3-pole circuit breaker 63A BG1 NZMN1-A63 259083

Power switch – reliable protection of electrical installations

This three-pole power switch with a rated current of 63A is a key element of every safe and efficient electrical installation. Designed by the renowned company Eaton, model NZMN1-A63 provides effective protection against overloads and short circuits, guaranteeing uninterrupted power supply and safety of use. The rated short-circuit breaking capacity of 50kA at 400V, 50Hz demonstrates its high reliability in emergency situations.

Functionality and application

This switch, characterized by a fixed-mounting device construction, finds wide application in both building and industrial installations. The optional possibility of mounting on a DIN TH rail increases installation flexibility, and the setting range of the overload release (50-63A) and short-circuit release (380-630A) allows for precise adaptation to the specific needs of the circuit. The frame terminal facilitates the connection of main conductors, and the front-mounted connections provide convenient access during installation and maintenance.

Key features and benefits

• High short-circuit breaking capacity: 50kA at 400V, 50Hz – ensures a quick and effective response in the event of a short circuit, minimizing the risk of damage.
• Wide adjustment range: Adjustment of the overload release (50-63A) and short-circuit release (380-630A) allows for optimal adaptation to the load characteristics.
• Installation flexibility: Possibility of mounting both directly and on a DIN TH rail – facilitates integration with various types of installations.
• Durable construction: The device made of high-quality materials guarantees long life and reliable operation even in difficult conditions.
• Safety of use: Protection class IP20 protects against accidental contact and the influence of solid objects larger than 12mm.
• Compatibility: NZM..-A series circuit breakers are compatible with LZM/LN series accessories, allowing for flexible expansion of the protection system.
• Simple lever mechanism: Enables intuitive operation and quick disconnection of the circuit if necessary.
• Power loss at 14.2W: Means efficient use of electrical energy during device operation.

Thanks to these features, the Eaton NZMN1-A63 switch is a solid and reliable solution for anyone who values the safety and efficiency of their electrical installation.
