Siemens Industrial Controls 3RB3026-1QB0 Relay
As a veteran tech in the field, you know that keeping a motor running without unnecessary tripping is all about precision. The Siemens 3RB3026-1QB0 is an industrial-grade electronic overload relay from the SIRIUS series, specifically engineered for S0 size contactors. Unlike standard thermal units that rely on heater elements, this solid-state device uses integrated current transformers to monitor the 6A to 25A current range with high accuracy. This is critical for phase failure protection and unbalance protection, ensuring your three-phase motors are shielded from the heat-related failures that typically kill uptime.
The 3RB3026-1QB0 is a direct-mount solution designed to slide right onto 3RT202 contactors, simplifying panel wiring with its screw terminals for both the main and auxiliary circuits. It features a Class 10 tripping characteristic, making it ideal for standard motor starts where you need reliable protection against inverse-time delayed overloads. With a toggle for manual/automatic reset and a status indicator, this relay eliminates the guesswork during a fault condition. It is a solid, active stock item manufactured in the Czech Republic, meeting RoHS and REACH compliance for modern industrial standards.
Key Benefits
- Wide Adjustment Range: Covers 6A to 25A, allowing for precise 1:4 setting ratios to match motor nameplate data.
- Superior Protection: Built-in phase failure protection and unbalance detection perform better than mechanical alternatives.
- Reduced Power Loss: Solid-state design minimizes heat generation within the control panel.
- Size S0 Compatibility: Engineered for seamless integration with Siemens SIRIUS 3RT2023 through 3RT2028 contactors.
- Operational Versatility: Suitable for 50/60 Hz networks and compatible with frequency converter applications on the input side.
Common Questions
Can I use the 3RB3026-1QB0 for single-phase motor protection?
No, this electronic relay is specifically designed for three-phase motors and sinusoidal voltage networks. For single-phase applications, use a 3RU21 thermal relay.
What contactors will this relay mount to directly?
This relay is a Size S0 component, meaning it mounts directly to 3RT202 series contactors. It is not compatible with S00 or S2 frames without an individual mounting support.
Does it support remote resetting?
This specific model supports manual and automatic reset. If your application requires remote electrical reset, typically found in the 3RB31 series, you would need to check compatibility for integrated remote modules.
