DC-operated control relay for 36 VDC circuits
The CAD326CDS135 is a DC-operated control relay from the Schneider Electric TeSys series, built for switching loads in 36 VDC control circuits — not a standard AC contactor. The 36 VDC coil voltage is narrow-band; if your BOM calls for 24 VDC or 48 VDC, this part won't pull in reliably. Contact configuration is 3 normally-open and 2 normally-closed (3NO-2NC), giving 5 poles total. That arrangement is common for interlocking two contactors or building a reversing starter where the NC poles block simultaneous closure. Rated 10 A at 600 VAC but only 2.5 A at 600 VDC — the DC rating is the real limit for breaking inductive DC loads like brake coils or DC valve solenoids. The AC rating handles motor control circuit loads within its category.
Panel fit and field wiring
The IP2X open enclosure means it's finger-safe against accidental contact but not sealed against dust or moisture; install inside a cabinet, not in a washdown zone. Terminals are ring tongue type — field wiring needs ring lugs crimped onto the conductors. Fork or quick-connect terminals won't fit the screw clamp. This is a detail that trips up a first-time swap if the maintenance kit only has spade terminals.
Approvals and applicable standards
Carries UL, CSA, and CE approvals — accepted for panels destined for North America and the European market. The applicable standards include IEC 60947-5-1 and EN 60947-5, which cover control circuit devices, not power contactors. That means it's tested for the switching duty and endurance expected in a PLC output or relay interface circuit.
