 GFCI Circuit Breaker Boots  ::  Rocker Style
GFCI Circuit Breaker Boots     
Availability:  In-Stock: Inch & Metric

Ground Fault Circuit Breaker Environmental Sealing Boot
To achieve a higher level of environmental sealing performance and reliability, we recommend attaching the APM HEXSEAL® 1113/25 harsh elements sealing boot (cover) to the Carling Technologies PB-Series Ground Fault Circuit Breaker (rocker style) it was specifically designed to mate with. The 1113/25 breaker boot is IP66/68 ingress rated, ROHS certified, manufactured to the most demanding military specification MIL-DTL-5423. The 1113/25 will protect against penetration from water, moisture, dust, dirt, ozone, UV, fungus, lubricants, cleaning chemicals and most acids — some of the invasive, corrosive contaminants these circuit breaker GFCI devices are subject to on boats, in marinas and large back up generators.

Status visibility and tactile feel during the life of the sealing boot is critical.
To maintain absolute visibility throughout the full life of circuit breakers, APM molds the boot with its proprietary RUBRGLAS® silicone rubber, distinguished by its clear-blue tint. To prevent "yellowing" a special chemical formulation is used to maintain its integrity and resist ozone and UV degradation. The pure silicone rubber used by APM promotes smooth positive interaction between the finger and the actuators.

Even the mounting screws represent an important sealing system enhancement.
Four stainless steel special (APM SEELSKREW® mounting screws secure the zinc chromate plated mounting frame which mounts on the front of the panel. (Aluminum and stainless steel mounting frames are available upon request.) The sealing screws incorporate an internal sealing system consisting of an embedded silicone O-Ring in an asymmetrical groove that seals to 20,000psi internal/external, a function too important to be handled by common screws.

Agency Regulations: All Circuit Breaker Boots are UL-Recognized Components to UL Std. 50, Types 1, 2, 3R, 3S, 4(X), 6P, 12, 12k & 13. UL Recognition also includes compliance with Canadian National Standards.

About APM's Sealing Boots Division:
The Electronics Division of APM HEXSEAL develops and manufactures environmental protection sealing components for controls that are mounted on switches, potentiometers, encoders, and circuit breakers. Using advanced elastomer molding technology, a broad range of sealing boots are produced to match most controls manufactures’ standard part numbers. Most are IP66/68 ingress protection rated and UL Recognized as meeting applicable Canadian and USA enclosure protection standards.

About APM's Self-Sealing Fastener Division:
The APM line of high-pressure, reusable, self-sealing fasteners includes self-sealing screws, self-sealing nuts, self-sealing bolts, self-sealing rivets, and self-sealing washers, all designed to seal in/out air, water, lubricants and other liquid or gaseous contaminants. This sealing hardware is available in Imperial (inch) and metric sizes with various sealing material and thread-locking options, most of which are UL Recognized Components for Canada and the USA.
