ETI ETIMAT 10 Miniature Circuit Breaker, 3-Pole, Type C, 32A, 10kA

The ETI ETIMAT 10 is a high-performance 3-pole miniature circuit breaker engineered to provide reliable protection for electrical circuits in both residential and industrial environments. This device is designed to detect and interrupt overcurrents, effectively preventing damage caused by overloads and short circuits. With its robust construction and precise tripping mechanism, it ensures the safety of electrical installations and connected equipment by maintaining stable operation under normal conditions and reacting instantly to faults.

Advantages

The ETIMAT 10 offers exceptional reliability due to its high breaking capacity of 10kA, which allows it to handle significant fault currents safely. The C-type tripping characteristic makes it highly versatile, as it is specifically calibrated to handle moderate inrush currents common in inductive loads, such as motors and lighting systems, without nuisance tripping. Its 3-pole design allows for the simultaneous disconnection of all three phases, providing comprehensive protection for three-phase electrical systems and ensuring consistent performance across all connected lines.

Suitable for

• Industrial machinery and motor control circuits
• Residential three-phase power distribution boards
• Commercial lighting installations
• Heating and ventilation systems
• General electrical infrastructure protection

When it may not be suitable

This circuit breaker is not intended for use in DC electrical systems, as it is designed specifically for AC applications. Furthermore, it may not be appropriate for circuits requiring a B-type tripping characteristic, where sensitive equipment demands faster reaction times to lower surge currents.

Key specifications

• Number of poles: 3
• Rated current: 32A
• Tripping characteristic: Type C
• Breaking capacity: 10kA
• Mounting type: DIN rail

How to use

The ETIMAT 10 is designed for installation on a standard DIN rail within an electrical distribution board. The device should be installed by a qualified electrician in accordance with local electrical regulations. Ensure that the supply cables are securely fastened to the terminals and that the wire cross-section is appropriate for the 32A rated current. Once installed, the toggle switch can be used to manually connect or disconnect the circuit, while the internal mechanism will automatically trip the switch to the off position in the event of an electrical fault.

What to consider before purchase

• Verify that the 32A rating matches the requirements of your electrical circuit and connected load.
• Ensure the 10kA breaking capacity is sufficient for the prospective short-circuit current at the point of installation.
• Confirm that the C-type tripping curve is compatible with the starting currents of your equipment.
• Check the available space in your distribution board for a 3-pole modular device.

Usage recommendations

Regularly inspect the circuit breaker for signs of physical damage or discoloration. It is recommended to perform a periodic functional check by operating the toggle switch to ensure the mechanism remains smooth and responsive. If the breaker trips, investigate the cause of the overload or short circuit before resetting the device.
