The CAD326BL is a TeSys Deca control relay from Schneider Electric, designed for control-circuit switching in industrial panels. It carries 3 normally-open and 2 normally-closed poles, rated for operational voltages from 0 to 690 V with a 24 VDC low-consumption coil.
Rated for utilisation categories AC-14, AC-15, and DC-13 per EN/IEC 60947-5-1. AC-15 covers solenoid-valve and contactor-coil loads — the most common control-circuit duty — so this relay handles the inrush from pilot devices without contact welding. DC-13 covers solenoid loads with significant inductance, so it can switch DC coils reliably. The 24 VDC low-consumption coil draws less current than a standard DC coil, reducing heat in a crowded panel and easing the burden on a 24 VDC power supply shared across multiple relays. Mechanical robustness is specified to 10 Gn shock (11 ms) with the relay open and 15 Gn closed, plus vibration tolerance of 2 Gn (open) and 4 Gn (closed) across 5–300 Hz. That means it stays latched on a conveyor line or compressor skid without nuisance dropouts.
TeSys Deca control relays are the standard interface between a PLC or safety module and the power contactors in motor control centres and distribution panels.
The CAD326BL carries approvals under EN/IEC 60947-5-1, GB/T 14048.5, UL 60947-5-1, CSA C22.2 No 60947-5-1, and JIS C8201-5-1. That means it meets the control-circuit switching standard across North American, European, Chinese, and Japanese jurisdictions — no separate UL/CSA part needed for a global panel build.
