Product FAQs
7 answersWhat is the difference between Siemens NGG and NGB circuit breakers?
The NGG frame is designed for global applications and can be independently mounted on a 35mm DIN rail or secured with mounting screws. The NGB frame shares the same internal design but is specifically configured for panelboard mounting and lacks some of the global markings found on the NGG.
Does the NGG2B080L require an adapter for DIN rail installation?
No, this breaker features an integral design that allows it to be mounted directly onto a standard 35mm DIN rail without the need for additional mounting plates or adapters. It can also be secured to a backpan using standard mounting screws.
Are the line and load lugs included with this breaker?
Yes, the breaker comes standard with factory-installed line and load side lugs. These feed-thru terminals accept 8 AWG to 1/0 AWG copper or 8 AWG to 2/0 AWG aluminum conductors.
Can the NGG2B080L be used in DC power applications?
Yes, this breaker is rated for direct current applications up to 125/250VDC with an interrupting capacity of 14kAIC.
Are the trip settings on the NGG2B080L adjustable?
No, this breaker features a fixed thermal-magnetic trip unit. The long-time and instantaneous trip functions are factory preset and cannot be adjusted in the field.
Is this breaker suitable for use in HVAC equipment?
Yes, the NGG2B080L is HACR rated, meaning it is approved for use with heating, air conditioning, and refrigeration equipment.
Can the Siemens NGG2B080L be reverse fed?
Yes, this breaker is suitable for reverse feed applications according to UL 489 standards because the thermal-magnetic trip unit is fixed and not removable.
