3RB2036-1QB0 Siemens SIRIUS Solid-State Overload Relay, 6-25A Class 10 Size S2

The 3RB2036-1QB0 is a Siemens SIRIUS 3RB20 solid-state overload relay rated for an adjustable 6...25 A setting range, Class 10 trip characteristic, and Size S2 direct contactor mounting. It is IEC rated for the protection of three-phase motors on 50/60 Hz voltage networks, providing inverse-time-delayed overload protection along with phase failure and phase asymmetry protection for the load feeder.

At Essential Parts, we offer fast shipping, lowest price, and expert support to help you get the right product every time.

The relay mounts directly, in any position, to Siemens SIRIUS S2 contactors 3RT1033, 3RT1034, 3RT1035, and 3RT1036, with screw terminals on the main and auxiliary circuits. It is rated 690 V AC insulation voltage at pollution degree 3, with a 6 kV impulse withstand rating and IP20 protection on the front.

Common Applications

• Overload protection for three-phase motors on 50/60 Hz supply networks
• Phase failure and phase asymmetry (current imbalance) protection for motor branch circuits
• Direct-mount motor starter assemblies built on SIRIUS S2 contactors 3RT1033 through 3RT1036

Key Features

• Adjustable Current Setting: Dial-adjustable trip range of 6 to 25 A covers multiple full-load current settings with one relay.
• Manual/Automatic Reset: Reset mode is field-selectable after a trip event.
• Switch Position Indicator: Visual indication of relay trip status at the device.
• TEST Function and Self-Monitoring: Built-in test function with self-monitoring circuitry for maintenance checks.
