Description
Built for reliable performance in demanding environments, the Siemens NGG3B060L is a 60A, 3-pole molded case circuit breaker from the SENTRON family. It utilizes proven thermal-magnetic trip technology to deliver long-time and instantaneous (LI) protection. Designed for unit mounting, it fits perfectly into Siemens P1 panelboards, control panels, and DIN rail setups. With a 25kAIC interrupt rating at 480VAC and reverse feed capabilities, it is replaced by the 3VA5160-4EC31-0AA0.Specifications

Product FAQs
8 answersDoes the Siemens NGG3B060L require a separate adapter for DIN rail mounting?
No. The GG frame design allows this breaker to be mounted directly onto a standard DIN rail or base-mounted without the need for additional mounting plates or adapters.
What is the difference between Siemens NGG, HGG, and LGG circuit breakers?
These prefixes represent different interrupting capacity levels within the same physical G-frame size. NGG provides standard interrupting ratings, such as 25kAIC at 480VAC. HGG provides high interrupting ratings, and LGG offers extra-high interrupting ratings for systems with higher available fault current.
What wire sizes and materials are compatible with the standard lugs on the NGG3B060L?
The included standard lugs accept 8 to 1/0 AWG copper wire or 8 to 2/0 AWG aluminum wire. Always ensure the conductor ampacity is properly rated for the 60A continuous load requirement.
Can the Siemens NGG3B060L be used in direct current (DC) applications?
Yes. In addition to alternating current applications up to 600Y/347VAC, this thermal-magnetic circuit breaker is rated for 14kAIC at 125/250VDC.
What are the primary applications for the NGG3B060L feed-thru circuit breaker?
It is frequently used as an incoming main or branch breaker in Siemens P1 panelboards, standard DIN rail enclosures, and industrial OEM control panels.
Are the trip functions on the NGG3B060L field-adjustable?
No, the long-time and instantaneous (LI) thermal-magnetic trip functions are fixed. If your application requires precise coordination adjustments, an electronic trip breaker may be required instead.
Does the NGG3B060L feature a trip-free mechanism?
Yes, the GG frame uses an overcenter toggle mechanism that is trip-free. During a short circuit or overload condition, the contacts will force apart and the breaker cannot be physically held closed by the handle.
Can I install this Siemens circuit breaker in GE or Eaton panelboards?
No. Siemens circuit breakers are engineered and tested strictly for compatible Siemens distribution equipment. Cross-brand installation violates UL listings and poses a severe fire hazard due to high-resistance connections on the bus bar.
