The Schneider Electric TeSys B CV1BJ2J0ZMD22 is a 2-pole power contactor rated for 470 A in AC-3 duty at 690 V AC, with a 220 V DC control coil. The AC-1 rating covers resistive loads like heating elements, where the current is lower-stress on the contacts. The 220 V DC coil has an operational range of 0.85 to 1.1 Uc (187 to 242 V DC) and drops out between 0.1 and 0.65 Uc (22 to 143 V DC) at 55 °C. That dropout margin is generous — it stays pulled in through a significant dip, but drops reliably when the control signal is removed. The coil is DC, so verify polarity and free-wheel diode placement if you're wiring it into an existing AC-coil panel.
Rated insulation voltage (Ui) is 690 V, matching the operational voltage — no derating needed for standard 400/480 V systems, and it handles 690 V line-to-line without issue. The 2-pole configuration with 2 NO main poles is typical for single-phase or DC switching, or for three-phase motor circuits where a third pole is handled externally. The auxiliary contact block is built in: 2 NO + 2 NC instantaneous contacts, which covers feedback and interlocking without an add-on block. That's a fast cycling rate — suitable for applications like conveyor indexing or press feeders where the contactor opens and closes frequently. The vibration resistance of 4 gn (2 gn in some axes) and shock resistance of 4 gn / 2 gn mean it holds up on machinery that sees moderate mechanical shock, but it's not rated for extreme impact environments. Maximum operating altitude is 2000 m without derating.
The contactor is certified to EN 60947-4 and IEC 60947-4, which covers the full scope of low-voltage switchgear and controlgear for motor starting and switching. These standards define the AC-1 and AC-3 ratings, the insulation voltage, and the operational performance. The part is classified under Schneider's 18402-WORLD SERVICE PARTS (CONTROL ACCESS) category, which is their internal service-parts coding for control components.
