Description
Designed for heavy-duty power distribution, this 60A single-pole breaker offers reliable thermal-magnetic trip functions for commercial facilities. The unit installs into Siemens P1, P2, and P3 panelboards using a secure bolt-on mounting configuration. With a 100kAIC interrupting capacity at 120VAC, it easily manages demanding electrical faults. This model does not include load lugs and is superseded by the 3VA5160-4ED14-0AA0, which requires an additional strap kit for legacy P1 enclosures.Specifications

Product FAQs
7 answersWhich panelboards are compatible with the NGB1B060 circuit breaker?
This bolt-on breaker is designed for use in Siemens P1, P2, and P3 commercial panelboards. It is not compatible with standard residential load centers.
What wire sizes are accepted by the lugs on the NGB1B060?
The standard TC1Q1 lugs on this 60A breaker accept #8 to 1/0 AWG copper wire, or #8 to 2/0 AWG aluminum wire.
How does the NGB1B060 connect to the panelboard bus?
It features a bolt-on connection type, meaning the line side of the breaker physically bolts to the panelboard bus for a secure, vibration-resistant installation.
Can the NGB1B060 be used in DC voltage applications?
Yes, this breaker is rated for DC applications up to 125VDC with an interrupting capacity of 14kAIC.
What is the difference between Siemens NGB, HGB, and LGB breakers?
These breakers share the same GG frame size and panelboard compatibility but have different short-circuit interrupting ratings. The NGB is the standard tier, while the HGB and LGB offer higher interrupting capacities.
What does the LI trip function code mean on this breaker?
The LI designation indicates that the thermal magnetic trip unit includes both Long-Time overload protection and Instantaneous short-circuit protection. Both settings are fixed on this model.
Is the NGB1B060 designed with a trip-free mechanism?
Yes, it features an over-center toggle mechanism that is trip-free. If a short circuit or overload occurs, the contacts will force apart and trip the breaker even if the handle is physically held in the ON position.
