Frequently Asked Questions
What are the maximum operating voltages for this circuit breaker?
The maximum operating voltages are 50VDC and 250VAC to 400 Hz.
What is the interrupt capacity of the W33 series breaker?
It has an interrupt capacity of 1,000 amps at 50VDC and 250VAC, 60 Hz. and 125/250VAC, 400 Hz.
What is the resettable overload capacity of the breaker?
The resettable overload capacity is ten times the rated current.
What are the available amp ratings for this circuit breaker?
Available amp ratings are from 2 to 20 amps. Ratings below 2A are available as special order.
How does the breaker perform at 135% of its rated load?
The breaker may trip between 101% and 135% of rated load, but must trip at 135% within one hour at +25°C.
What is the dielectric strength of the W33 series breaker?
The dielectric strength is over 2,000 volts RMS.
What agency approvals does the W33 series have?
The W33 series is UL 1077 Recognized and CSA Accepted as Supplementary Protectors.
How does ambient temperature affect the breaker's trip curve?
Ambient temperature affects the breaker's rating via a correction factor. Multiply the breaker rating by this factor to get a compensated rating.
What is the switch endurance cycling rating for this product?
The switch has an endurance of 50,000 operations at rated load and 1,000 operations at 200% rated load.
What types of terminals are used for this circuit breaker?
Poles 1&2 use .250” (6.35mm) quick connect/solder terminals. Optional auxiliary switches use .110” (2.79mm) quick connect terminals.
