The Eaton Industries MCCB motor protection switch is designed for built-in, fixed installation, with dimensions of 105x149x195mm. The nominal continuous current is 18A and the connection method for the main circuit is a screw connection. The switch-off technique is magnetic and it has a protection rating of IP20. The operating voltage is 690V. The NZM..-S..CNA series circuit breakers suit all applications with just four compact sizes. They have a modular function group for flexible installation and a magnetic short-circuit release in combination with an overload relay. They also feature a short-circuit release without overload trip. Compliant with UL/CSA and IEC regulations, the rating plate displays IEC switching performance values.
