Description

Product Overview

The Fancat 24 V 225 A heavy‑duty solenoid relay is built to meet the exact specifications of the original Trombetta 114‑2411‑020 unit, providing a reliable drop‑in replacement for demanding industrial applications. Constructed from a high‑impact polymer housing, the relay resists corrosion, chemicals, and temperature extremes from –30 °C to +85 °C, ensuring long‑term stability in harsh environments. Inside, a precision‑wound copper coil delivers a stable resistance of 952 Ω ± 5 % at 20 °C, allowing consistent magnetic force and predictable actuation. The device supports a continuous current of 225 A and can tolerate surge currents up to 600 A without degradation, making it suitable for power‑intensive loads such as motor starters, battery isolation switches, and heavy‑duty lighting circuits. Four terminal connections – two 10‑32 mm screws and two 5/16‑24 mm screws – are provided with matching nuts and spacers, simplifying wiring and guaranteeing a secure mechanical bond. The flat‑mount F180 design fits standard panel cutouts, and the single‑pole single‑throw (SPST) configuration offers straightforward on/off control with a low pick‑up voltage threshold of 16.8 V and a quick release voltage of 4.8 V.

Performance testing at the factory confirms that the coil voltage remains within the 24 V ± 10 % range, while the magnetic pull force exceeds the OEM rating, delivering reliable operation even when the supply voltage dips during start‑up transients. The relay’s internal contacts are silver‑plated to reduce resistance and heat buildup, extending service life under repetitive cycling. Each unit undergoes a full functional check, including insulation resistance, coil resistance, and contact resistance measurements, before packaging, guaranteeing that every relay ships ready for immediate installation. The compact 3 × 2 × 4 inch footprint and 1.6 lb weight make the component easy to handle during assembly, and the included mounting hardware eliminates the need for additional accessories. Compatibility listings confirm that the part also substitutes for Johnson Electric 5122240, Prestolite 15‑551, White Rodgers 586‑114111 series, and other common equivalents, providing flexibility for inventory management.
Designed for both OEM and aftermarket use, this solenoid relay integrates seamlessly into existing control panels, PLC‑driven systems, and custom automation rigs. The robust construction tolerates up to 90 % relative humidity, ensuring dependable operation in damp or coastal installations. With a best‑seller rank of #77 in the Solenoids category on major e‑commerce platforms, the product has earned a reputation for durability and value among technicians and engineers. Customer feedback highlights the precise actuation timing, low voltage drop across contacts, and the ease of mounting as key advantages. Whether deployed in construction machinery, forklift power distribution, solar inverter battery banks, or industrial motor control centers, the Fancat solenoid relay delivers the performance and reliability required for mission‑critical applications.
Compatibility extends beyond the original Trombetta part number, covering equivalents such as Johnson Electric 5122240, Prestolite 15‑551, White Rodgers 586‑114111 series, and other cross‑referenced models. This broad compatibility simplifies inventory management for distributors and service technicians, allowing a single stock item to satisfy multiple OEM specifications. The relay’s pinout matches the standard 4‑terminal layout, ensuring that wiring diagrams from various manufacturers can be followed without modification. Detailed datasheets provide the exact terminal assignments, coil voltage, and contact ratings, enabling engineers to integrate the component into custom control panels with confidence.

Usage

In mobile equipment such as excavators, backhoes, and other construction machinery, the relay serves as a primary power control element for hydraulic pump motors, auxiliary lighting, and electronic control units. The 24 V supply matches the standard vehicle battery voltage, while the high current rating accommodates the substantial inrush currents typical of motor start‑up. The rugged housing protects the device from vibration, dust, and oil exposure common on job sites, reducing maintenance intervals and downtime.
Solar energy installations benefit from the relay’s ability to isolate battery banks during fault conditions or when the inverter is offline. The 600 A surge capability ensures safe interruption of short‑circuit events, while the low pick‑up voltage allows the relay to engage quickly even when the solar array output is low during early morning or cloudy periods. The plastic enclosure prevents corrosion from moisture, making the component suitable for rooftop or ground‑mounted arrays.
Industrial automation environments, including conveyor systems, packaging lines, and motor control centers, rely on precise timing and repeatable switching. The SPST configuration simplifies wiring diagrams, and the clear terminal markings reduce installation errors. The relay’s quick release characteristic minimizes coil heating, extending the lifespan of both the coil and the contacts during high‑frequency cycling. Technicians can integrate the unit into PLC‑controlled sequences, using the low pick‑up voltage as a diagnostic indicator for coil health.
In forklift and warehouse truck applications, the relay controls auxiliary power circuits such as lift‑gate motors, lighting, and battery management systems. The 24 V supply aligns with the vehicle’s electrical architecture, while the high current rating accommodates the substantial loads drawn by hydraulic lifts and high‑intensity LED arrays. The compact size permits installation in confined engine compartments, and the rugged housing protects against oil splatter and mechanical shock common in material‑handling environments.
