Surge Protector FF OP-230 2P 1 kV with triple interference filter (Type D)

FF OP-230 2P 1 kV with triple interference filter (Type D) is a two-pole surge protector designed for low-voltage installations. It provides transient overvoltage suppression up to 1 kV and integrates a triple interference filter to reduce electromagnetic and radio-frequency disturbances. The device is intended for residential and light-commercial electrical panels and for protecting connected equipment that requires both surge protection and improved electromagnetic compatibility (EMC).

Advantages

The surge protector combines two-pole transient suppression with a three-stage interference filter, offering coordinated attenuation of high-energy transients and common-mode or differential-mode electromagnetic noise. Its compact form factor fits standard panel installations and supports straightforward integration into existing circuits. The Type D classification indicates suitability for protective stages where high-energy pulses may occur, while the interference filter helps maintain signal integrity for sensitive electronics.

Suitable for

• Protecting household electrical panels and appliances against transient overvoltages
• Shielding small commercial or office equipment from surges and EMI
• Use in installations where both surge suppression and reduction of electromagnetic interference are required

Key specifications

• Poles: 2-pole configuration for single-phase circuits
• Rated impulse withstand: 1 kV transient suppression capability
• Interference filter: triple-stage filter for EMI/RFI attenuation
• Application: intended for low-voltage residential and light-commercial panels
• Mounting: panel/rail-compatible compact design for electrical enclosures

How to use

Install the surge protector in the distribution board or dedicated panel according to local electrical regulations and the system wiring scheme. Connect the two poles to the live and neutral conductors of the protected circuit, ensuring secure terminals and proper grounding of the electrical enclosure. Verify that the device is positioned upstream of the loads to intercept transients and that any upstream protective devices are coordinated with the Type D surge protector. After installation, test the circuit to confirm normal operation of protected equipment.

Usage recommendations

Use the device as part of a layered protection strategy: combine with upstream main protection and downstream point-of-use protective devices where required. Ensure proper earthing and periodic visual inspection; replace the surge protector after severe surge events or if indicator functions (if present) show end-of-life.
