Product FAQs
7 answersWhich panelboards are compatible with the NEB1B020B circuit breaker?
The NEB1B020B is designed for use in Siemens P1, P2, P3, P4, and P5 panelboards. It requires a bolt-on connection and the appropriate NEB or HEB mounting hardware kit for your specific panel type.
Can the Siemens NEB1B020B be used in DC applications?
Yes, this breaker is rated for DC applications. It provides an interrupting capacity of 35kAIC at 125VDC, making it suitable for control circuits and other low-voltage DC systems.
Is the NEB1B020B rated for 347V systems?
Yes, this breaker is rated for 347VAC systems, which are frequently used in Canadian commercial and industrial lighting applications. It has an interrupting rating of 22kAIC at 347VAC.
What wire sizes and materials are accepted by the NEB1B020B lugs?
The factory-installed load lugs on the NEB1B020B accept copper (Cu) or aluminum (Al) wire ranging from 14 AWG to 1/0 AWG. Ensure proper torque specifications are followed during installation.
What is the difference between Siemens NEB and HEB frame breakers?
Both NEB and HEB breakers share the same physical frame size and mount in the same Siemens panelboards. The primary difference is the interrupting capacity. HEB breakers offer a higher kAIC rating than standard NEB breakers like the NEB1B020B.
Does the NEB1B020B require a plug-on or bolt-on connection?
The NEB1B020B is a bolt-on circuit breaker. It physically bolts to the panelboard bus using specific mounting hardware, providing a secure mechanical and electrical connection required in many commercial and industrial environments.
What type of trip functions does the NEB1B020B include?
It features a thermal-magnetic trip unit with fixed long-time and instantaneous (LI) trip functions. This provides standard overload protection (thermal) and short-circuit protection (magnetic).
