FAQs
The device mounts easily on TH35 DIN rails (TH35-15 or TH35-7.5) and uses screwless push-in terminals for rapid wiring. It supports flexible conductors up to 1.5 mm² and 0.5 to 1.5 mm² ferrules. Wire stripping length is 8 mm. This combination minimizes wiring errors and speeds installation in control cabinets.
It monitors phase failure, phase sequence, and phase unbalance. The measuring range is (L-L) 160...300 V AC, with a 200 ms start-up delay and an ON-delay tripping range of 0 s or 0.1...30 s, allowing tailored protection against transient disturbances in motor circuits.
Yes. The two SPDT outputs enable signaling and interlocking for motor protection schemes, and the device’s voltage and frequency compatibility (50/60 Hz) supports diverse production line configurations. Its compact DIN-rail form factor helps maximize panel density while maintaining reliable protection.
This relay carries CE and UKCA declarations, UL/CSA recognition, and CAN/CSA compatibility. It is listed for relevant standards (IEC/EN 63000, IEC/EN 60255-27, and UL 508) and includes RoHS, REACH, and SCIP declarations to support global deployments in regulated environments.
The device reduces downtime by preventing phase-related trips and misdetections, lowers wiring and commissioning costs with Easy Connect terminals, and extends motor life through precise protection. In high-uptime environments, these gains translate to faster commissioning, less maintenance, and improved overall equipment effectiveness (OEE).
