Eaton C25BNB240A (45GG20AF) Contactor

The Eaton C25BNB240A is a commercial-grade 2-pole definite purpose contactor engineered for demanding HVACR and industrial motor control applications. This 40-amp contactor provides a direct replacement for the Siemens 45GG20AF, featuring an inductive full-load rating of 40A and a resistive rating of 50A. Designed with a 110-120Vac 50/60Hz coil, this unit ensures reliable switching for compressors, fans, and resistance heating elements. The compact C25 series frame utilizes an open-type enclosure and a robust metal mounting plate for secure installation in control panels. Each unit incorporates binding head screw terminals and side-by-side quick-connect terminals, facilitating efficient field wiring and reduced labor time. This non-reversing contactor is UL Recognized and CSA Certified, meeting strict industry standards for reliability in high-cycle environments such as food service equipment and data processing cooling systems.

Key Benefits

• Broad Compatibility: Serves as a technical equivalent to the 45GG20AF and various Cutler-Hammer C25 models.
• Enhanced Durability: The open-type enclosure design helps dissipate heat while the metal plate provides superior structural rigidity.
• Flexible Terminals: Dual-purpose binding head screws and quick connects support diverse wiring configurations.
• High Amperage Rating: Optimized for inductive loads up to 40A, making it ideal for large HVAC compressors and motor starters.

Common Questions

• Can this replace a 30-amp contactor? Yes, the 40-amp rating exceeds 30A requirements, providing a more robust overhead for inductive inrush currents.
• Is the mounting plate universal? The Eaton C25 contactor series features standard mounting holes designed to eliminate the need for re-drilling in most service applications.
• What is the coil's power requirement? This model requires a standard 120V control signal (110-120Vac) to energize the magnetic structure.
