Carling: PC-Series Ground Fault Circuit Protection

Monday, July 11th, 2011

Carling Technologies Inc is pleased to announce the addition of the 1-50 Amp PC-Series circuit breaker to its ground fault circuit breaker product portfolio.
The PC-Series is suitable for:

  • AC branch ground fault protection – a single circuit solution
  • AC main ground fault protection for a boat’s entire AC electrical system
  • Portable generator ground fault protection

Key Benefits of the PC-Series:

  • Increases safety around boats and marinas
  • Protects against electrical shock hazards in areas near water
  • Protects against defects in the wires & conductors
  • Reduces fire and shock hazards from defects in permanently installed appliances such as water heaters, battery chargers, lighting fixtures, etc.
  • Detects lower level ground faults which do not trip ordinary circuit breakers, but can lead to fires, and shock hazards for boating occupants

Innovative Features:

These precision mechanisms are temperature stable and are not adversely affected by temperature changes in their operating environment. As such, derating considerations due to temperature variations are not normally required, and heat-induced nuisance tripping is avoided.

  • Overload, short circuit and ground fault protection in a single package
  • Handle style actuators and rocker style “acuguard”
  • Wiping Contacts – Mechanical linkage with two-step actuation – cleans contacts, provides high, positive contact pressure & longer contact life
  • A trip-free mechanism, a safety feature, makes it impossible to manually hold the contacts closed during overload or fault conditions.
  • A common trip linkage between all poles, another safety feature, ensures that an overload in one pole will trip all adjacent poles.
  • Front panel mounting
  • Integral push-to-test button
  • Two integrated LED indicators distinguish if a breaker is closed with Line Voltage present, or has opened due to leakage current, or has opened due to over current, or is closed with no Line Voltage present.

SEELOC® self-sealing washers become popular in alternative energy industry

Tuesday, May 31st, 2011

 

Mounted on a NEMA enclosure, independent of the tower,  or within the turbine nacelle, SEELOC — self-sealing washers are finding new applications  for sealing doors and knockouts. For use wherever environmental internal seepage  is problematic — when a common washer is unable to block contaminants,  such as moisture, dust, sunlight, and ozone.  SEELOC is a natural for green applications.

SEELOC® self-sealing washers are vibration-resistant, each having a silicone rubber section, molded and bonded to a stainless steel formed washer. These self-sealing washers are  for use with regular screws, bolts or studs for sealing panels and enclosures having large or irregular clearance holes or slots, and can also be used to seal openings of protruded mounting holes.  Self-sealing washers and fasteners are designed to seal out air, water, lubricants and other liquid or gaseous contaminants. Upon tightening, a seal is formed within the shank and threaded surface of the fastener as well as around the periphery of the washer face.

Features and Benefits:

  • UL & CSA Recognized for NEMA 4x Type 6 Rating
  • UL Tested
  • IP 66/68 Rated
  • Positive sealing under vacuum or pressure
  • Install like a conventional washer
  • Reusable & compatible with all surface finishes
  • Metal-to-metal contact assures fastening and sealing integrity
  • Optional seal materials – silicone rubber, BUNA-N, *Viton®, others
  • Optional black oxide finish with black silicone rubber
  • Uniform, high-strength design – exceeds 100psi internal & external
  • Temperature range of -160°F to +500°F (-106°C to +260°C)
  • Metric sizes available
  • Made in USA

EAO Develops Rugged Selector Switch with Clear Status Indication

Thursday, September 16th, 2010
Milford, CT – EAO Switch Corporation of Milford, CT USA, a premier global supplier
of Human Machine Interface (HMI) Components and Systems, announces their Series 04 hybrid, a rugged, large-lever selector switch. The Series 04 hybrid is an ideal HMI device for any application where it’s critical to show a very clear change in status, such as a door lock. This lever features a tough, anodized
aluminum handle with a comfortable grip. Behind the lever, there’s an immensely strong stainless steel locking mechanism from EAO’s Series 04 range, allowing it to withstand harsh operation, impact, and possible vandalism.
 This HMI device was originally developed as a door-locking mechanism for on-board toilet facilities in rail vehicles. EAO worked in full partnership with Bombardier, one of the world’s largest train builders, to address the needs of both passengers and service providers.  
 
To improve comfort and privacy, passengers require a clear, reassuring indication that the door is locked when the facility is in use. It must be intuitive, attractive, and easy to use by both able-bodied and less able-bodied passengers.
 For Bombardier, the selector switch complements the Series 56 pushbuttons, with their bright yellow bezel, LED halo illumination, and Braille markings. The Series 04 hybrid provides Bombardier with a robust, highly reliable solution that requires minimal maintenance and is resistant to heat, shock, and vibration. This switch, along with the Series 56, is sealed to meet IP67 standards from the front panel and has design features often referenced in disabled passenger access regulations such as RVAR (Rail Vehicle accessibility Regulations) and the ADA (Americans with Disabilities Act).  A self-cleaning, snap-action switching element with gold-plated silver contacts provides a reliable and long service life; silver/palladium contacts may be specified for particularly aggressive environments.

EAO develops HMI Components and Systems for applications ranging from transit systems to industrial equipment. Working closely with its customers and the appropriate regulatory bodies, EAO meets and exceeds expectations for panel layout and ergonomics, system integration, and electro-mechanical design. EAO’s components and systems undergo rigorous testing to assure reliability, repeatability, and long service life. EAO is ISO 9001, ISO 14001, IRIS, and ISO/TS 16949 certified for automotive and other industry requirements.
