Product Description
Delta CA302R
3‑Wire • Single Phase • 250VAC Surge Capacitor
Delta Surge Capacitors are designed to protect electrical and electronic equipment from fast, low‑energy voltage spikes that traditional surge arrestors cannot react to. The Delta CA Series absorbs and controls small, harmful surges—up to 6,000 volts—helping safeguard sensitive devices and extend system life.
The CA302R is built for 250V single‑phase, 3‑wire service and is ideal for residential and light commercial service entrance panels. Each unit includes an internal automatic discharge circuit for added safety and reliability.
