E-T-A Power relays are reliable problem solvers when it comes to switching high currents. Particularly construction machinery, agricultural vehicles as well as buses and trucks, floor-borne vehicles and other special vehicles (e.g. fire brigades) often have connected large electrical loads. In these applications, power relays disconnect the entire on-board electrical system from the battery.
Depending on the application, E-T-A offers purely electro-mechanical relays, solid state relays and also a hybrid design consisting of an electro-mechanical switching system with an intelligent electronic control unit.

4770: Dual Block Outlet 16A
The demand for higher power density in data centers and industrial environments is constantly growing. Schurter is responding to this development with the new 4770 dual block outlet, which is designed for a rated current of 16 A and optimized specifically for use in power distribution units (PDUs). The 4770 combines a robust design with easy installation.
Thanks to its dual block configuration, the outlet can be integrated into power distribution units (PDUs) in a space-saving manner. The proven snap-in mounting system ensures quick and secure installation and reduces installation effort.
The 4770 outlet is available in black, gray, or white, offering flexible design options for different applications (multi-phase systems). Various connection options (standard: QC 6.3 mm; QC 4.8 mm; solder connections, and PCB mounting available on request) allow easy adaptation to different wiring concepts. VDE, UL, and CCC certifications ensure international compliance and a high level of safety and reliability.
The dual outlet is designed for currents of up to 16 A at 250 VAC according to IEC and 20 A at 250 VAC according to UL. It is designed for an operating temperature range of –25 °C to +70 °C. Installation is via snap-in mounting (standard: wall thicknesses 1.2 mm and 1.5 mm, 0.8 mm to 3.0 mm on request).
The 4770 dual outlet is ideal for use in data centers, industrial plants, IoT infrastructures, and IT as well as telecommunication systems. In other words, wherever compact and powerful power distribution is required.

MSM II-Switch with M12 Connector
With the new switch from the MSM II family with M12 connector (8 pins), Schurter is focusing on a solution that has been specially developed for demanding industrial and commercial applications. Thanks to the M12 connector system, robust construction, and integrated RGB illumination, this switch combines maximum reliability, functionality, and modern design in a compact unit.
The standardized M12 connector ensures fast, secure, and error-free installation—without any complicated wiring. Thanks to the fixed pin assignment, wiring errors are effectively avoided, which not only simplifies installation but also speeds it up considerably.
The mechanical design is made for permanent industrial use—shockproof, vibration-resistant, and resistant to tough environments. This means the switch will keep working reliably for years, even in extreme conditions.
The three-color RGB illumination provides clear status indication or individual signals. Example: green = active; red = off; flashing orange = error condition. This makes the switch ideal for machine controls, control systems, or user interfaces.
The new Schurter MSM II M12 switch is suitable for applications where installations must be made quickly, easily, and safely. It is used in industrial automation, machine and plant engineering, as well as in public and commercial areas where clear signaling and high reliability are required.
