RDQ3NMA 3 Pole Automatic Transfer Switches for Generator Transfer Switch Kit
RDQ3NMA 3 pole automatic transfer switches series has 5 sizes, which are 125A, 250A, 400A, 630A, 800A. It is with A type controller and LED indicator. We design and developed the ATS by our own R&D team. Radin's ATS is featured with elegant outlook and distinguished design.
Overview: This controller is a type economic controller developed as per to market demand. It has the features of simple operation, and is suitable functions and display intuitive etc.. This controller has advantages of stable quality, reliable performance, high anti electromagnetic interference ability, etc. It is widely used in various kind of severe environment with strong electromagnetic radiation and interference. AC-32B utilization category per IEC/EN 60947-6-1 standard.
Structure Introduction
RDQ3NMA 3 pole automatic transfer switches use category of AC-32B, and electrical appliance grade is CB class.
RDQ3NMA ATS consists of two 3P or 4P MCCB and its accessories (auxiliary contact, alarm contact), mechanical interlocking transmission mechanism, intelligent controller, etc. The overall structure in which the controller and the execution unit are installed on the same base;
Feature
● There is a reliable mechanical interlocking device and electrical interlocking protection between the two molded case circuit breakers, which completely avoids the possibility of the two molded case circuit breakers being powered on at the same time;
● It has short circuit and overload protection functions;
OEM/ODM Service
Support using customer brand MCCB as main switch.
