Power limiter OSP 10 3p 25A 002185014

Power limiter – effective energy consumption control

The OSP 10 3p 25A power limiter is an electrical installation protection element designed to limit the power consumption by the user. It is particularly useful in situations where energy consumption needs to be controlled, e.g. in residential buildings, offices or commercial facilities. This device protects the installation against overload and ensures selectivity in relation to other protective devices.

Construction and application

This limiter is mounted on a DIN rail and is designed to operate in 230/400V AC networks. Its main task is to selectively disconnect the circuit in the event of exceeding the contractually agreed power consumption by the user. Unlike standard circuit breakers, the OSP 10 only has an overload (thermal) element, which means it does not react to short circuits. This is crucial for ensuring the continuity of power supply for devices sensitive to short-term voltage drops. Thanks to the fact that the device has a lock preventing access to the current terminals, the user can re-engage it after activation – without the need for a specialist intervention.

Parameters and benefits

• Rated continuous current: 25 A – provides adequate protection for circuits with a specific power demand.
• Rated conditional short-circuit current: 10 kA – indicates the short-circuit breaking capacity (although the limiter itself does not react to a short circuit).
• Maximum apparent power: 17250 VA – allows you to select the limiter for a specific load and connection power.
• DIN rail mounting: facilitates and speeds up installation in the switchgear cabinet.
• Overload selectivity: ensures that the limiter only operates in the event of exceeding the contractually agreed power, without disconnecting other circuits due to temporary overloads.
• Access lock to terminals: allows the user to re-engage the limiter after it has operated, increasing comfort and reducing costs associated with calling an electrician.

The ETIMAT T power limiter is a solid solution for installers and users looking for an effective way to control energy consumption and protect the electrical installation against overloads. Its construction and operation guarantee reliability and safety of use.
