Selective overcurrent switch ETIMAT SM 1p E20 002129201

Selective overcurrent switches – reliable protection of electrical installations

This single-pole overcurrent switch from the ETIMAT SM series is a key element of every safe and efficient electrical installation. Designed for both professional installers and end-users, it provides effective protection against overloads and short circuits. A rated current of 20A combined with an E tripping characteristic guarantees an optimal response to sudden load changes, protecting devices and cables from damage. DIN rail mounting simplifies and speeds up installation, and the compact dimensions allow for efficient use of space in the distribution board.

Functionality and safety in one device

The ETIMAT SM switch is designed for versatility. The ability to seal the lever in the "On" and "Off" positions provides additional protection against unauthorized changes to the switch status. Additional functions, such as the possibility of mounting auxiliary contacts, overcurrent and undervoltage releases, allow the device to be adapted to the specific needs of a given installation. The ON/OFF marking on the switching lever and the contact position indicator facilitate identification of the switch status, which is particularly important during maintenance and repairs.

• Selectivity: Ensures coordinated operation with other protective elements in the installation, minimizing the risk of unnecessary shutdown of the entire installation in the event of a failure on one circuit.
• Universal mounting: Possibility of power supply from above and below, as well as double connection (busbar and cable) increases flexibility during installation.
• Durability and reliability: Made of high-quality materials, resistant to mechanical damage and environmental conditions.
• Marking: Each switch has a unique EAN code to facilitate identification and inventory management.
• Safety of use: Effective protection against contact with live parts (IP20).
• Switching capacity: Rated switching capacity of 25kA guarantees effective circuit interruption in the event of a short circuit.
• Standards and norms: Meets the requirements of overvoltage category 4 and pollution degree 3, ensuring its proper operation in various working conditions. The rated insulation voltage Ui is 690V at a frequency of 50Hz.
