FAQ's of CUTLER HAMMER ND 50K 1200A 3 POLE CIRCUIT BREAKER:


Q: How does the CUTLER HAMMER ND31200 circuit breaker provide protection?

A: The ND31200 uses a thermal-magnetic trip unit to detect and respond to overcurrent and short circuit conditions. The thermal component reacts to overloads, while the magnetic mechanism quickly interrupts high fault currents, ensuring reliable protection for connected electrical systems.

Q: What applications is the ND31200 circuit breaker suitable for?

A: This circuit breaker is ideal for industrial and commercial electrical distribution, particularly in three-phase systems where high interrupting capacity and robust protection are critical to facility uptime and safety.

Q: When should the auxiliary contact option be used?

A: Auxiliary contacts are useful when you need remote indication or additional control functions, such as interlocks or alarm notifications. They are typically installed when integration with other monitoring or automation equipment is required.

Q: Where can the ND31200 be installed, considering its temperature range and mounting?

A: With an operating temperature range from -20C to +40C and fixed bolt-on mounting, this breaker can be installed in a wide variety of environments, including industrial switchboards, commercial electrical panels, and power distribution centers.

Q: What is the process for installing this circuit breaker?

A: Installation involves securing the breaker into a compatible panel using bolt-on terminals, ensuring all electrical connections meet manufacturer guidelines and applicable safety standards. A qualified electrician should perform the installation to ensure safety and compliance.

Q: What benefits does the ND31200 offer for users?

A: Users benefit from its high short-circuit breaking capacity (50 kA at 480V AC), extended mechanical life, wide operating temperature range, and compliance with major certifications. This ensures reliable and safe power distribution with minimal maintenance.
