HVAC Control Breaker 30A 2-Pole

The Federal Pacific UBIF230NB is a bolt-on circuit breaker rated at 30 amps with two poles for 120/240V AC systems. It is designed for use with Federal Pacific NBLP commercial panels. The transparent housing allows visual inspection of the internal mechanism. This new component suits electricians and facility managers maintaining compatible panelboards.

Sustained Load Performance

The breaker carries a maximum AIR rating of 10 kA, indicating its ability to interrupt fault current under demanding conditions. As a standard-type breaker, it provides reliable overcurrent protection for continuous HVAC equipment operation. The ETL listing confirms compliance with applicable safety standards for sustained service. It is not rated for DC voltage applications.

120/240V AC Interface Limits

This device operates solely on 120/240V AC supply and has no DC voltage rating. Physical dimensions measure 3.36 in length, 2.0 in width, and 2.55 in depth for panel fitment. California Proposition 65 warnings apply regarding chemicals known to cause cancer and reproductive harm. Buyers needing DC-rated protection or different pole configurations must select alternative devices.

Questions about this item

Does the 30 A Federal Pacific UBIF230NB run hot or make noise when it carries full load all day?

It is a bolt-on thermal-magnetic breaker with no moving fan, so it operates silently and its temperature rise stays within the ETL-listed limits for continuous 30 A duty in a 120/240 V panel.

What panel hardware must already be in place for this UBIF-series breaker to install and function?

It requires a Federal Pacific NBLP commercial load centre with the correct UBIF bus stab spacing and a free two-pole slot; the breaker bolts directly onto that bus.

Will this 10 kA-rated breaker coordinate with the older 5 kA breakers already in my NBLP panel?

The UBIF230NB carries a 10 kA AIR rating, which is higher than legacy 5 kA units, so it will not trip prematurely and maintains selective coordination when installed in the same panel.
