AC-4 at 400 V is 8.5 A — that's the plugging/reversing/inching current limit, so if your application does frequent jogging, stay under 8.5 A per pole. The 24 V 50 Hz coil draws a holding current in the range of 0.8 to 1.1 VA at rated voltage. For type 2 coordination (no-weld under fault), the required upstream fuse is 25 A gL/gG; for type 1 coordination (allow weld but clear fault), it's 63 A gL/gG. That gives you selectivity headroom when sizing branch protection. ## Mounting and Integration — DIN Rail, Side-by-Side, No Derating Dimensions: 45 mm wide, 85 mm high, 91 mm deep — fits standard S0 footprint. Wire ranges: main contacts accept 2x (0.5...1.5 mm²), 2x (0.75...2.5 mm²), max 2x (0.75...4 mm²) solid; auxiliary contacts accept 2x (1...2.5 mm²), 2x (2.5...6 mm²), max 2x 10 mm² solid or stranded.
