Product details

The Schneider Electric WB1JB342 is a low-consumption contactor coil from the TeSys range, designed to drive CV1B and CV3B contactors. It accepts a control circuit voltage of 380 V AC at 50 Hz or 440-450 V AC at 60 Hz, with operational limits of 0.85 to 1.1 Uc at those frequencies up to 55 °C.

Electrical Characteristics for Fit Verification

The coil draws an inrush power of 120-145 W (140-165 W at 60 Hz) and 700-840 VA at 50 Hz (915-1100 VA at 60 Hz). Hold-in consumption drops to 28-45 W (41-65 W at 60 Hz) and 80-110 VA at 50 Hz (115-170 VA at 60 Hz). Average resistance is 19.37 ohms at 20 °C, and the closed-circuit inductance is 4.1 H. Mechanical durability is rated at 1,200,000 cycles.

Frequently asked questions

What contactors does the WB1JB342 coil fit?
