This is the add-on block, not a standalone RCBO; it mates to the MCB via screw terminals and shares the same DIN-rail footprint. Clip-on mounting to DIN rail, 3-pole wide (54 mm width, 69 mm depth, 81 mm height). The 9 mm pitch matches standard modular DIN-rail accessories, so it fills four 9 mm module positions. That makes it suitable for general-purpose circuits with resistive, inductive, or electronic loads that don't generate DC fault currents. Voltage-independent tripping means the RCD operates without needing a separate power supply; it uses the fault current itself to trigger the mechanism.","metaTitle":"A9N21460 Vigi DT40 3P 25A 30mA Earth Leakage Add-on Block, O","metaDescription":"A9N21460 Prodis Vigi DT40 add-on residual current device, 3P, 25A, 30mA, Type AC.

For a drop-in replacement, you would need to cross-reference the panel's voltage, current (25 A), sensitivity (30 mA), pole count (3P), and Type AC earth-leakage class against current Schneider Prodis or Acti9 iID ranges — but that requires verifying the mechanical interface (screw-terminal add-on block vs. modular RCBO) and DIN-rail footprint."},{"question":"Where can I buy A9N21460?","answer":"The A9N21460 is sourced to order through independent distribution. Submit an RFQ for current availability and pricing — we search surplus and broker channels for working pulls or new-old-stock units."},{"question":"What compliance documentation does A9N21460 carry?","answer":"The part is certified to EN 61009-1 and EN 61009-2-1, with a rated impulse withstand voltage of 6 kV and pollution degree 3.
