USL relay sockets provide separate wiring connections for the coil and contact circuits of URL relays. USL-2E and USL-2P support the two-changeover configuration; USL-4E supports four changeover contacts. Choose the exact socket configuration before selecting the termination method. Relay bodies are separate products.
| Model | Relay configuration | Connection | Socket current rating | Socket voltage rating |
|---|---|---|---|---|
| USL-2E | 2 changeover contacts (2CO) | Screw, protected socket | 12A | 300VAC |
| USL-4E | 4 changeover contacts (4CO) | Screw, protected socket | 16A | 300VAC |
| USL-2P | 2 changeover contacts (2CO) | Push-in | 16A | 300VAC |
The socket rating is separate from the switching capacity of the fitted relay. Select the relay coil voltage and contact load rating for the actual circuit.
| Model | Conductor cross-section | Screw torque | Coil-to-contact withstand voltage | Between-contact withstand voltage |
|---|---|---|---|---|
| USL-2E | 0.5-2.5mm² | 1.0N·m | 2000V | 2000V |
| USL-4E | 0.5-2.5mm² | 1.0N·m | 2000V | 2000V |
| USL-2P | 0.25-2.5mm² | Not applicable | 4000V | 2500V |
The duration of the dielectric withstand tests is not specified.
| Model | Ambient temperature | Weight |
|---|---|---|
| USL-2E | -40°C to +65°C | 48g |
| USL-4E | -40°C to +65°C | 86g |
| USL-2P | -45°C to +85°C | 46g |
