Trane CTR02599 Contactor

The Trane CTR02599 is a 40 A, 2-pole definite‑purpose contactor designed to switch line voltage to compressors, condenser fan motors, electric heaters, and other high‑current HVAC loads in commercial systems. It features a 277 VAC control coil (240 VAC at 50 Hz) and supports 50/60 Hz operation, with a maximum system voltage rating of up to 600 VAC and Class B coil insulation. This OEM replacement contactor is typically panel‑mounted and is commonly used in Trane rooftop units, packaged air conditioners, and other commercial HVAC equipment where reliable electrical switching is essential. It provides electromagnetic control of line voltage while energizing the equipment via low‑voltage or line‑voltage control circuits, making it suitable for applications in commercial office buildings, retail facilities, schools, warehouses, industrial buildings, and other HVAC controls. For compatibility, it aligns with related parts such as Trane CTR01826 (40 Amp 2‑Pole Contactor) and CTR02574 (40 Amp definite‑purpose contactor), as well as Eaton C25 Series 40 Amp 2‑Pole Contactor in matching electrical ratings.
