ABB 1TGE120020R0405

Product introduction

The ABB 1TGE120020R0405 is a robust 3-pole AC contactor designed for reliable switching of low-voltage electrical loads, primarily in motor control and power distribution systems. As part of ABB’s Tmax XT series, this contactor combines high-performance switching capabilities with compact design, making it a versatile choice for industrial and commercial applications.

Engineered to handle up to 95 A in AC-3 duty (400 V), the ABB 1TGE120020R0405 excels in controlling induction motors—from conveyor drives in manufacturing plants to pumps in water treatment facilities. Its integrated 1 NO (normally open) auxiliary contact simplifies interlocking with control circuits, while the 230 V AC coil ensures compatibility with standard industrial control systems. In automation setups, the ABB 1TGE120020R0405 acts as a critical switching component, translating control signals from PLCs or relays into safe, efficient motor operation, ensuring seamless process continuity.

Core advantages and technical highlights

High durability: The ABB 1TGE120020R0405 boasts an impressive mechanical durability of 10 million operations and 100,000 electrical operations in AC-3 duty, making it ideal for applications requiring frequent switching—such as packaging line conveyors that start/stop hundreds of times daily. Its silver-nickel contact material resists welding and erosion, even under high inrush currents, reducing maintenance needs in heavy-duty scenarios like compressor control.

Efficient energy use: With low coil power consumption (12 VA hold), the ABB 1TGE120020R0405 minimizes standby energy loss compared to older contactor models. In a facility with 50 such contactors, this translates to approximately 450 kWh annual energy savings—equivalent to reducing carbon emissions by 250 kg. The coil’s wide voltage tolerance (±15% of 230 V AC) ensures stable operation even in unstable power grids, common in rural industrial areas.

Compact and flexible installation: Measuring just 85 mm x 65 mm x 105 mm, the ABB 1TGE120020R0405 fits easily into crowded control cabinets, optimizing space in OEM machinery or retrofit projects. It supports both DIN rail and panel mounting, with tool-free terminals that speed up wiring—critical for reducing installation time in mass-produced equipment like HVAC units. The modular design also allows easy addition of auxiliary contact blocks (e.g., 1TGE120020R0405’s compatible 1SBL801010R1211) for expanded control logic.

Safety and reliability: Designed to IEC 60947-4-1 standards, the ABB 1TGE120020R0405 includes features like arc quenching chambers to suppress electrical arcs during switching, protecting adjacent components from damage. Its wide operating temperature range (-25°C to +60°C) ensures reliability in cold storage facilities or hot industrial environments, such as foundries. The contactor’s IP20 rating, when installed in an enclosure, prevents accidental contact with live parts, enhancing operator safety.

Typical application scenarios

In industrial manufacturing, the ABB 1TGE120020R0405 is widely used to control 3-phase induction motors in material handling systems. For example, in an automotive parts warehouse, it switches a 15 kW conveyor motor that transports pallets between storage racks. The contactor’s high electrical durability handles 500+ daily start/stop cycles, while its 1 NO auxiliary contact feeds status signals to a PLC, enabling remote monitoring of conveyor operation. During maintenance, the low inrush current (65 VA) prevents voltage dips in the warehouse’s electrical network.

Within commercial HVAC systems, the ABB 1TGE120020R0405 controls 7.5 kW air handling unit (AHU) motors. It integrates with building management systems (BMS) via its 230 V AC coil, activating the AHU when room temperature exceeds setpoints. The contactor’s ability to operate at -25°C ensures reliable startup in unheated rooftop units during winter, while its compact size fits into the AHU’s control panel alongside variable frequency drives and thermal overload relays.

Installation, commissioning and maintenance instructions

Installation preparation: Before installing the ABB 1TGE120020R0405, ensure the mounting surface (DIN rail or panel) is clean, flat, and rated to support 0.3 kg (contact weight). Disconnect all power sources and use lockout/tagout procedures to prevent accidental energization. Verify that the control voltage matches the coil’s 230 V AC rating—using a multimeter to check supply stability. Use torque tools set to 2.5 Nm for main terminals (copper conductors, 10-16 mm²) and 1.2 Nm for auxiliary contacts to ensure proper conductivity without damaging terminals.

Maintenance suggestions: Inspect the ABB 1TGE120020R0405 quarterly for signs of overheating (discolored housing) or contact wear. Clean dust from the arc chambers using compressed air (max 5 bar) to maintain arc quenching efficiency. Check auxiliary contact operation with a continuity tester—replace contacts if resistance exceeds 100 mΩ. For high-cycle applications (e.g., >500 operations/day), lubricate pivot points annually with silicone grease to extend mechanical life. When replacing the 1TGE120020R0405, use only ABB-approved spare parts to maintain safety certifications (e.g., UL, CE).
