I chose a Siemens panel and this breaker to do so. Power is provided to this panel via a 3 phase rotary converter. So, for been working great. I can run any 3 phase machine now up to 7.5hp. Though I currently only have the Jointer. ## Features - Made in Mexico ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00A2V16C8 | | Batteries Included? | No | | Batteries Required? | No | | Best Sellers Rank | #136,097 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #87 in Miniature Circuit Breakers | | Brand | SIEMENS | | Circuit Breaker Type | Standard | | Color | Black | | Current Rating | 30 Amps | | Customer Reviews | 4.6 4.6 out of 5 stars (139) | | Date First Available | November 6, 2012 | | Item Package Quantity | 1 | | Item Weight | 1 pounds | | Item model number | Q330 | | Manufacturer | Siemens | | Material | Copper | | Mounting Type | Plug-In Mount | | Number Of Poles | 3 | | Part Number | Q330 | | Product Dimensions | 30"D x 8"W x 6"H | | Voltage | 240 Volts | ## Product Details - **Brand:** SIEMENS - **Circuit Breaker Type:** Standard - **Current Rating:** 30 Amps - **Mounting Type:** Plug-In Mount - **Product Dimensions:** 30"D x 8"W x 6"H ## Images ![Q330 Circuit Breaker 30a 3p 240v 10k Qp - Image 1](https://m.media-amazon.com/images/I/61D9mQjWEYL.jpg) ## Questions & Answers **Q: will this work on a Gould ITE breaker box?** A: Yes.
