FCL Components America has introduced the FTR-E1J 20A, a tab terminal-type high voltage DC switching relay built on the proven FTR-E1 series. Unlike PCB-mounted relays, this model is screw-mounted, offering flexibility for applications where printed circuit boards are not used.

Performance and Capabilities

• Handles 20A at 800 VDC and 10A at 1,000 VDC, supporting higher voltage switching requirements.
• Features non-polarized contacts, eliminating polarity restrictions for load terminal connections.
• Operates with low coil power consumption of just 0.9W at rated voltage.
• Incorporates arc suppression technology to protect contacts during charge and discharge cycles.

Design and Reliability

• Compact dimensions: 28.3 x 43.6 x 36.1 mm (excluding protrusions).
• Lightweight at approximately 85g.
• High insulation design: 5,000 VDC between coil and contacts, 2,500 VDC between open contacts.
• Plastic-sealed construction ensures durability and environmental protection.
• RoHS compliant and designed without hydrogen gas for safer operation.

Applications
The FTR-E1J 20A is engineered for demanding environments across multiple industries:

• Automotive: EV, HEV, PHEV, FCV pre-charge circuits, quick charge stations, and PTC heaters.
• Energy: Photovoltaic power generation systems, V2H (vehicle-to-home) systems, and battery storage.
• Industrial: Hybrid construction machinery and other high-voltage equipment.

Benefits

• Simplifies integration with screw-mount design.
• Provides reliable switching for high-voltage DC circuits.
• Enhances safety and longevity with arc suppression and high insulation.
• Offers versatility across fuel, electric vehicle, solar, and battery applications.
