Trip class CLASS 10, so it clears overloads fast enough for standard induction motors without nuisance tripping on starting inrush. Rated voltage 690 V. Integrated auxiliary switch delivers a \"Tripped\" signal — no separate contact block needed. Power dissipation 5.2 W per pole. In a densely packed panel that adds up, so plan for airflow if multiple relays cluster. Mounts directly on a contactor via the fastening method specified; panel-builder will appreciate the 55 mm width and 105 mm depth. Lifecycle stage is current — no obsolescence notice, no last-time-buy date. RoHS substance prohibition date 10/15/2014. Terminals: screw-type for the main circuit, accepts 2x (0.5…1.5 mm²) or 2x (0.75…2.5 mm²) solid or stranded. Pozidriv PZ2 screwdriver tip, shaft diameter 5–6 mm. Temperature compensation from –40 to +60 °C. Mount in any orientation – no derating for sideways install.","metaTitle":"Siemens 3RU2136-4HB0 SIRIUS thermal overload relay, Class 10","metaDescription":"Siemens 3RU2136-4HB0 thermal overload relay, Size S2, Class 10, 690V rated, integrated auxiliary switch.
