open frame relay Datasheet / information needed

[tebara]

I need datasheet or detail information for this relay.
Thank you.

Hello, is something written on its body? No model number or something?

Are you sure this is a relay? It looks more like a circuit breaker with a reset button to me.

Why do you need it the datasheet? What caused this concern?

It looks like a typical RCCB. If I'm not mistaken EU has much higher ratings than but are 25 to 30 mA for small units while North America calls them RCD and are rated at 20 mA imbalance from leakage.

Wikiwand - Residual-current device

A residual-current device (RCD), residual-current circuit breaker (RCCB) or ground fault circuit interrupter (GFCI) is an electrical safety device that interrupts an electrical circuit when the current passing through a conductor is not equal and opposite in both directions, therefore indicating...

It is basically a very high inductance CM choke that acts as a solenoid to trip the breaker on imbalanced AC currents with the presumption that is caused by unsafe external leakage to ground

Hi, just as picture, no more data!

Hi,
No I'm not. But could not find any information/component/manufacturer.

Hi,
Thank you for detailed information, its in a PRCD and its rating is 10mA.
I want to know the manufacturer and coil resistance.

Not sure if it will help. You can post the pic and rating in digikey forum. Sorry. This relay is not familiar to me.

Why don't you get one and measure it.
What value of L and R would you expect for each winding?

The R is about 3.57 K. Do you any supplier for this, I could not find any.

 

[D.A.(Tony)Stewart]

Or what impedance value of L and R would you expect to trigger a spring-loaded solenoid with a 10mA common-mode current with 240Vac available on the main core windings?

How much winding power could be tolerated before tripping at 10 mA?
How much flux do you need to trip

The R is about 3.57 K. Do you any supplier for this, I could not find any.

I doubt anyone can recognize the supplier from the internal photo.

But for a shopping question, this is a different challenge. I found this.

There are many options and 10 mA is one of them.
