At 45 mm wide and 73 mm deep, it fits standard 45 mm slot spacing; side-by-side mounting is allowed with zero gap, so you can pack multiple units across a DIN rail without worrying about derating from heat buildup.
Ratings that matter for the buyer
The coil pulls 1.4 W both closing and holding — no extra inrush to size your 24 VDC supply around. Pick-up is at 85% of rated voltage (20.4 V), drop-out at 185% (44.4 V), so it stays latched through a saggy bus but drops cleanly on overvoltage. Main contact ratings: 10 A at 24 V (AC-12), 8.5 A at 400 V (AC-4), and 5.5 kW motor load at 500 V or 690 V (AC-3). For type 2 coordination, protect with a 20 A gL/gG fuse; type 1 allows 35 A. The built-in varistor surge suppressor handles coil transients, so you don't need an external snubber.
Spring-loaded terminals on the main circuit accept 2x (0.25 to 2.5 mm²) solid or stranded, or 2x (24 to 14 AWG). Strip length is 8 mm — standard for this terminal family. The terminals are IP20 rated, so finger-safe inside a panel.
