Its design also prevents accurate, reliable circuit protection in one aesthetically pleasing operator teasing of the contacts and minimizes arcing. package. The SNAPAK combines the functions of three SNAPAK circuit protectors are UL Recognized as separate components: power switch, fuse and fuse holder. To the supplementary protectors per UL STD. 1077, CSA Certified as OEM, this means that only one item has to be mounted instead supplementary protectors per CSA STD. C22.2 No. 235, TUV of three. Less assembly is required, inventory is cut by two- Approved as circuit breakers for equipment per STD. EN 60934, thirds and greater panel density is obtainable with less clutter. In CCC Approved (customer must request product be manufactured addition, the SNAPAK can be operated at either DC or 50/60Hz, in China) and CE Compliant. In addition, most versions are eliminating the need to specify, order and stock separate units. certified by UL to meet spacing requirements of IEC 950 for basic 400Hz units are also available. and functional insulation for front panel mounting. To enhance front-panel aesthetics, SNAPAK is offered with Consult factory for details and exceptions. Typical applications paddle and rocker handles in six attractive colors and push-pull include office appliances, electronic data processing, medical and push-to-reset actuators. Also offered is a variety of optional equipment, business machines, vending and amusement mounting hardware. The push-pull version is supplied with a machines. Push-pull versions are particularly well suited for black button with a white indicating band. medical instrumentation, automotive production transfer lines and other applications where accidental turn off is unacceptable. Orientation of the button when marked with an amperage For those applications which do not require circuit protection, notation must be specified when using the fourth decision table. SNAPAK is offered in a power-switch-only configuration. Push-to-reset is supplied with a contrasting color indicating shaft. In addition, SNAPAK is offered in SPST and DPST configurations. The single pole satisfies most applications. The two-pole version is often used for extra safety in products that utilize high voltage or where current sensing and breaking of both sides of the line is required. Quick connect terminals are standard, UNC 8-32 or M4 screw terminals are available as additional termination options. 55 SNAPAK Series - Introduction
