Power limiter ETIMAT T 1p 50A 002181084

Power limiter ETIMAT T is a device for protecting electrical installations, designed to limit the power consumption of the user. This device is primarily used as a pre-meter protection, allowing selective disconnection of the circuit in case of exceeding the contracted power. This is particularly important in installations where energy consumption control and protection against overloads are necessary.

Characteristics and application

ETIMAT T is an overcurrent circuit breaker that has only an overload element (thermal) – it does not have a short-circuit protection element. This means that it reacts to long-term exceeding of the permissible current, protecting the installation from overheating and damage. The use of a power limiter allows for selective operation in relation to overcurrent protection on the user side, which is crucial for ensuring uninterrupted power supply and minimizing downtime. Mounting is done on a DIN rail, which facilitates integration with the existing electrical infrastructure.

Advantages and benefits

• Power consumption limitation: Enables control of energy consumption by the user, which translates into savings and avoidance of unplanned costs.
• Selectivity: Ensures selective disconnection of the circuit in case of overload, without affecting the operation of other protections in the installation.
• Simple installation: DIN rail mounting makes installation easier and faster.
• Overload protection: Protects the electrical installation from damage caused by long-term exceeding of the permissible current.
• User accessibility: The operating lever is accessible to the user, allowing self-re-engagement of the circuit breaker after it has tripped (after removing the cause of the overload).

Technical parameters and construction

The ETIMAT T 1p 50A power limiter is characterized by a rated continuous current of 50A and a short-circuit breaking capacity of up to 6kA. The device construction is based on a proven bimetallic technology, ensuring reliable operation in various working conditions. The lack of a short-circuit element means that the device reacts only to overloads, which ensures its selectivity with other protections in the installation. The rated conditional short-circuit current Iq is 6kA. The device meets the requirements of the PN-IEC 60898-1:2007 standard. The terminals of the limiter allow connection of wires with a cross-section from 1 to 25 mm², with a maximum tightening torque of 3 Nm.
