The ETIMAT 10 series circuit breakers rated above 63A are designed to protect high-power AC circuits from overloads and short circuits. They are intended for use in main distribution panels, industrial electrical installations, and infrastructure facilities with high operating loads. Rated currents range from 80 A to 125 A (depending on the model), and the breaking capacity reaches 10 kA at 230/400 V AC. Thanks to their high mechanical and electrical durability, the devices ensure stable operation even under demanding operating conditions.
Technical advantages
- High rated currents: 80 A, 100 A, and 125 A — ideal for main power supply lines and large consumer groups.
- Breaking capacity: up to 10 kA at 230/400 V AC.
- Two-stage protection: thermal and electromagnetic trip units for effective response to overloads and short circuits.
- Improved arc-quenching chambers: increased number and size of plates for rapid arc quenching at high currents.
- High switching durability: silver-plated power contacts for stable current conduction.
- Compatibility with accessories: block contacts, independent trip units, sealing panels, and other modules.
- Robust housing: heat-resistant plastic, resistant to heat and mechanical damage.
Features
ETIMAT 10 over 63A are designed for power supply from high-power transformers or generators, where short-circuit currents can reach significant values. Their design includes extended contact groups and a reinforced arc-quenching system. The circuit breakers feature standard modular mounting on a DIN rail or built-in mounting in a panel, facilitating integration into existing systems.
The handle can be sealed in the ON/OFF position, and additional contacts can be installed for remote monitoring and control. The devices feature clear status indicators and labeling, simplifying line identification within the panel.
Applications
ETIMAT 10 over 63A are used for:
- Main power supply inputs in industrial and commercial buildings.
- Protecting main lines and sections of distribution panels.
- Powering high-power-consumption equipment (large motors, compressors, process systems).
- Sectionalizing large electrical networks with high short-circuit currents.
- Facilities in the energy, transportation, and housing and utilities sectors where a reliable high-power switching device is required.
Accessories
For ETIMAT 10 rated above 63A, the following are available:
- PS ETIMAT 10 contact blocks — transmission of the circuit breaker status signal to the control system.
- DA ETIMAT 10 independent trip units — remote disconnection in case of a fault or a command from the automation system.
- Sealing panels — restricting access to control elements.
- Terminal caps — protection against contact with live parts.
