PLS6-DC xPole Miniature Circuit Breaker

Moeller pls6dc1

The PLS6 miniature circuit breaker (MCB) is a protective device that’s equipped with both a thermal and an electromagnetic release. The former responds in the event of an overload, while the latter offers protection against short circuits. The 1- and 2-pole PLS6 devices for DC applications are available with rated currents from 1 A to 50 A and can withstand rated voltages of up to 250 V DC. The switching capacity is 10 kA. The PLS6 is busbar compatible, and double life/claw terminals are available at the top as well as at the bottom for easy mounting.

Schurter Industrial Automation - Reliable Components and HMI

Reliable Systems Thanks to Schurter Components and HMI for Industrial Automation

Regardless of the industry, modern electronic systems place high demands on even the smallest components. Stability, durability and absolute reliability are basic requirements to ensure that processes run safely and economically.

Schurter automamtion hmi1

In automated systems in particular, a single fault-prone component can halt entire production processes. It is therefore worth taking a close look when selecting electronic components and HMI solutions.

Schurter offers robust, industry-compliant components that have been specially developed for demanding applications – with a focus on quality, functionality and durability. Industrial automation leverages machines, sensors, control systems, and software to enhance efficiency, precision, and productivity in industrial processes.

Schhurter products contribute to this by providing reliable power supply, robust protection, and seamless connectivity, ensuring smooth and uninterrupted operation. By minimizing manual interventions and optimizing production workflows, Schurter helps manufacturers achieve higher performance, increased uptime, and improved operational safety.

Below are some key aspects of this application:

Electronic Switch with IO-Link Interface
With the MSS-IO, Schurter is entering the field of bidirectional communication via switches in industrial automation. The MSS-IO is based on the successful SCHURTER MSS electronic switch, which has been expanded to include an IO-Link module.

Energy Harvesting for Wireless Sensors
Modern automated production equipment relies on numerous cables for power and data transmission. But cabling takes up valuable space, reduces accessibility, and is sometimes the most failure-prone part of a machine. This is where compact and powerful prismatic supercapacitors come into play.

By enabling sensors to operate independently of a fixed power supply, supercapacitors help reduce wiring complexity. A small energy source—such as a solar cell or a kinematic energy harvester—generates low levels of power, which are insufficient for directly operating the sensor and its control IoT module. Instead, this energy is stored in the supercapacitor. When needed, the supercap releases high-power pulses, providing enough energy for the sensor to take a measurement and for the IoT module to transmit data via Wi-Fi.

Particularily Slim: FPAC Rail EMC Filters for Machine Control Units
Space is almost always at a premium in control cabinets for industrial applications. SCHURTER addresses this problem with a complete new filter design that is just 44 mm in width. The new, single-stage filter series is constructed with a printed circuit board in a plastic housing. It has screw terminals for the three phases and a terminal on the metal base plate for the earth connection.

The New Schurter 6080 With Cordset
Protection against dirt particles and moisture is becoming increasingly important. With the product type 6080 and the associated V-Lock power cable, SCHURTER is launching an IP54 device connection that also meets very high demands.
