The main contact is made of copper alloy. Under a current of 200A, the contact resistance is less than 1mΩ, resulting in less heat generation and higher efficiency during long-term operation. The NVR6V-200D DC relay supports a continuous current of 200A and has short-term overload capability - it can handle 900A for 20 seconds, which is crucial for systems that need to cope with instantaneous current surges.
When tested under resistive load conditions, the NVR6V-200D can achieve:
- 50,000 times, 14.5V / 150A connection
- 10,000 times, 450V / 200A connection
- 500 times, 800V / 200A disconnection
Such a lifespan level makes it highly suitable for scenarios that require frequent switching, such as battery group on-off control and inverter DC bus management.
Rated operating temperature: -40℃ to +85℃. This NVR6V-200D DC relay can operate stably in both cold storage environments and photovoltaic stations exposed to direct sunlight. The internal design adopts a gas-sealed structure, which effectively protects the contacts from oxidation and contamination, thereby extending their service life.
The entire machine weighs only 250 grams, making it a lightweight contender in the same category of products. Using the vertical installation orientation, there are no polarity requirements for the coil ends of the load terminal box, which simplifies the wiring process and reduces the risk of incorrect installation.
The insulation resistance between the disconnected contacts exceeds 1000 MΩ, the dielectric withstand voltage reaches 3000 V a.c., and the isolation protection is reliable. It can withstand a mechanical impact of 50G and random vibration of 5G (ranging from 10 to 500Hz), and is suitable for vehicle-mounted and mobile applications.
