Ambient Temperature In Degrees Centigrade (°C)

To use this chart: Read up from the ambient

temperature to the curve, and across to find a

correction factor. Multiply the breaker rating by the

correction factor to determine the compensated

rating. Calculate the overloads in terms of the

compensated rating to use the published trip curve.

Features

• Combines on/off switch and circuit protection in a single unit.

• 2 to 20 amp ratings (<2A types available as special order).

• One or two pole sensing.

• Lighted or non-lighted rocker actuator in various colors.

• Convenient, snap-in mounting.

• Optional auxiliary switch available.

• Trip-free operation.

Electrical Data @ 25°C

Calibration: Breaker will continuously carry 100% of rated load. It may trip

between 101% and 135%, but must trip at 135% within one

hour at +25°C.

Dielectric Strength: Over 2,000 volts RMS.

Maximum Operating Voltages: 50VDC; 250VAC to 400 Hz.

Interrupt Capacity: 1,000 amps at 50VDC; 250VAC, 60 Hz. and

125/250VAC, 400 Hz.

1,500 amps at 125/250VAC, 60 Hz.

Resettable Overload Capacity: Ten times rated current.

Mechanical/Environmental Data

Termination: Poles 1&2: .250” (6.35mm) quick connect/solder terminals.

Opt. Aux. Sw.: .110”(2.79mm) quick connect terminals.

Mounting: Snaps into panel from front.

Actuator: Rocker or lighted rocker.

Shock: 30g tested to IEC 68-2-27, test Ea.

Vibration: 8g tested to IEC 68-2-6, test Fc.

Switch Endurance Cycling:

50,000 operations at rated load.

1,000 operations at 200% rated load.

Agency Approvals

W33 series is UL 1077 Recognized as Supplementary Protectors, File
