Heschen Household AC Contactor, CT1-25, 2 Pole, Two Normally Open, AC 220V/230V Coil Voltage, 35 mm DIN Rail Mount (1)

I cannot fault these relays. They are used to switch 2 and 3 kW loads on a pretty regular basis. I find them fully up to the level of quality and performance that I would get from the more common industrial control relays I used to fit, they of course came in at nearly four times the cost of these.I have ordered a couple more as I am finding it advantageous financially to move away from central heading and heat areas of the house locally. These relays allow more accurate control via a small controller and also allow the incorporation of a timer to ensure that the heating is off when no one is in the vicinity for a period.

Used this as a fail-safe to operate a dc48 volt sensing circuit in an automatic change over control unit. Just two issues that convince me to look elsewhere. 1/ it’s noisy. The a/c coil hums which is noticeable and resonates. Not a problem in a switch room but could be a nuisance in residential property. 2/ when power is removed there’s a short (noticeable) delay before contacts are released. Can be fixed but better/appropriate relays (circuits) are available.Otherwise a simple and solid solution.

Works well so far; with no issues

I couldn’t find coil consumption data anywhere so I measured it with a multimeter: 15mA at 240V 50Hz, which results in 3.6VA which I think is ordinary but ideally would be less. Giving it 4 stars rather than 5 because of the coil’s humming noise that can be heard even from outside the cabinet where it was fitted (hard surfaces amplify the sound).

Used this to operate a hot air, curtain over a door, a sensor energises the mag switch when the door opens ( and automatically switches off power when the door is closed )

Working fine

They run cool and have been reliable. I have purchased the latest relays for standby. As I am well suited with them

Works for intended purpose of smart plug control of immersion heater. The relay click is more of a thud that is very loud and can wake you up.
