DC overcurrent circuit breaker ETIMAT 10-DC 1P C0.5 6kA 002137701

DC Installation Protection – Reliable ETIMAT 10-DC Circuit Breaker

The ETIMAT 10-DC circuit breaker is a compact and efficient protection for direct current (DC) circuits. Designed to protect against overloads and short circuits, it ensures the safety of installations in various applications, from photovoltaic systems to DC power supplies. Its modular design (1 module width) simplifies installation in distribution boards.

Functionality and parameters

This single-pole (1P) circuit breaker with a rated current of 0.5 A is characterized by a C tripping curve. This means it is ideal for circuits where short-term current surges occur, e.g., when starting devices with a motor. The rated short-circuit breaking capacity Icn is 6 kA at both 230 V and 400 V, guaranteeing effective protection in the event of a failure. The energy limitation class is 3.

Key features of this circuit breaker include: a rated current of 0.5 A ensures precise matching to the protected circuits, and the C tripping curve is suitable for loads with short-term current peaks. A short-circuit breaking capacity of 6 kA guarantees high effectiveness in emergency situations. The rated voltage is 220 V, providing versatility in typical DC installations. The circuit breaker operates in a wide temperature range from -25°C to +55°C and has an IP20 protection rating – protects against touching with a finger and solid objects with a diameter greater than 12.5 mm.

Installation and application

The ETIMAT 10-DC circuit breaker is easy to install on a TH35 rail (standard mounting rail in distribution boards). The possibility of additional accessories allows it to be adapted to the specific requirements of the installation. It will be useful in:

• Photovoltaic systems – protection of solar panels and inverters.
• DC power supplies – protection of electronic devices sensitive to overvoltage and short circuits.
• DC lighting installations – ensuring the safety of using LED lighting and other light sources powered by direct current.
• Industrial applications – protection of DC control and power supply circuits.

Thanks to its compact size and high reliability, the ETIMAT 10-DC circuit breaker is an optimal solution for both professional installers and end-users looking for effective protection of their DC electrical installations.
