Product Features

- A breaking capacity of 12kA up to 32A and 10kA between 40 to 63A.

- Current-limiting scheme: in the event of a short circuit, are able to limit the let-through current to 60%-70% of the rated current.

- The trip mechanism ensures perfect closure every time,thereby considerably improving the performance of these devices and extending their average lifetime.

-The arc extinguishing system: allows the short-circuit currents of very high value to be interrupted extremely rapidly, the remarkable opening speed of contacts opening and the structure of the arcing chamber contribute to extinguishing the arc in the shortest possible time, ensuring reliable protection of short-circuit.

- The internal contact position allows an exact information of the circuit-breaker status: “green”,open contacts;“red”,closed contacts,independently of the toggle position.

- Sealing/locking sealable with 1 mm wire, to prevent unwanted tripping.

- The supply lines of the protected circuit can be connected to either the upper or lower terminals of the circuit-breakers(reversibility of connections).

- The double terminal of these circuit-breakers enables simultaneous connection of cables and busbars.

This is my Open EVSE installation which will go into my shed for charging my future Tesla Model S.

The EVSE is for use in Europe, so it’s a 3-phase 32A (22kW) installation.

In the small box is the OpenEVSE board with a small relais, this small relais switches on the big relais in the main panel.

The big relais is 40A 4p and is the most right on the upper row.

The layout of the main panel (left to right)

Top:
- 16A breaker for EVSE itself
- 12V transformer for switching on big relais
- 40A 4p relais (ESL 440S)

Bottom:
- 40A CFGI
- 4p 32A breaker, goes directly to big relais
- 4p 16A breaker, for an auxillery 3-phase connection
