NZMB2-M200 Power switch 3-pole 200A motor protection 265717

Three-pole circuit breaker 200A – reliable installation protection

This three-pole circuit breaker from Eaton, with a rated current of 200A, is a key element in protecting the electrical installation. It provides effective protection against overloads and short circuits in three-phase circuits, guaranteeing safety and longer life of connected devices. It is a solid solution for both professional installers and end-users who value reliability and peace of mind.

Functionality and application

The NZMB2-M200 circuit breaker with a thermal-magnetic characteristic is designed to operate in installations with a rated voltage of 440V. Its construction allows mounting on a DIN rail in a vertical position, with the possibility of rotation by 90 degrees in any direction – which facilitates installation even in tight spaces. The rated operating power for AC-3 is 110 kW at 400V and 55 kW at 230V, making it suitable for protecting various receivers, including electric motors. The built-in thermal protection additionally protects against the effects of prolonged overload.

Key features and benefits

• High short-circuit breaking capacity: Rated short-circuit breaking capacity Icu at 18.5 kA at 400V AC guarantees quick and safe disconnection of the circuit in the event of a short circuit.
• Precise adjustment: The adjustment range of the overload release (160-200A) and the short-circuit release (1600-2800A) allows you to adapt the circuit breaker characteristics to the specifics of the protected installation.
• Solid construction: The device made of high-quality materials ensures durability and reliable operation for a long time. The fixed construction of the device ensures stability and safety of use.
• Easy installation: Screw connection of the main contacts facilitates the connection of wires, and compact dimensions (149 mm depth x 105 mm width x 184 mm height) allow you to save space in the switchgear cabinet.
• Safety: Protection class IP20 provides protection against accidental contact and against the ingress of solid objects larger than 12.5 mm.
• Phase failure protection: Insensitivity to phase failure avoids unnecessary tripping of the circuit breaker in the event of temporary power disturbances.

This circuit breaker is not only a protective element, but also an investment in the safety and trouble-free operation of the entire electrical installation.
