Selective overcurrent circuit breaker ETIMAT SM 3p E40 002129224

Overcurrent circuit breaker ETIMAT SM is a reliable protection for electrical installations, designed for both domestic and industrial applications. The three-pole E40 model, with a rated current of 40A, provides effective protection against overloads and short circuits. Its selective tripping characteristic (E) allows for coordinated operation with other circuit breakers in the circuit, minimizing the risk of unnecessary tripping of the entire installation in the event of a failure on one section.

Features and application

The ETIMAT SM circuit breaker is designed for mounting on a DIN rail, which facilitates its installation and replacement. The rated switching capacity of 25kA guarantees safety even in the event of high short-circuit currents. The device meets the requirements of overvoltage category 4 and pollution degree 3, making it suitable for operation in various environmental conditions. Thanks to the rated voltage of 400V and the insulation voltage Ui 690V, the circuit breaker can be used in a wide range of electrical installations.

Functionality and benefits

• Selectivity: Characteristic E provides a delayed response to short-term overloads, which is particularly important when connecting devices with motors or other loads with high inrush current. This avoids unnecessary tripping of the circuit when starting devices.
• Versatile mounting: The possibility of power supply from below or from above and connection with both a busbar and a cable increases the flexibility of the installation.
• Safety of use: Protection class IP20 provides protection against accidental contact, and the ability to seal the lever in the "Off" and "On" positions prevents unauthorized changes to the circuit breaker status.
• Expandability: The circuit breaker can be equipped with auxiliary contacts, overcurrent and undervoltage releases, adapting it to specific application needs.
• Contact position indicator: A clear indicator (green - off, red - on) facilitates quick identification of the circuit breaker status.
• Durable construction: Made of high-quality materials, it ensures long-lasting and reliable operation.

ETIMAT SM circuit breakers are an ideal solution for installers looking for reliable and easy-to-install protection and for end-users who value safety and comfort of use.
