BMF9-04 MATSUSHITA Power Thermal Relay

Review MATSUSHITA Green Power Thermal Relay New Old Stock

The Matsushita BMF9-04 FT-20 Power Thermal Relay is a versatile and reliable electronic component designed for controlling electrical circuits based on thermal conditions. This particular model is suitable for applications requiring a thermal relay with a 20A contact capacity.

The BMF9-04 FT-20 Power Thermal Relay is engineered with a high-performance bimetallic element that responds to temperature changes. When the temperature of the surrounding environment reaches the set point, the bimetallic element deflects, causing the contacts to separate or connect, thereby interrupting or completing the electrical circuit as needed.

This Matsushita thermal relay is designed with a robust construction that ensures long-lasting performance. It features a compact size of 48.5 mm x 32.5 mm x 19.5 mm (L x W x H), making it an excellent choice for space-constrained applications. It is also compatible with a wide operating temperature range of -25 C to 85 C, allowing it to perform effectively in various environments.

The BMF9-04 FT-20 Power Thermal Relay also boasts excellent electrical specifications. It offers a contact rating of 20A at 250VAC and 10A at 600VAC, ensuring it can handle the electrical loads required by many applications. The relay features a low contact resistance of 0.1 at 25 C, ensuring efficient power transfer and minimal voltage drop. Additionally, it has a low coil resistance of 2.8 , which results in fast response times.

The Matsushita BMF9-04 FT-20 Power Thermal Relay is a low-maintenance component that provides reliable performance over extended periods. It is manufactured using high-quality materials and undergoes rigorous testing to ensure it meets the highest standards of quality and reliability. This thermal relay is an excellent choice for applications in industries such as HVAC, power generation, and automotive, where precise temperature control is essential.
