Product Description

High-Performance Winston BMC7 2poles 4poles 16A 20A 25A 32A 40A 63A Household AC DC Contactor for Home AC Systems

The 16A-63A monopole contactor is an AC contactor with a width of only 18mm. The product uses M5 wiring screws with a maximum wiring capacity of 25mm2. The product uses hidden coil terminal design, with larger and safer electrical clearance
Higher current :

The product is only 18mm wide and has a maximum current of 63A 

Greater wiring capacity :
M5 cable screw, the maximum cable connection capacity is 25mm2 

safer :
Hidden coil terminals for greater and safer electrical clearance 

Two kinds of contacts :
The normally open and normally closed contacts are optional

Product Description

1. Ultra-Compact, High-Capacity Design
"An industry-leading slim profile of just 18mm, capable of handling high currents up to 63A."

The Proof: With a width of only 18mm and a maximum current rating of 63A, this contactor offers superior performance density. It saves crucial space in your electrical cabinet, allowing for more compact and efficient system designs than bulkier standard contactors.
2. Engineered for Extreme Longevity
"1 million mechanical operations and 100,000 electrical cycles ensure reliable performance for years to come."

The Proof: A mechanical life of 1,000,000 cycles and an electrical life of 100,000 cycles (at a maximum of 100 operations per day) mean this device is built to last far beyond the typical lifespan of home AC systems, providing outstanding value and reliability.
3. Enhanced Safety for People and Equipment
"Hidden coil terminals and high 2.5kV impulse protection create a safer operating environment."

The Proof: The innovative hidden coil terminal design prevents accidental contact, increasing electrical clearance. A rated impulse withstand voltage (Uimp) of 2.5kV protects the contactor and your valuable appliances from damaging voltage surges on the main power line.

4. Superior Thermal Management for Stable Performance
"Designed with mandatory cooling spacers to ensure stable operation and prevent overheating under full 63A load."

The Proof: The specification requires installation with spacers on both sides. This critical design feature promotes optimal heat dissipation, ensuring consistent performance and preventing premature failure even when operating at the maximum rated current.
5. Global Compatibility & Installation Flexibility
"Broad voltage compatibility (12-48V SELV to 250V AC) and 50/60Hz operation for versatile applications worldwide."

The Proof: The coil control circuit is compliant with SELV (Safety Extra-Low Voltage) standards (12/24/48V AC), while the main circuit is rated for 250V AC/50-60Hz. This makes it an incredibly flexible solution suitable for a wide range of control systems and geographic regions.
6. Optimized for High-Capacity Wiring
"Features M5 screws that accommodate large wires up to 25mm², ensuring secure and code-compliant connections for high-current circuits."

The Proof: The large M5 wiring terminals support cables with a cross-section of up to 25mm². This ensures you can make robust, reliable, and safe connections even for the highest 63A applications, meeting the demands of modern electrical installations.
