FAQs
Installation requires coordinating the three‑pole, top‑feed configuration with your existing feeder layout. Verify system voltage is 208 V and control voltage is 120 V. Ensure mounting clearance for the 180 lb unit, connect phase wires to the three poles, and integrate auxiliary/provisions as needed. Follow manufacturer torque specs and verify UL listings after assembly.
The capacitor trip device (SPVR) provides a rapid, controlled trip sequence to interrupt faults with minimal arcing and coordinated timing. This reduces thermal and mechanical stress on motors and switchgear, improves fault discrimination, and helps prevent nuisance trips during inrush, thereby extending equipment life and stabilizing production uptime.
Yes. The unit is rated for 208 V system voltage and uses a 120 V control circuit, aligning with many low‑voltage motor control configurations. It supports three‑pole, three‑wire operation and is designed to integrate with typical MCC and panel layouts in industrial facilities while maintaining full UL Listed compliance.
The CB2033T120208RARCT carries UL Listed certification, with NEMA ratings including 1, 3R, 4, and 12, indicating suitability for both indoor and outdoor/industrial environments. It is fusible protected and designed for single‑phase protection with optional ground fault and auxiliary provisions, ensuring regulatory alignment and enhanced safety performance.
Eaton provides a standard warranty per policy 25‑000, covering one year from installation or eighteen months from shipment, whichever occurs first. Regular maintenance should include inspection of contacts, trip mechanism, and auxiliary circuits; verify BFD indicators and protections are functional, and replace fusible elements or components as recommended by Eaton’s service guidelines.
