For a panel builder, the 45 mm width and 78 mm depth let it sit in a standard 45 mm grid without crowding the adjacent device. Both the main current circuit and the auxiliary/control circuit use screw-type terminals. The solid and finely stranded with core end processing accept 2× (0.5 … 1.5 mm²) and 2× (0.75 … 2.5 mm²); the AWG equivalents for auxiliary contacts are 2× (20 … 16) and 2× (18 … 14). That covers the common control wiring sizes for a motor starter — 1.5 mm² for the coil circuit and 2.5 mm² for the power loop. The finger-safe touch protection (IP20 on the front) means the terminals are safe to work near with the panel door open, provided the wiring is properly seated. The relay operates from -20 to +70 °C and can be stored or transported from -55 to +80 °C. Relative humidity during operation can reach 100 %, so it is suitable for unconditioned indoor enclosures where condensation may occur. The substance prohibitance date of 07/01/2006 indicates RoHS compliance from that date. The ATEX type of protection DMT 98 ATEX G 001 means the relay itself is not an ignition source in a gas atmosphere — relevant if the enclosure sits in a Zone 2 area, though the motor circuit protection must still be assessed as a system.","metaTitle":"Siemens 3RU1116-1HB0-ZW98 SIRIUS Thermal Overload Relay, Siz","metaDescription":"Siemens 3RU1116-1HB0-ZW98 SIRIUS thermal overload relay, Size S00, Trip Class 10, 3-pole, 78 mm depth, screw terminals.
