Mounts via screw or snap-on onto a standard 35 mm DIN rail — the S00 frame size keeps the footprint compact at 45 mm wide, 70 mm tall, and 73 mm deep. Side-by-side mounting is allowed, which is typical for a contactor relay bank. That matters when you're squeezing this into a railway cabinet with cable trays and other gear already in place.
Switching performance and ratings across voltages
The contactor relay is rated for a range of DC voltages beyond the typical 24 V and 230 V points: 4.7 A at 60 V, 3 A at 110 V, 1.2 A at 220 V, 3 A at 400 V, 2 A at 500 V, 1 A at 690 V, and 0.5 A at 440 V, plus 0.26 A at 600 V. That spread tells you the contacts are designed for moderate inductive loads across the railway voltage spectrum — not just one sweet spot. The arcing time sits between 10 and 15 ms, and the DC operate time is 25 to 45 ms.
Coil power and environmental limits
The DC magnet coil draws 4.5 W during closing and holds at 0.75 W — the holding power is low enough that a 24 V battery-backed supply won't be taxed across a bank of relays. Minimum relative humidity is 10 %, which is relevant for dry-climate or air-conditioned equipment rooms. The substance prohibition date of 2009-10-01 aligns with RoHS compliance — no lead or cadmium in the alloy.
