Product details

The Schneider TeSys WB1JB317 is a low-consumption contactor coil rated for 48 V AC at 50 Hz, intended as a service part for CV1B and CV3B contactors in the TeSys range. Its inrush power draw is 120...145 W (700...840 VA at 50 Hz), dropping to a hold-in consumption of 28...45 W (80...110 VA at 50 Hz) once the contactor seals in. The coil resistance measures 0.3 ohm, and closed-circuit inductance is 0.065 H. The control voltage limits are 0.85...1.1 Uc at 50 Hz (operational range at up to 55 °C).

Fit and Integration Notes

The low-consumption coil design reduces thermal load inside the enclosure compared to standard AC coils, which matters when multiple contactors are ganged in a confined panel.

Frequently asked questions

What is the closest alternative to the WB1JB317?

No direct successor or pin-compatible alternative is listed in the available records. For a form-fit-function equivalent, the replacement would need to be a 48 V AC 50 Hz contactor coil in the TeSys range designed for the same contactor frame (CV1B/CV3B), but no specific order code is confirmed.

How can I source the WB1JB317 now that it is obsolete?

We can source it through the surplus and broker channel. Submit an RFQ with your target quantity and lead-time requirement — we will quote from available open-market inventory.
