- UL 489 listed and CE marked for US, Canadian and European compliance
IEC Miniature Circuit Breaker
The Dayton 33V907 is a three-pole thermal magnetic circuit breaker rated at 6 A for 480 V AC circuits. It carries a 10 kA interrupting rating and mounts on a standard DIN rail for panel installation.
Compatibility Check
Verify that the panel uses DIN rail mounting and that the supply voltage does not exceed 480 V AC. The lug terminals accept wire sizes from 53 AWG to 69 AWG, so confirm your conductors fall within that range. The breaker is not rated for DC applications, so it must not be used on DC circuits.
Build Integration
This 3-pole unit occupies a 4.6 in by 2.13 in footprint with a 3 in depth inside the enclosure. It provides overcurrent protection for three-phase loads up to 6 A while meeting UL 489 and CE standards. The toggle actuator allows manual reset after a trip event.

Questions about this item
What comes in the box and what else must be purchased to install the 33V907 breaker?
The breaker itself is supplied. You will need to buy DIN rail, mounting hardware and suitably rated wire separately.
How do I choose between the available versions of the NDB2T-63 series for my application?
Select the 6 A, 3-pole, B-curve version when your load requires 6 A protection on three phases with a B-type trip characteristic.
What does the 10 kA AIR rating mean when the breaker is fitted in a 480 V AC panel?
It means the breaker can safely interrupt fault currents up to 10 kA at 480 V AC without damage.
