The Airpax™ SNAPAK® Series combines the functions of three separate components: power switch, fuse, and fuse holder. To the OEM, this means that only one item has to be mounted instead of three. Less assembly is required, inventory is cut by two-thirds and greater panel density is obtainable with less clutter.
Since the SNAPAK® is snap-acting, it assures the immediate opening and closing of the contacts. Its design also prevents operator “teasing” of the contacts and minimizes arcing. SNAPAK® circuit protectors are UL Recognized as supplementary protectors per UL STD. 1077, CSA Certified as supplementary protectors per CSA STD. C22.2 No. 235, TUV Approved as circuit breakers for equipment per STD. EN 60934, CCC Approved (customer must request the product be manufactured in China) and CE Compliant.
Features
- Combines functions of power switch, fuse, and fuse holder
- Can be operated at either DC or 50/60Hz
- Variety of handles and actuators
- Quick-connect terminals available
Applications
- Office appliances
- Electronic data processing
- Medical equipment
- Business machines
- Vending and amusement machines

The 209, E-Frame circuit breaker combines power switching with accurate, reliable circuit protection in a compact single- or multi-pole unit. It is a family of circuit breakers available in one through six pole assemblies with a variety of configurations and terminal styles to meet your application needs. Utilizing the hydraulic-magnetic principle, the 209 Series products adapt to local applications and environments.
Temperature conditions, which affect fuses and other thermal devices, are not a concern. The magnetic/ampere turn principle minimizes nuisance tripping due to temperature variations. Inrush currents, due to ferro resonant transformers, lamps, and capacitive filters, are now becoming more significant. Recognizing the need for this type of protection, Airpax offers the unique inertial delay which is standard for all 50/60Hz time delay units, but may be deleted where inrush is not a problem. The 209 family of circuit breakers withstand high pulses without tripping or affecting normal delay curves. This performance, however, does not derate or sacrifice protection.
Features
- “Trip-free” action — the circuit will not remain closed in the presence of an overload even though the handle is held in the ON position
- Moisture and fungus resistance is provided by the use of moisture-resistant finishes
- 209/219/229 may be supplied with these ratings: DC, 50/60Hz, 400Hz, 0.1 to 100 amperes. 279 types may be supplied with DC ratings only, 0.1 to 100 amperes
- On 209/219/229, voltages up to and including 240Vac, 50/60Hz or 400Hz, or 125Vdc are available. Multi-pole units can be supplied for 277Vac/480Vac, 50/60Hz. 279 types are available with a voltage of 160Vdc
Applications
- EDP
- HVAC/R
- Panel Boards
- Lighting Controls
