Sometimes it's easier to understand when you can see a product in action. Below you will find E-T-A's videos demonstrating it's latest innovations in circuit protection and relay technology.
The 3120 circuit breaker switch combination is a time and cost savings solution for equipment and machines. Well proven a million times over, the 3120 serves as an on off switch and also reliably disconnects over current. After tripping, the user can immediately reset the 3120 and resume operation.
The 3120 version with push in connection technology is globally unique. Thanks to consistently high spring forces at the terminal it ensures a permanently stable cable connection. The easy connect plug in connector reduces wiring time during assembly. It can be plugged on quickly without any tools.
E-T-A presents the next generation of the 3120 circuit breaker/switch combination. It's even easier and safer to operate, and offers significantly improved water and dust protection. The 3120 circuit breaker/switch combination is a time and cost saving solution for equipment and machines.
E-T-A's HVR10 is the most powerful high-voltage contactor in the market, with a compact design for electric vehicle applications. It combines physical isolation of high voltages via an electromechanical contact and state-of-the-art semiconductor technology. These high-voltage contactors are ideal for buses, trucks, construction machinery and specialty vehicles with electrified power trains, as well as charging stations and energy storage.
E-T-A power relays are ideal for switching high current loads up to 300 amps as well as battery management in buses, trucks, construction machinery, agricultural vehicles and forestry equipment and specialty vehicles. The power relays are made with high-end and corrosion-proof materials, making them extremely robust and able to withstand environmental factors like shock, vibration, water and dust.
For applications in harsh environmental conditions, E-T-A offers the 3120 circuit breaker switch combination with an integrated seal. The new seal is IP65 rated. Even fine dust or water jets will not damage or cause failure to the device or to the equipment where it's used.
The ESR10 micro is a compact and cutting edge automotive solid state relay. It's suitable for all vehicles, from passenger cars to utility vehicles, buses to construction machinery and agricultural vehicles. It's available at power levels up to 30 amperes, making it the most powerful ISO micro solid state relay on the market.
The 3120 with push-in terminal technology is the first of its kind. It allows effortless wiring without additional tools. Due to consistently high spring forces within the terminal, the push-in connection technology ensures secure contact of the conductor over an extended period of time. The connection will withstand harsh shock and vibration conditions due to the high surface pressure of the contact spring made of a special spring steel.
Electronic overcurrent protection in DC 24 volt applications provides fast detections and resolution of overcurrent and short circuits. This significantly increases productivity. Why are MCBs not able to trip reliably? MCBs with C characteristics only trip with at least 15 times rated current. Such a high current can not be provided by a switch mode power supply. Long cables and the resulting resistance values also limit the short circuit current.
Electronic DC 24 V circuit protectors help detect overcurrents and short circuits in your machinery faster. This significantly increases machine uptime. Switch-mode power supplies do not provide enough current to trip an MCB. Long cables, and the resulting resistance values are further impediments. Only electronic circuit protectors offer effective protection because their trip threshold is lower without tripping fast.
Permanent availability is a top priority in factory automation. For a reliable DC 24-volt protection, you need electronic overcurrent protection. It reliably detects overcurrent and short-circuits, and features a selectable trip limit. In the event of a failure, a switch mode power supply will not provide enough current to make conventional protective elements trip. Long cables and the resulting resistance values are further impediments.
