Eaton Corporation is offering a new plug-in unit for the NZM3 circuit-breaker. The NZM3 plug-in unit allows customers to exchange the circuit-breaker in a panel simply and quickly, and it also offers benefits during service work because the system section concerned can be disconnected simply and safely.

The housing design of the base has been adapted to that of the NZM3, so that all connection options provided by the main device can also be implemented in the base. For Eaton, safety has the highest priority, and the live parts in the base are therefore automatically protected from direct contact when the circuit-breaker compartment is pulled out. The circuit-breaker also disconnects automatically as soon as the mounting screws are loosened when the circuit-breaker is in the On position or when the circuit-breaker is pushed in. In the latter case, the circuit-breaker can then only be switched on if the mounting screws between the circuit-breaker and the plug-in unit base have been tightened.

Even with the wide range of features and capabilities provided by its products, simple operation and flexibility are top priorities for Eaton: Just fit the modified NZM3 with its rear terminal bolts into the guide, tighten the bolts, and the system is already operational. An auxiliary conductor plug-in device is also available as an option. This enables the connected shunt or undervoltage releases, auxiliary contactors and also the remote operator to be tested without having to fit the circuit-breaker into the panel.  In this way, correct operation can be tested prior to commissioning. Users also do not have to change the wiring when exchanging a circuit-breaker: The auxiliary conductor plug can simply be removed from its base, fitted onto the new terminal cables and operation is restored.

Technical specifications have been set to meet the wide range of requirements in the industrial sector and are impressive in every respect: The new plug-in unit on the NZM3 from 250 - 500A can be used without any derating up to an ambient temperature of 40°C, and this includes the extensive range of accessories. For more demanding applications, the full switching capacity of the NZM3 - up to 150kA at 415VAC - can be used. The circuit-breaker can also be fitted in many positions, either vertically or turned anticlockwise/clockwise by 90°.

FMCC SOL: 3-phase high-current filter
* Compact for highest performance
* 150 - 2500 A
* 520 or 760 VAC

Schurter is expanding its successful FMER SOL DC filter with a series for applications using 3-phase AC. The new FMCC SOL high-performance filter series is designed for rated currents from 150 to 2500 A. The devices are ideal for increasingly powerful inverters that require filters on both the AC and DC sides. Large inverters find use in photovoltaics, wind energy systems as well as in industrial applications and quick-charge stations for electric vehicles.

The very high-performance FMCC SOL 3-phase high-current filters are designed to handle currents from 150 to 2500 A at an ambient temperature of 50 °C. With a voltage rating of 520 V or 760 V, they can be used in all high-performance systems such as inverters for photovoltaic and wind power systems. Despite this high performance, they feature a compact, lightweight design.

The amount of renewable energy is constantly growing. As a result, ever more powerful and physically larger systems are being built such as for photovoltaics and harvesting wind energy. All these systems need high-performance inverters that are designed for optimal energy efficiency. Modern inverters with
MPP (maximum power point) trackers generate interference in both directions: on the AC grid side and the DC panel side. On the DC side, a filter in the FMER SOL series can be used for currents from 25 to 2300 A. These are enhanced very nicely on the AC side with the new FMCC SOL high-current series for
3-phase AC from 150 to 2500 A. Filtering on both sides of the connection lines helps to meet common EMC standards.

The FMCC SOL filter family has UL approvals for ambient temperatures of +50 °C as well as +40 °C with higher rated current. They are approved for voltage ratings of 520 VAC and 760 VAC. The high voltage rating of 760 VAC allows their use in IT power grids.

The FMC SOL up to 250 A is equipped standard with M10 screw connections and starting at 320 A with copper bars. Other connection types (stranded wire or copper bars for current levels less than 320 A) are available on request. In addition, customer modifications to the switching or the housing are also possible on request.

For optimal matching to the inverter, SCHURTER offers its own EMC measurement service. In this way,
the most efficient filter solution for a system can be easily determined.

Technical features:
- Rated voltage: 520 or 760 VAC
- Rated current: 150 A to 2500 A
- Connection versions 150 - 250 A: M10 screw connections
- Connection versions 320 - 2500 A: copper bars
- cURus approval: E72928

Bulgin – an Elektron Technology connectivity brand – has launched 4-, 6- and 8-pole versions of its popular PX0777 environmentally-sealed in-line cable joiner, offering cost-effective water- and dust-proofing for a wide range of applications.

 The original 3-pole version of the PX0777 has been part of the Bulgin Buccaneer range of environmentally sealed connectors for over 15 years, taking advantage of the Company’s tried and tested technology to provide convenient IP68 rated connectivity for indoor and outdoor use. The recently released 4-, 6- and 8-pole cable joiners extends this robust environmental protection to a wider range of applications, offering rapid connection of multi­core cables.

The new variants of the PX0777 uses a specially designed circular terminal block – rated at 10 A, 250 V per pole – allowing safe, secure connection of up to eight 1.5 mm2 cores using the same compact moulded plastic body as the 3-pole version. Available with a variety of sealing glands to suit 3.5 to 9 mm cables, the PX0777 can be quickly and conveniently assembled without the need for special tools, making it ideally suited to on-site installation of mains power or signal connections, either planned or unplanned.

Stuart Hutchings, Marketing Manager for Bulgin, commented: “The new PX0777 is designed for use across a broad range of demanding applications in harsh environments. Engineers often don’t know the exact length of cable needed until they get onto a site, so a ‘fit and forget’ solution such as the PX0777 is perfect for these situations, providing a reliable, long-term sealed connection in minutes.”

Zero Stand-by Power for Energy Savings

Johnson Electric today announced an extension to the TIPPMATIC® switch product line.  Three TIPPMATIC switches have been custom designed for use in all types of coffee machines.  The new TIPPMATIC pushbutton switches are configured with features for use in filter, capsule, espresso and fully automatic coffee machines. These pushbutton switches are compact and can be customized to match the human factors and design requirements of the coffee machine. 

In addition to the automatic power-off feature, the TIPPMATIC switch is available with a double disconnect feature which reduces the stand-by current of the coffee machine to zero.  This disconnect feature also further improves the safety characteristics of the machine. The TIPPMATIC pushbutton switches for coffee machines expand the existing rocker switch product line.

* TIPPMATIC Timer with an internal timer is designed for filter coffee. The switch can be configured for a wide range of automatic power-off times.
* TIPPMATIC iF has an interface for an externally provided shut-off signal, generated by the electronics in fully automatic coffee machines.
* TIPPMATIC iFD features a double disconnect technology with an integrated interface for an externally provided shut-off signal, generated by the electronics in fully automatic coffee machines.

“The cumulative impact of reducing stand-by power to zero is highly significant,” said Jim Dick, Johnson Electric’s senior vice president of Strategic Marketing. “Consumer peace of mind results by knowing that an appliance will automatically be switched-off in their absence,” he added.
