These photovoltaic (PV) array protection fuses feature ratings from 8A to 15A at 1,000VDC. The PV fuses also comply with the “gR” operating class and are manufactured to meet global standards of the 10-mm × 38-mm fuse package for coordination with 4-in., 5-in., and 6-in. solar cell panels. Tested and approved to IEC 60269, they provide full-range protection with minimum interrupting ratings down to 1.3 × In.
The FirstLine 924 is a 3-phase UPS central emergency lighting system designed for 8kW to 16kW applications. In addition to providing a continuous 90-min power supply during blackouts, the UPS isolates and protects the connected load from sags, swells, harmonics, noise, and voltage imbalances in the primary AC supply. The product's 3-phase operation supports 3-phase or single-phase loads.

These UL-listed 600VAC CP cable limiters are for cable sizes 2 AWG to 1,000 kcmil. Composed of fiberglass bodies, the devices also feature optional molded rubber boots and heat-shrinkable tubing for insulation and waterproof protection to the limiter body and terminations. Safely interrupting faults up to 200kA, they are available in seven terminal variations, including tube (cable crimp), offset blade (bolt-on), and compression rod terminations.
According to the company, these two 8kVA SmartOnline hot-swappable modular UPS systems include a corded input that eliminates the need for an electrician to install the UPS via hardwire connection. Model SU8000RT3UN50 features 200V to 240V input/output, and model SU8000RT3UN50TF includes a transformer module for additional 120V output. Both versions include a 50A Hubbell twist-lock plug and heavy-duty input power cord. Other features include expandable runtime, cost-reducing user-service options, flexible outlet configurations, remote management capability, and N+1 configurability for efficient fault tolerance.
The STFE Elite Series of Active Tracking filters is designed to be mounted on standard DIN rails. Product features include a metal mount clip, UL-listed surge current capacity of 45,000A, a fully enclosed metal housing, transient protection in all modes (L-N, L-G, and N-G), an operating temperature range of -40°C to +50°C, LED status indication, and a Form C contact for remote monitoring. Measuring 4.88 in. × 2.56 in. × 4.56 in., it is available in hardwire DIN rail-mount, single-phase configurations.
ECOsine T load-applied passive harmonic filters are for 3-phase power electronics with 6-pulse rectifier front ends, such as AC and DC motor drives. Due to the significant reduction in total harmonic current distortion to less than 5%, the company says the filters guarantee compliance with IEEE standard 519. UL-listed, CE-marked, and RoHS-compliant, the filters can be installed inside the electrical cabinet next to the drive. In addition, their standard safety feature continuously monitors filter temperature, controls the internal fans, and provides an NC/C contact.
