Refurbish 150VCP-W50C Breaker - Photos.pdf

This file contains product images and technical specifications for a Cutler-Hammer electrical switchgear unit, specifically a medium-voltage vacuum circuit breaker system designated SJO1 (model 150VCP-W50 C).

The primary equipment shown is an Eaton Cutler-Hammer vacuum interrupter-based circuit breaker assembly rated at 17.5 kV maximum voltage, 1200 A continuous current, with a 60 Hz power frequency rating and 50 ms interrupting time. Key technical parameters include a short-circuit current rating of 50 kA rms with 139 kA peak close and latch current, 630 A rms capacitance current switching capability for both single bank and back-to-back configurations, and 15 kA peak inrush current at 3500 Hz frequency. The unit features three vacuum interrupter elements with red operating mechanisms, a control voltage range of 70-140 Vdc (Trip #1) with 6.6 A trip current, and close control voltage range of 100-140 Vdc with 5.5 A close current. Additional components include WL35123C type vacuum interrupters mounted within cylindrical porcelain housings, stacked conductor terminals with pin connectors, and associated control wiring. The unit is manufactured in the USA, weighs 460 lbs, and includes instruction book number 32-255-1G with multiple serial numbers visible on component labels (03084859, 0306N58112, 0306N58126, and others). The equipment is mounted on a wooden pallet with red structural framing, indicating it is industrial electrical apparatus suitable for medium-voltage power distribution systems.
