The CAD50P7TQ is a TeSys Deca auxiliary contactor — a control-circuit relay with 5 normally-open poles, intended for switching signal loads in motor starter or automation panels. The 6 kV impulse withstand confirms it can handle typical switching surges without flashover. It's rated for utilisation categories AC-15 and AC-14, so it switches electromagnetic loads (contactors, relays, solenoids) and resistive loads in control circuits. The mechanically linked contacts per IEC 60947-5-1 are a safety feature: if one NO welds shut, the others cannot close, which matters for safety circuits where you need to guarantee a break.
If you need a drop-in replacement for a new design, look at the current TeSys Deca range with the same pole count and coil voltage — but verify the mounting footprint and terminal layout against your panel cut-out, as form factors can shift between generations.
The 5 NO contact configuration is fixed — no convertible poles. If your circuit needs a normally-closed auxiliary, this block won't give you one without an external interposing relay. The control circuit voltage limits are: dropout at 0.3 to 0.6 Uc, and operational pick-up at 0.8 to 1.1 Uc at 50 Hz, or 0.85 to 1.1 Uc at 60 Hz. Ambient temperature range is -40 to 70 °C at rated coil voltage, narrowing to -5 to 60 °C if you run at the lower end of the voltage band (0.8 Uc). Storage range is -60 to 80 °C. The TH protective treatment per IEC 60068 means it's coated against humidity and condensation — fine for unheated enclosures in temperate climates. Vibration resistance: 2 gn at 5-300 Hz with contacts open, 4 gn with contacts closed. Shock: 10 gn open, 15 gn closed. That's typical for general industrial use but not for high-vibration environments like near a large press or crusher — if your panel is on a machine frame that sees repeated shock, you may need a dedicated vibration-rated block.
The CAD50P7TQ carries approvals to IEC 60947-5-1, EN 60947-5, VDE 0660, BS 4794, NF C 63-140, and IEC 60335-1. The UL and CSA certifications are noted on the insulation voltage rating, so it is accepted in North American panels as well as European. IP2X finger protection per VDE 0106 means the terminals are touch-safe when wired — no extra shrouding needed for basic protection.
