FAQs
Install the CM-PBE on DIN rail TH35-15 or TH35-7.5 with the device level. Use the screw terminals for static wiring: connect the measured L-L 380-440 V AC supply and the 1 n/o output to the controller. Tighten to 0.6–0.8 N·m and observe 10 mm wire stripping. This arrangement ensures reliable phase loss monitoring with minimal wiring effort.
Key specs include measuring range (L-L) 380-440 V AC, rated supply frequency 50/60 Hz, and output 1 normally open contact. Operational currents are 4 A at 230 V AC (AC-12) and 3 A at 230 V (AC-15). Startup delay is 500 ms, and tripping delay is 150 ms. Insulation voltage is 400 V, and impulse withstand is 4 kV for input circuits.
Yes. The CM-PBE is designed for phase failure detection in three-phase mains, making it ideal for protecting motors, conveyors, and pumps in automation environments. Its fixed threshold monitoring, robust DIN-rail mounting, and compatible 380-440 V AC networks help minimize nuisance trips while maintaining reliable protection.
The device carries UL 508, CE, and UKCA marks, along with RoHS compliance. Additional declarations cover CE EU conformity and UK declarations of conformity. These certifications support regulatory compliance in global facilities and streamline supplier audits and product qualification processes.
Expect reduced maintenance time due to clear fault signaling and fast response to phase loss, leading to less motor wear and downtime. The compact footprint and DIN-rail mounting simplify retrofits, lowering installation costs and enabling quicker commissioning. Long-term reliability lowers total cost of ownership for OEMs and maintenance teams.
