Calculating Electrical Life of PK-1Z-LED 230V Relay for 100W LED Strips

Hello colleagues Could someone please give a hint How is the relay life calculated The relay will be fitted to the led strips which operates a 100 watt 5A power supply . MAX consumption 40A according to the data sheet at start up. I have purchased a PK-1Z-LED 230 V relay where it has a written Electrical life min. 1×10⁵ cycles. Is there any way to calculate how long such a relay can last? It will light up the corridor at night, so I assume it will switch on at night about 5 times a day. If anyone would like to share their knowledge on how to calculate this I would be grateful
I'm just asking out of curiosity because for example I have INT-Ors roller-blinds mounted there, probably Relpol relays inside. The roller-blinds have been operating for 8 years now and there have been no problems with these relays.

Put the relay on and let it work, not figure out how much it should work. It is one thing to switch active power and another to switch reactive power in addition.

I'm more curious about how long such a relay can last temporarily, I realise that this depends on many factors.

That is 10 cycles per day (assuming 1 cycle is on or off). Life is 100,000 cycles -> 100,000/10 = 10,000 / 365 = approximately 27.4 years.

Thank you very much for the hint, I realise that it depends on many factors. Where I have made switching on the dc side it already works 3 years and here it is difficult because there is no cable and only full-circuit control and power supplies is already different when switching leds because they do practically and short-circuit current and for this reason so out of curiosity on Sunday asked again thank you .

Hi,

Install an electronic relay and you won't have a problem with lifetime and contact burnout

Greetings.

I already have a couple of ssr mounted and it works , but in this case I'm afraid of overvoltage because next to a lot of photovoltaics from the grid is so that someone boosts the voltage and in the location appears even 260v on the phase not always but quite often.Therefore I am afraid of damage.
