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.","metaTitle":"Siemens 3RU1116-0HB0-ZX95 SIRIUS Thermal Overload Relay, CLA","metaDescription":"Siemens SIRIUS 3RU1116-0HB0-ZX95 thermal overload relay, CLASS 10, size S00, 45x87x78 mm, IP20, ATEX, screw terminals.
