The circuit breakers of the NZM..-S..CNA series cover all application cases with just four compact sizes and are suitable for worldwide use. The installation is always flexible due to modular functional units. They feature a magnetic short-circuit release in conjunction with motor protection relays, and a short-circuit release without overload release. Notes: The switches comply with both UL/CSA and IEC regulations. IEC switching capacity values are included on the rating plate.
