They are UL listed and comply with the National Electrical Code (NEC) and Canadian Electrical Code (CEC) requirements for fusible safety switches. The switches also meet the RoHS and WEEE directives for the restriction of hazardous substances in electrical and electronic equipment.
The switches are designed for easy installation and come with mounting screws and a grounding lug. The switches can be connected in series or parallel configurations to provide additional protection to larger electrical systems. The switches also have a rated operating temperature range of -40 C to 85 C, making them suitable for use in a wide range of environmental conditions.
In summary, the Cutler-Hammer 4243H322 and 4143H322 Fusible Safety Switches are essential protective components for electrical systems, designed to automatically respond to overloads or short circuits. These switches feature a rugged, cast copper alloy housing, clear glass cover, and are UL listed and compliant with various electrical codes and directives. They are suitable for a wide range of industrial, commercial, and residential applications and can be installed easily in series or parallel configurations.
