Selective overcurrent switch ETIMAT SM 1p E40 002129204

Overcurrent circuit breaker ETIMAT SM is an element used to protect electrical installations against overloads and short circuits. Model 1P E40, with a rated current of 40A, is used in circuits requiring selective protection, meaning it will only disconnect the damaged section of the installation, allowing the remaining circuits to continue operating.

Characteristics and application

The ETIMAT SM circuit breaker is characterized by a tripping characteristic of type E, which makes it ideal for protecting circuits with devices with high inrush current – such as motors or transformers. Mounting is on a DIN rail, which ensures easy installation and replacement. The rated switching capacity of 25kA guarantees effective circuit interruption in the event of a short circuit. Designed for operation in networks with a rated voltage of 400V and a frequency of 50Hz.

Functionality and benefits

• Tamper-proof: The circuit breaker lever can be sealed in the "On" or "Off" position, preventing accidental change of state and increasing safety.

• Expandability: The ability to mount additional auxiliary contacts, overcurrent and undervoltage releases allows you to adapt the circuit breaker's functionality to the specific needs of the installation.

• Contact position indicator: Allows for quick visual control of the circuit breaker status.

• ON/OFF marking: Clear marking on the switching lever makes operation easier.

• Universal mounting: Possibility of power supply from below or above and connection both to DIN rail and directly with a cable increases flexibility during installation.

• Durable construction: Made of high-quality materials ensures reliable operation and long life.

• Compliance with standards: Meets the required safety standards (IP20 protection class, overvoltage category 4, pollution degree 3).

The ETIMAT SM circuit breaker is a solid and functional solution for both professional installers and end-users looking for reliable protection of their electrical installations. Its versatility and expandability make it an ideal choice for a variety of applications.
