Size S00 frame, so it mates directly with S00 contactors like the 3RT2 series without extra bracketry. Mounts directly onto the contactor via the fastening method (contactor mounting), no DIN rail needed for the relay itself. The dimensions — 45 mm wide, 87 mm tall, 78 mm deep — keep it within the S00 envelope, and the IP20 front protection means it's safe for finger contact inside an enclosed panel. That zero-clearance spec simplifies panel layout — you can stack relays tight vertically.
Terminal details and wiring
Main circuit accepts solid conductors: 2x (0.5...1.5 mm²) and 2x (0.75...2.5 mm²), plus AWG equivalents 2x (20...16), 2x (18...14), and 2x 12. Auxiliary contacts take 2x (20...16) and 2x (18...14) AWG. Finely stranded with core end processing follows the same cross-sections. That covers the common panel wire sizes — no need for ferrule adapters unless your shop standard calls for them.
Rated for operation from -20 to +70 °C, storage and transport from -55 to +80 °C. 100 % relative humidity during operation — no derating needed for condensing environments. Shock resistance rated at 8g for 10 ms, which covers most industrial vibration profiles. Surge voltage resistance rated at 6 kV, giving solid margin for transient protection on 400 V line supplies. Carries ATEX approval (DMT 98 ATEX G 001) for use in potentially explosive gas atmospheres — the thermal model is certified for Ex e motor protection. The substance prohibitance date of 07/01/2006 aligns with RoHS compliance scope.
