Main Features

1. Dual Contact Architecture: For minimal wear and extended life of the electrical system in high current disconnections, we have separate main and arc-breaking contacts.
2. Better Thermal Dissipation: Engineered with quality internal busbars and connections to securely handle continuous 2500A loads in compact enclosure designs.
3. Customizable Trip Unit: Seamlessly integrates with advanced electronic protection releases for accurate coordination of overcurrent, selective short-circuit, and ground-fault protection.
4. Marine-Grade Durability : Built to withstand persistent vibration, high ambient temperatures and humid situations, a key component of offshore applications.

Maintenance Guide from NDMarineTech:

1. Arc Chute Inspection: During annual black-out testing always draw the arc chutes. Check for carbon tracking or structural cracks. If the breaker tripped on a high load short circuit, replace the arc chamber sets promptly to ensure proper arc extinction in the future.
2. Note: Greasing Lubrication Only use the manufacturers prescribed lubricant (e.g. 5RX Moly Grease) on the mechanical functioning linkages. Do not use generic penetrating oils on the spring-charging mechanism as these will wash away the original grease and attract ambient dust, causing mechanical blockages.
3. Secondary Injection Testing: Always perform a secondary injection test on the integrated electronic release for reconditioned or surplus stock being put back into active service. This ensures that the time-delay characteristics are consistent with the selective coordination study for your vessel prior to tying it to the main bus.
