Trip Free
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.
Insulation Resistance
Will not be less than 100 megohms at 500 volts D.C.
Endurance
Test to be performed at rated current and rated voltage at
3mSec time constant DC. Rate of operation to be 5
operations per minute for breakers rated at 250 amps and
less and 4 per minute for breakers rated above 250 amps.
Breakers rated above 250 amps but 600 amps or less shall
be rated for 1000 loaded operations and 5000 mechanical
operations.
Auxiliary Switch
When supplied will be S.P.D.T. configuration with a
maximum rating of 10 amperes 250 VAC 1 amp 80 Vdc.
When optional metering shunt or parallel pole configuration
is specified, maximum rating is 1 amp 80 Vdc.
High-Low Temperature
Circuit breakers will operate in the range from -40°C to
+85°C. All agency testing is conducted with wire sized per
75°C chart of the National Electrical Code. In all cases the
breaker connections should be sized to limit the maximum
terminal temperature to 100°C absolute when the breaker is
operating in the maximum ambient temperature at the
maximum load current.
Overload
DC rated circuit breakers will withstand 50 operations at
600% of rated current. The current shall have no less than a
3mSec time constant at rated voltage. Units to be operated
in groups of five at the rate of operations per minute with
fifteen minutes between groups to allow for cool down.
Dielectric Strength
Circuit Breaker will withstand 1000 volts plus twice rated
voltage 60 Hz AC for 60 seconds from terminal to terminal.
Voltage Ratings
On all types, voltages up to and including 160 volts DC.
Multi-pole units can be supplied for 125/250 volts Vdc. All
units will be marked with the standard maximum voltage.
UL listed breakers will be labeled with the UL listed voltage.
DC Applications (typ)
A choice of delays is offered for DC applications. Delay 51
is a short delay for general purpose applications. Delay 52
is long enough to start certain types of motors and most
transformer and capacitor loads. Delay 53 is a long delay
for special motor applications.
All trip curves and trip currents are specified with the
breaker mounted in the normal vertical position at ambient
temperature of +25°C. For test and measurement purposes,
the breakers should not carry current prior to application
of overload for calibration test. For other than vertical
mount position, consult factory.
General notes for Agency Approvals
All supplementary protectors are of the overcurrent (OC) type
The family of protectors has been evaluated for end use application for use group (UG) A
The terminals (FW) – Terminals are coded as follows:
0 – Suitable for factory wiring only
1 – Line terminals evaluated for field wiring
2 – Load terminals evaluated for field wiring
3 – Line and load terminals evaluated for field wiring
The maximum voltage ratings for which the protectors have been tested are shown in the chart
The current is the amperage range that the protectors have been tested
The tripping current (TC) – Tripping current is coded as a percentage of the ampere rating
0 – Tripping current is less than 125% of ampere rating
1 – Tripping current is in the range of 125% to 135% of ampere rating
2 – Tripping current is more than 135% of ampere rating
3 – Tripping current is 135% and meets MCCB trip time requirements
The overload rating (OL) - designates whether the protector has been tested for general use or motor starting applications.
0 – tested at 1.5 times amp rating for general use
1 – tested at 6 times AC rating or 10 times DC rating for motor starting
The short circuit current rating (SC) – The short circuit rating in amperes following a letter and number designating the test conditions and any calibration following the
short circuit test is defined below:
C – Indicates short circuit test was conducted with series overcurrent protection
U – Indicates short circuit test was conducted without series overcurrent protection
1 – Indicates a recalibration was not conducted as part of the short circuit testing
2 – Indicates a recalibration was performed as part of the short circuit testing
3 – Indicates recalibration was performed along with the dielectric and voltage withstand for “Suitable for Further Use” rating
