Overcurrent protection device OSP 10 1p 20A 002181013

Protection of installations and devices – power limiter OSP 10

This single-pole power limiter, with a rated current of 20A, is a key element in protecting the electrical installation from the effects of overvoltage and overloads. Designed for DIN rail mounting, it effectively protects circuits from damage caused by sudden voltage surges, which translates to a longer lifespan of connected devices.

Functionality and application

The OSP 10 limiter is designed to protect against the effects of short circuits and overloads in electrical circuits. Its D tripping characteristic provides a delayed response to short-term current increases, which is particularly important when connecting receivers with motors or other elements generating high inrush currents. This reduces the risk of unnecessary tripping of the circuit during normal operation. The apparent power of 4600 VA makes it suitable for protecting a variety of receivers.

Key features and benefits

• Effective short-circuit protection: The rated conditional short-circuit current of 10 kA guarantees a quick response in the event of a short circuit, minimizing the risk of damage to the installation and fire.
• DIN rail mounting: Enables easy and quick installation in electrical switchboards, saving time and installation costs.
• D characteristic: Delayed tripping allows for trouble-free starting of devices with high inrush currents, such as motors or transformers.
• Versatile application: Suitable for protecting various electrical circuits in residential, commercial and industrial buildings.
• High reliability: Ensures long-lasting and stable operation, minimizing the risk of failure and downtime.
• Compact dimensions: Facilitate installation even in tight spaces inside the switchboard (width 18 mm, height 85 mm, depth 68 mm).
