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.

Intelligent lighting systems are key drivers for the rapidly growing global smart home sector. These not only have to be energy-efficient, sustainable, and cost-effective, but also connected for increased flexibility. Therefore, ZF decided to join the EnOcean Alliance in spring 2021 to join this growing market. This enables the expansion of ZF’s energy self-sufficient product portfolio with a wireless and battery-free light switch module with EnOcean3.0 protocol.

With its energy harvesting product range, ZF offers a sustainable alternative to traditional systems - based on radio and completely free of batteries and cables. ZF aims to promote this sustainable trend with new products especially for smart homes and the lighting sector. An essential step is to expand the light switch portfolio with commercially available protocols, to enable the switch to be integrated in commercial buildings. Beyond the unique energy harvesting KNX light switch module, ZF offers now a light switch module that can be fully integrated into existing EnOcean3.0 wireless systems. The EnOcean3.0 radio protocol is designed for a frequency band of 868MHz (EU, Asia) and 915MHz (USA). Within buildings, low frequencies are particularly suitable for penetrating walls or ceilings and ensure reliable radio transmission. In addition, the radio range is up to 30 meters inside the building. The wireless light switch modules from ZF are compatible with standard frames available on the market and can also be combined with customer-specific control and design panels.

In addition to light switch modules, customer-specific solutions can also be developed based on the EnOcean3.0 protocol for Smart Home applications. One example is connected doors and windows which transmit signals for ambient condition monitoring. Another application is for smart industrial switches and stop request buttons in buses which can transmit specific commands via RF to factory workers and bus drivers. The core component of these energy harvesting radio modules is a small generator (20.1 x 7.3 x 14.3 mm), which creates enough energy by means of induction and by pressing a button, so that a radio signal can be transmitted to a receiver. As a wireless solution, these radio modules offer flexibility and design freedom in order to accomplish individual requirements. As a battery-free solution and with a lifetime of up to 1,000,000 switching cycles, costly maintenance and disposal of replaced batteries can be avoided.

Crouzet HIH Relays monitor the stadium lighting electrical network current in order to alert the maintenance team as soon as a failure occurs.

The Olympic Committee defines strict standards for stadium lighting. The luminosity must be uniform on surfaces during the games to ensure an equity between athletes and an optimal quality of television broadcasting.

To ensure a top quality lighting of the event, the regulation imposes a maximum duration of 20 minutes between the breakdown and the repair of a stadium projector. That is why it is key to equip each stadium and playing field with a system checking the operating condition of the headlamps.

Features:
• Control of AC and DC currents
• Automatic recognition of AC/DC
• Measurement ranges from 2 mA to 10 A
• Choice between over and undercurrent
• True RMS measurement
• Selectable latching (memory) function

Easy Wiring with a New Plug-In Connector

The 3120-N thermal circuit breaker is a single pole or double pole device which can also serve as an ON/OFF switch. Based on its cost-saving design - two functions in a single unit - it has become an integral part of many applications in medical equipment and in apparatus and machine construction. Manufacturers of professional tools also like to use it because of its compact design.

As a new accessory E-T-A offers a plug-in connector for easily wiring the connecting cables.  Two retaining clips ensure a tight connection between the plug-in connector and the breaker. The dimensions of the female contacts (tab width 6.3) are in accordance with DIN 46340 part 3, shape A. E-T-A standard delivery scope is without female contacts.

Benefits:
• Reduction of wiring time during final installation saves time and costs - The plug-in connector can easily be pushed on without tools with a single movement. Female contacts do not have to be plugged on individually.
• Wiring errors are excluded during final assembly - The plug-and-socket connection follows the key-lock-key-principle so that the plug cannot be pushed in the wrong way round (fool-proof).
• Cable contact with long-term stability - The cable lugs latch irreversibly in the connector. The clamping arms of the connector ensure an extremely firm connection between circuit breaker and connector.
• Pre-wiring can be ordered externally - This allows you to use the know-how of specialised cable assemblers.
• Breakers can be swapped quickly and easily - The "old device" can be pulled out with a single movement. Then just push in the new device. Done!

Protecting and Switching in a Single Component

E-T-A’s 3120-N is a single pole or double pole thermal circuit breaker with a bimetal trip element that also serves as an ON/OFF switch. After tripping due to overcurrent, the 3120-N can easily, reliably and quickly be reset. Time-consuming replacement of fuses is eliminated. The 3120-N circuit breaker/switch combination helps you significantly reduce mounting and wiring time as well as expenses for material planning and stocking expenses.

The 3120-N rocker version is available as non-lighted or lighted (12 V - 400 V) and offers various actuator colours as well as marking choices. The 3120-N push button includes the traditional red/green option as well as a unique offering of protection from accidental operation.

                   With Rocker Actuation:                                                With Push Button Actuation:

* Add-on modules for undervoltage release, magnetic trip, remote trip and auxiliary contacts are also available. Appliance inlet modules, plug-in connectors, terminal adapters and a range of additional accessories guarantee solutions for your challenging applications.

Benefits:
• No fuse replacement required - After tripping due to overcurrent, the 3120-N can easily, reliably and quickly be reset.
• Reduced mounting and wiring time - You only mount one component. In addition, cables to connect switch and blade fuse are eliminated.
• Reduced planning and storage costs - 3120-N replaces a switch, a fuse-holder and blade fuses. This makes purchasing logistics much easier.
• Space-saving design - The 3120-N features space-saving integral overcurrent protection. This leaves room for creativity and ideas in terms of space design, even in constricted areas.
• Enhanced reliability - Less single components always mean: less sources of error. E-T-A’s 3120-N helps you consistently increase the overall reliability of your products.

Applications:
• Household, Hobby & Garden Equipment
• Industrial equipment control
