MOREK PMX 2P Fuse Disconnector for 10x38 Fuses, 1000V DC, 32A, PV Installation with Signaling

The MOREK PMX 2P fuse disconnector is a specialized component engineered for the protection and isolation of photovoltaic systems. Designed to accommodate 10x38 mm cylindrical fuses, this 2-pole device provides a robust solution for DC circuits operating at up to 1000V and 32A. It incorporates a built-in signaling function that allows for real-time status monitoring, ensuring that operators can quickly identify blown fuses and maintain the integrity of solar power installations.

Advantages

This fuse disconnector offers high reliability and safety for demanding DC applications. Its compact 2-pole design facilitates efficient space utilization within electrical cabinets, while the integrated signaling mechanism significantly reduces downtime by providing immediate visual feedback on the fuse status. The construction is optimized for the specific electrical characteristics of PV systems, ensuring stable performance and secure circuit disconnection under load.

Suitable for

• Photovoltaic solar power systems
• DC electrical distribution panels
• Protection of string inverters
• Solar combiner boxes

When it may not be suitable

This device is specifically rated for DC applications and should not be used in AC circuits. It is also not intended for use with fuses outside the 10x38 mm size standard or for currents exceeding the 32A rating.

Key specifications

• Number of poles: 2
• Compatible fuse size: 10x38 mm
• Maximum voltage: 1000V DC
• Maximum current: 32A
• Integrated signaling: Yes

How to use

The disconnector should be mounted on a standard DIN rail within an appropriate electrical enclosure. Insert the compatible 10x38 mm DC fuses into the holders before closing the unit. Ensure all cable connections are tightened to the manufacturer's specified torque to prevent overheating. The signaling feature will activate automatically if a fuse blows, allowing for quick identification and replacement.

What to consider before purchase

• Verify that your system voltage does not exceed 1000V DC.
• Ensure the current rating of 32A is sufficient for your specific circuit requirements.
• Confirm that the enclosure provides adequate space for a 2-pole DIN rail mounted device.
• Check that you have the correct 10x38 mm fuses available for installation.

Usage recommendations

Always disconnect the power supply before performing maintenance or replacing fuses to ensure operator safety. Regularly inspect the signaling indicator to confirm the operational status of your PV system.
