Product Specifications

Multi 9 - GFP - RCCB - 4P - 63A - class A SI - 480Y / 277V - 86mA instantaneous

This product description appears to be a list of technical specifications. Here's a possible breakdown: * **Multi 9:** This could be the brand or model name. * **GFP:** Likely an abbreviation for a specific feature or technology. * **RCCB:** Stands for Residual Current Circuit Breaker, a safety device that protects against electrical shock. * **4P:** Indicates a four-pole breaker, meaning it protects all live and neutral conductors. * **63A:** The maximum current rating of the breaker (amperes). * **Class A SI:** Refers to the sensitivity class of the RCCB. "SI" likely stands for "Selective Instantaneous." * **480Y / 277V:** The voltage range the breaker is designed for. "Y" usually indicates a wye connection. * **86mA instantaneous:** The maximum residual current that will trip the breaker instantaneously (milliamperes).
