Power limiter Eti-Polam OSP-10 1P 20A (model 002181013)

The Eti-Polam OSP-10 single-pole power limiter rated for 20 A is designed to control and cap electrical consumption in single-phase installations. It provides a compact solution for preventing excessive current draw by limiting the maximum allowed load in circuits where power management and basic protection against overloads are required. The unit is intended for integration into residential and commercial distribution boards and is compatible with standard DIN-rail mounting and single-phase supply systems.

Advantages

The device offers a precise current limiting function for a single pole, enabling stable control of connected loads and reducing the risk of tripping upstream protection. Its compact design minimizes space in distribution enclosures while delivering reliable performance under normal operating conditions. The limiter is manufactured to industry norms for electrical safety and provides a straightforward method to enforce a 20 A consumption limit without complex configuration.

Suitable for

• Limiting power consumption in single-phase residential electrical panels
• Controlling load in small commercial or retail installations
• Protecting circuits where a fixed current cap is required to prevent overloads
• Integration with energy management setups that require hardware current limiting

Key specifications

• Poles: single-pole (1P)
• Rated current limit: 20 A
• Designed for single-phase circuits
• Mounting type: DIN-rail compatible
• Application: power/current limiting for distribution systems

How to use

Install the power limiter in the distribution board on a compatible DIN rail and connect it in series with the load on the phase conductor of the single-phase circuit to be limited. Ensure that the incoming supply and outgoing load conductors are connected according to local wiring practices and that the device is accessible for inspection. Verify that upstream protective devices (such as main breakers or fuses) are coordinated with the 20 A limit before energizing the circuit. After installation, test the circuit under controlled conditions to confirm the limiter enforces the intended current cap.

Usage recommendations

Use the limiter where a clear, fixed current cap is needed and avoid deploying it on circuits with motor loads or high inrush currents unless coordination with protective devices has been verified. Regular visual inspection and periodic testing in accordance with local electrical regulations are recommended to ensure continued correct operation.
