E-T-A MPR20 Mechanical Power Relay

The Most Energy-Efficient Monostable Power Relay

The MPR20 is a monostable electro-mechanical high current relay. Its wide range input allows installation and operation in both 12V and 24V on-board electrical systems without change of the hardware and it carries 300A continuously. In the event of a power disruption, the relay will at once go into its original state due to its monostable design.

Reduction of holding power by 80% and of pull-in power by 50% allows direct connection to the controlgear and provides additional cost reduction and environmental advantages in spite of a monostable design. By using standard termination technologies and mounting dimensions, the MPR20 can easily and quickly replace conventional relays.

Benefits:
• Reduced fuel consumption and CO2 emission due to an 90% lower holding power
• Flexible installation for demanding applications due to a robust, water- and dust-proof design
• Reduced installation time through direct connection to the controlgear

E-T-A HVR10 High Voltage Power Relay – Hybrid and Powerful

The Most Powerful High Voltage Relay Up To 1000 V

 

The HVR10 is a hybrid powerful high end high voltage relay in a compact design. It combines physical isolation of high voltages via an electro-mechanical contact and state-of-the-art semi-conductor technology.

The hybrid, arc-free switching system allows reliable disconnection, even in the event of an overload, of up to 2 megawatts – 2,000 A/ 1,000 V. The HVR10 withstands high short circuit currents up to 5,000 A until the fast HV-fuse trips. The fist-sized unit can switch and permanently process 300 A at 900 V up to 50,000 times, arc-free and wear-free. The innovative self-monitoring function immediately signals critical operating conditions to the controlgear.

Features:
• Continuous current capacity of 300 A at 25 °C or 250 A at 85 °C.
• The rupture capacity of up to 2000 A at 1000 V is valid for both current directions without restrictions. It is therefore possible to lead even high charging currents over the relay.
• Very low current consumption in the ON condition of typically 0.2 W (12 V * 18 mA) due to a bistable drive, which only draws power from the supply when the switching status changes.
• For a short period of time, the HVR10 can carry up to 5000 A (25ms) and facilitates the co-ordination with a suitable HV fuse.
• The switching status of the mechanical contact system as well as the current rise upon switch-on operation is continuously monitored. This allows information of the control unit about critical operating conditions.
• The hybrid switching concept uses an electronic bypass that successfully suppresses the arc, thus significantly reducing the thermal load of the mechanical contact system.

Benefits:
• Reliable disconnection even in critical conditions up to 2,000 A at 1,000 V
• High protection of the on-board electrical system through integral fault detection and indication
• Long life span through low-arc switching operation

Applications:
• All utility vehicles, e.g. buses, trucks, construction machinery, specialty vehicles with electrical power train, mining vehicles etc.
• Voltages beyond the 450 V system voltage, charging stations, power storage and main relays in the vehicle

Standards:
• ISO 16750
• IATF 16949
• ECE R10

E-T-A Push-In Terminals for Circuit Breaker / Switch Combination 3120-N

E-T-A is the first manufacturer in the world to launch a circuit breaker/switch combination with push-in connection technology – the 3120 N…-PT. This design allows the quick, easy, and reliable connection of conductors. There are no tools required. The conductor can very easily be pushed in because of the special spring contour. This reduces wiring times and prevents fatigue symptoms.

The connection will withstand harsh shock and vibration conditions due to the high surface pressure of the contact spring that is made of a special spring steel. This type of connection is 100% protected against brush contact.
