Trip Free
AP circuit protectors will trip open on overload, even
when forcibly held ON. This prevents the operator from
damaging the circuit by holding the handle in the ON
position.
Trip Indication
The operating handle of the breaker moves forcibly and
positively to the OFF position on overload. It is not
necessary to manually “reset” to full “OFF” in order to turn
it on again.
Ambient Operation
The protector will operate at any ambient between –40°
C and +100° C, when tested in accordance with the
requirements
of MIL-PRF-39019.
Insulation Resistance
Exceeds 100 megohms at a potential of 100Vdc.
Dielectric Strength
The protector will withstand 1250 volts RMS, 60Hz from
terminals to case and between the terminals when open.
Endurance
With the circuit protector operated as an ON-OFF switch,
operating life exceeds 10,000 operations at a rate of 6 per
minute when tested as follows: 6000 OPS @ rated current
plus 4000 OPS @ no load.
Ratings
AP protectors are available in current ratings from 50
milliamperes to 20 amperes, 50 volts DC or 240 volts AC,
maximum, 60 Hz or 400 Hz. UP protectors are UL 1077
and CSA approved as per the following table. Please
consult factory for ratings other than those noted.
RATINGS
Lever Strength
The operating lever or its seal will not be damaged by a 10 lb.
force applied in any direction.
Shock
All protectors withstand 100G without tripping, even while
carrying full rated current with shock applied in any plane
of 6 ms duration. Test is made according to Method 213, Test
Condition I or MIL-Std-202 as outlined in Paragraph 4.6.14 of
MIL-PRF-39019. Delay 40, 50 and 60 breakers are tested at 80%
of rated current.
Vibration
All protectors withstand vibration from 10 to 55 cycles at .06
double amplitude and 55 to 2000 cycles at 10G, applied in
any plane, without damage and without tripping even while
operating at full rated current. Test is made in accordance
with Method 204A, Test Condition C, of MIL-Std-202 as
outlined in Paragraph 4.6.12 of MIL-PRF-39019. Delay 40,
50 and 60 protectors are tested at 80% of rated current.
Short Circuit Capacity
When tested in accordance with the procedures of UL1077,
AP supplementary protectors have a short circuit capacity of
1000 amperes at 32Vdc, 120Vac, 240Vac, 60 or 400Hz. Parts
are recognized to UL1077 for type UP1 only. The rated Rupture
Capacity per MIL-PRF-39019 is 500 amperes, 50 volts DC, 500
amperes, 120 volts AC and 300 amperes, 240 volts AC, 60 or
400Hz.
Case Seal
The breaker is fully sealed and will not show evidence of
leakage under total immersion. Meets requirements of MIL-
PRF-39019.
Panel Seal
The “O” ring provides, with the other illustrated hardware, a
seal against a pressure differential of 15 psi applied for an hour.
