Power limiter ETIMAT T 3P+N 50A 002181090

Power limiter for protecting electrical installations

The ETIMAT T 3P+N 50A power limiter is an element used to protect electrical circuits against overloads and short circuits. Mounted on a DIN rail, it provides effective protection in three-phase installations with a neutral wire. Its function is to limit the current to a safe level, protecting both devices and wires from damage.

Construction and application

The limiter's construction is based on technology that allows for a quick response to current increase. The rated continuous current of 50A makes it ideal for protecting circuits with medium loads. The rated conditional short-circuit current Iq of 6kA indicates its ability to withstand short-term current surges, which is particularly important when starting devices with motors or other elements generating high inrush currents. The lack of a short-circuit current limiter function means that the device primarily acts as overload protection.

Key features and benefits

• DIN rail mounting: Enables quick and easy installation in electrical switchboards, which translates to time savings during installation.
• Rated current 50A: Suitable for protecting circuits with medium power consumption, providing optimal protection without unnecessary tripping.
• Short-circuit withstand 6kA: Ensures reliable operation in the event of a short circuit, minimizing the risk of damage to the installation.
• 3P+N construction: Designed for use in three-phase circuits with a neutral wire – a standard solution in most building and industrial installations.
• Manufacturer ETI Polam: Guarantee of quality and compliance with applicable standards. ETI Polam is a renowned manufacturer of electrical equipment, known for the solidity and reliability of its products.
