Molded Case Switches serve as crucial components in electrical circuit management, enabling the switching on or off of a circuit safely. Unlike Molded Case Circuit Breakers, Molded Case Switches do not provide protection against overcurrent faults or branch circuit issues. They facilitate the safe disconnection of primary circuits, proving essential in various industrial applications.
NOARK Electric offers a comprehensive selection of Molded Case Switches, available in six distinct frame sizes: M1 (150A), M2 (250A), M3 (400A), M4 (600A), M5 (800A), and M6 (1200A). These switches support a range of interrupting capacities within 240-690 Vac and 250-600 Vdc, functioning solely as disconnect switches.
Features of NOARK Electric's Molded Case Switches
NOARK Electric's Molded Case Switches come equipped with a range of innovative features

They are designed with a high-quality, compact, modular structure and are backed by a five-year limited warranty, ensuring reliability and durability in performance.
Molded Case Switches in Equipment Isolation
In increasingly complex industrial settings, where automation systems are prevalent, Molded Case Switches are pivotal for isolating machinery from the power source for maintenance purposes.
These switches are often placed within an enclosure close to the machinery, allowing maintenance teams to disconnect the circuit locally without accessing the main power feeder, which may be located at a distance.
Role in Circuit Protection Coordination
Molded Case Switches also play a role in circuit protection coordination. They are used in systems where discrimination is necessary across different installation levels, with the ability to handle specific withstand ratings.
However, it is essential for these switches to be used alongside an upstream overcurrent protection device, like a fuse or a circuit breaker, to ensure full protection is maintained.
Compliance with Standards
Compliance with industry standards is crucial for ensuring safety and reliability. NOARK's Molded Case Switches adhere to UL 489-Listed standards, File No. E355392, and CSA C22.2 No. 5 standards, File No. E355392, confirming their reliability and safety in various applications.
