Siemens is expanding its generator circuit-breaker portfolio with a new compact version – the HB1-Compact (HB1-C). The versatile and highly customizable solution uses maintenance-free vacuum switching technology and addresses the most challenging of constraints. Available in L-shape and I-shape designs, the HB1-C can be mounted either vertically or horizontally and can be adjusted to match existing busbar connection points.
Siemens is the first company to successfully receive UL listing for a 120-volt, single pole solid-state circuit breaker. The solid-state breaker concept replaces the traditional moving parts of an electromechanical circuit breaker with semiconductors and advanced software algorithms that control the power and can interrupt extreme currents faster than ever before.
Littelfuse, Inc. has recently announced their new SMTOAK2 TVS Diode Series. Many of today’s high-power, high-surge-rating TVS diodes are only available in axial leaded packages. The compact, 2 kA 8/20 μs rated, surface-mount package SMTOAK2 TVS Diode Series allows electronics designers to achieve a more robust transient voltage, overvoltage protection, and lightning protection system while using less printed circuit board (PCB) space.
ABB’s OVR RS485Q & SL RS485 Series of Surge Protective Devices make surge protection easy for data and signal applications. These UL 497B listed SPDs are specifically designed for RS 485 and Fieldbus applications, such as Profibus DP for protection against the damaging effects of surges caused by lightning, electrical surges, and more on data and signal lines.
AutomationDirect has added more intrinsically safe isolation barriers from STAHL. These modules ensure only a safe amount of energy resides in an electrical circuit, installed in a potentially explosive atmosphere, so that no sources of ignition are created. More digital, analog, and temperature modules, new frequency transmitter isolators, and a Zener Barrier for thermocouple signals have been added.
Introducing the B1E Series miniature supplementary protectors from NOARK. NOARK’s Electric B1E Series miniature supplementary protectors are available in a complete range of amperages from 1A to 125A. Standard ratings of 5 kA at 480Y/277 Vac and 10 kA at 240 Vac. UL1077 listed and CSA C22.2 No.235 certified, these breakers are suitable for supplementary protection only. 5-Year limited warranty.
The Panel Extension PX3 from ABB protects and prevents costly downtime and equipment failure. PX3 features an externally mounted surge solution that can be physically attached to the top or bottom of any panelboard providing a reduced profile surge solution. Moreover, PX3 offers an internal disconnect option, allowing safer and easier repairs without having to cut power to the distribution panel.
Panduit Corp. has added to its SmartZone offerings with the release of the SmartZone Lithium Ion UPS, a highly efficient and reliable UPS that provides protection and backup power to meet the continually growing power demands of Data Center, Enterprise, and Edge IT equipment. The Lithium Ion UPS boasts excellent electrical performance, enhanced intelligent monitoring and network functions while complying with EMC and safety standards.
Emerson has introduced the SolaHD SSW Mini-Tower Line-Interactive UPS, a highly economical choice for preventing costly damage to IT and industrial automation devices from electrical surges, spikes, lightning strikes and blackouts. Available in capacities from 700VA to 1440VA, the SolaHD SSW ensures optimum waveform for equipment stability and longevity with its battery sinewave output.
With power, comes great responsibility. A panel builder who can effectively integrate ground-fault circuit interrupters (GFCIs) into a system can make the difference between life and death. Ground-fault circuit protection is one of the most effective preventative measures against electrical shock because it actively reacts to irregular electrical conditions, regardless of a worker’s qualifications or use of personal protective equipment (PPE).
Littelfuse, Inc. has launched its Energy Storage Rack (ESR) series of fuses designed specifically to protect battery racks from a range of fault currents to help prevent equipment damage and expensive system failures. The 1500V direct current (DC) high-speed square body fuse is extremely fast-acting to respond quickly, safeguarding the battery module or other devices in energy storage, power conversion, and DC common bus systems as well as hybrid photovoltaic battery energy storage system (PV-BESS) inverters.
Panel Extension PX3 protects and prevents costly downtime and equipment failure. PX3 features an externally mounted surge solution that can be physically attached to the top or bottom of any panelboard providing a reduced profile surge solution.

Two product versions have been added to Phoenix Contact’s portfolio of narrow surge protective devices for MCR technology with an overall width of just 6 mm. With TTC-6P-2×2 and TTC-6P-4×1, items are now available for protecting both analog and digital 4-conductor applications. Both product versions feature a modular design. They consist of a base element and protective plug, and have an integrated disconnect device.
The FLASHTRAB-MB surge protective device from Phoenix Contact is based on innovative carbon spark gap technology and meets high lightning protection requirements. The new FLT-MB-T1-264/12.5…UT-R surge protective devices are available in three different circuit versions. They are therefore suitable for use in 1-phase TN-S or TT systems as well as in 3-phase TN-C, TN-S, or TT systems.
TTI, Inc. is stocking the Vishay RER Military, High-Reliability, Chassis-Mount Wirewound Resistor. Qualified to MIL-PRF-39009 and up to “R” level failure rate, the aluminum-housed (ERH) standard or the non-inductive (ENH) winding/molded construction gives complete environmental protection. The RER, high-reliability resistor mounts on chassis for high stability at conventional power ratings.
Increase performance and save space with Weidmuller’s Hydraulic Magnetic miniature circuit breakers. The new universal-voltage HB-SERIES Circuit Breaker from Weidmuller is the latest addition to their Hydraulic Magnetic Circuit Breakers lineup. It features modularity, ease of use, and space-saving well beyond that of conventional circuit breakers.
