Distinctive Characteristics

Guide interlocked with actuator block prevents window locking and

maintains correct plunger alignment to assure contact stability.

Employs an over-center actuator mechanism, which diminishes

sparking and increases operating life in AC circuits.

High torque bushing construction prevents rotation

or separation from frame during installation.

Splashproof option (D3 and B3 bushing codes) features

an o-ring within the bushing and one under the face nut

to protect from splashed, sprayed, or spilled liquids.

Splashproof models meet IP67 of IEC 60529 Standards

at front panel (dust tight and water protected from

effects of temporary immersion).

High insulating barriers, formed in the molded

diallyl phthalate case, increase isolation of circuits

in multipole devices.

Prominent external insulating barriers increase

insulation resistance and dielectric strength.

Epoxy sealed terminals prevent entry of solder

flux and other contaminants.

Clinching of the frame to the case well above the base

and terminals provides 1,500V dielectric strength.
