Power limiter ETIMAT T 3p 40A 002181065

Power limiter ETIMAT T – reliable installation protection

The ETIMAT T 3P 40A power limiter is a device designed for mounting in a distribution board, functioning as a pre-meter protection. Its main task is to selectively disconnect the circuit in the event of exceeding the permissible power, protecting both the installation and the devices connected to it. It is an alternative to traditional selective circuit breakers, offering effective protection against overload.

Construction and application

The limiter's construction is based on a circuit breaker without a short-circuit release, equipped only with a thermal release. This means that it reacts to long-term exceeding of the rated current, not to short-term surges. Thanks to this, it is ideal for protecting receivers with a characteristic power consumption profile, such as electric heating or devices with motors. The limiter should be installed by a qualified electrician, and its drive lever should be easily accessible to the user – allowing them to re-engage it independently after intervention.

Key features and benefits

• Selectivity: Provides selective disconnection in relation to Z4 receiver protection, minimizing the risk of unnecessary disconnection of the entire installation.
• Overload protection: Protects the circuit against long-term exceeding of the rated current, preventing damage to wires and devices.
• Simple operation: Accessible drive lever allows the user to re-engage the limiter independently after intervention.
• DIN rail mounting: Standard DIN rail mounting simplifies integration with the existing distribution board.
• Rated short-circuit capacity: Withstands short-circuit currents up to 6 kA, ensuring safety in the event of a failure.
• Adapted to work in difficult conditions: A wide range of operating temperatures (-25°C to +50°C) guarantees reliable operation in various environments.

Technical data in brief

• Rated continuous current (Iu): 40 A
• Rated conditional short-circuit current (Iq): 6 kA
• Mounting method: DIN rail
• Rated voltage: 400 V AC
