Siemens 3RB2036-2UB0 Solid State Overload Relay

Product Description

The SIEMENS 3RB2036-2UB0 is a solid state overload relay designed to provide motor protection in industrial control applications. Solid state overload relays monitor motor current electronically, offering more precise and repeatable trip characteristics than traditional bimetallic devices. This relay is installed in motor starter assemblies and motor control centers to protect three-phase motors from overload, phase loss, and phase imbalance conditions. Electrical contractors and industrial maintenance technicians are the typical installers for this class of device.

The 3RB2036-2UB0 is suited for use in motor control panels, automation cabinets, and industrial drive systems where reliable overload protection is required. It is appropriate for both new installations and replacement service in commercial and light industrial environments where solid state protection is specified over thermal-bimetallic alternatives.

Key Features

• Solid state overload protection provides consistent and repeatable trip response
• Suitable for three-phase motor protection applications
• Compact form factor fits standard motor starter and control panel configurations
• Electronic current monitoring reduces nuisance trips compared to bimetallic designs
• Designed for integration into motor control centers and starter assemblies

Compatibility

Designed as an OEM-style solid state overload relay for use in industrial motor control and starter assemblies. No specific compatible model numbers were provided in the available product data.

Installation Notes

Installation should be performed by a qualified electrician or industrial controls technician in accordance with applicable NEC requirements and local codes. Disconnect and lock out all power to the motor control panel before removing or installing the relay. Verify current range settings are appropriate for the connected motor nameplate full-load amperage before energizing. Do not exceed the relay rated voltage or current capacity for the connected load.
