure. No local manual operation is possible on the ESC125 (it switches only on voltage command), so a separate isolator switch is required for safe maintenance access.
The Hager ESC125 is not suitable for AC currents exceeding 25A, for DC circuits, or for hand-operated switching. It is a contactor for electrical control engineers and licensed sparkies only; incorrect wiring of the coil or load circuit creates a shock and arc hazard.
Verified Sparky Direct customer reviews: Hager ESC125 | 25 Amp 1 Pole Contactor 240V (ESC125)
"When the analog timer won't carry the load, switch it with a simple contactor" — Tready
"Perfect for our needs, and great service from the Sparky direct team" — Alan
"Quality product, packaged well, order was quick" — Andrew
(ESC125)
Standard timers are rated for low-voltage loads (typically 10A). A hot water element drawing 20-25A on 240V will overheat and fail a standard timer's contacts. The ESC125 allows the timer's low-current circuit to control the contactor coil, which then safely handles the 25A load. This is the standard practice in electrical installation.
Yes. The ESC125 coil accepts any 230V AC signal—from a mechanical timer, a digital programmer, a thermostat, a relay, or a solar controller. As long as the control voltage is 230V AC and the coil current draw stays within the manufacturer limits, the ESC125 will respond.
Yes, the ESC125 can be protected by an RCD, but inductive loads (motors, compressors) can cause nuisance tripping. If you experience frequent tripping, consult a licensed electrician about upgrading to an RCD-rated for inductive loads or installing a surge suppressor across the load.
The ESC125 is rated for 25A continuous at 240V. Smaller relays typically max out at 16A. The ESC125 has larger contacts and faster switching action, making it suitable for higher-current, higher-duty applications. The 30,000 electrical cycle rating also exceeds most panel relays.
No. The ESC125 carries an IP20 rating, which means it is suitable for indoor dry switchboards only. It is not dustproof or waterproof and should not be exposed to splash, rain, or condensation. Mount it inside an enclosed switchboard or a weatherproof DIN enclosure if external placement is necessary.
The ESC125 coil draws approximately 2.9 watts during normal operation. This is negligible and will not cause measurable impact on your household or building power draw. Inrush during the switch closure is 10.7 VA (peak), but this lasts only 25 milliseconds and is absorbed by standard wiring.
No. The ESC125 has no hand lever or mechanical bypass. If the coil loses power, the contacts open immediately and cannot be forced closed manually. For maintenance or safe isolation, you must install a separate manual isolator switch upstream of the contactor, per electrical code requirements.
Listen for an audible click when the coil energises (the contacts closing). Check that the controlled load (e.g., hot water element) energises immediately when the coil is on, and de-energises immediately when the coil is off. Use a multimeter to verify 230V AC across the coil terminals during operation. If the click is missing or the load does not respond, suspect a burned coil or seized contacts and replace the contactor.
