Overcurrent protection device OSP 10 1P 15A 002181012

Protection of installations and devices – power limiter OSP 10

The OSP 10 power limiter is a protective element, mounted on a DIN rail, which effectively protects electrical circuits from the effects of overvoltages and short circuits. Its task is to limit the current to a safe level, minimizing the risk of damage to connected devices and wires. This is a simple but crucial solution in every electrical installation.

Construction and application

This limiter is designed to work with circuits with a rated continuous current of 15A. Its D-characteristic design ensures a quick response in the event of overloads, but also allows for short-term loads without unnecessary tripping – which is particularly important for devices with induction motors or other elements generating surge currents. The rated conditional short-circuit current at 10 kA guarantees effective protection even in the event of serious disturbances in the network.

• Mounting is done on a standard DIN rail, which facilitates integration with the existing switchgear.
• This limiter finds application in building installations (apartments, houses, offices), as well as in industrial and commercial facilities.
• It is ideal for protecting lighting circuits, socket outlets and electrical devices sensitive to overvoltages.
• Thanks to its compact dimensions (18 mm wide) it does not take up much space in the switchgear.

Key features and benefits

• Effective protection: Protects against overloads and short circuits, protecting the installation and connected devices from damage.
• D-characteristic: Allows for momentary overloads without tripping – ideal for devices with motors.
• Easy installation: DIN rail mounting method ensures quick and easy installation.
• Compact dimensions: Allow mounting in tight spaces in the switchgear.
• High reliability: Guarantees long-lasting and trouble-free operation of the protection system.
