## W33 series 

## **One- and Two-Pole, Switchable Thermal Circuit Breaker / Power Switch With Optional Indicator Lamp** 

## **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. 

## **Agency Approvals** 

**W33 series is UL 1077 Recognized as Supplementary Protectors, File E69543, and CSA Accepted as Supplementary Protectors (Appliance Component Protectors), File LR15734.** 

Users should thoroughly review the technical data before selecting a product part number. It is recommended that users also seek out the pertinent approvals files of the agencies/laboratories and review them to ensure the product meets the requirements for a given application. 

## **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 **.**

**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.
