E-T-A Power Relays

E-T-A Power relays are reliable problem solvers when it comes to switching high currents. Particularly construction machinery, agricultural vehicles as well as buses and trucks, floor-borne vehicles and other special vehicles (e.g. fire brigades) often have connected large electrical loads. In these applications, power relays disconnect the entire on-board electrical system from the battery.

Depending on the application, E-T-A offers purely electro-mechanical relays, solid state relays and also a hybrid design consisting of an electro-mechanical switching system with an intelligent electronic control unit.

Key Product Lines & Features

• EPR10 Solid-State Relays: Designed for high continuous currents (up to 200A at 24VDC), requiring 80% less space than traditional alternatives and
  eliminating the need for separate heat sinks
• HPR10 Hybrid Relays: Combine robust mechanical, bistable switching with intelligent electronic controls, enabling features like on/off delays and voltage
  monitoring
• MPR10/MPR20 Mechanical Relays: Bistable (MPR10) or monostable (MPR20) relays designed for high current switching with low power consumption

Key Advantages

• Efficiency: Very low holding current reduces power consumption.
• Durability: High resistance to environmental factors (IP57 rated for some models).
• Maintenance: Long service life with reduced maintenance costs due to solid-state technology.
• Functionality: Options for built-in overcurrent, short-circuit, and thermal load protection.

Applications

• Battery Management
• Power Distribution
• Circuit Protection in Harsh High-Load Environments
