Minature Circuit Breakers

Miniature Circuit Breakers (MCBs) are a vital element for circuit protection in an electrical systems. They protect circuits from overloads and short circuits and preventing damage to equipment. Available in amperages up to 63A as well as 1, 2, and 3 pole variants, Noark’s MCBs offer excellent quality in a compact size and are backed with their standard 5-year warranty which makes them ideal for use in a wide range of applications.

Noark RDS1 series non-Fusible Rotary Disconnect Switch complies with UL98 standard and can be used for isolation in AC 600V power systems. During the maintenance of electrical equipment, the product can isolate the equipment from the
power supply, forming a clear disconnect point to ensure the safety of maintenance personnel and equipment.

Manual Motor Starters

Ex9S Manual Motor Starters provide manual isolation, manual motor control, and overcurrent protection. They are electro-mechanical devices combining the functions below in one unit.

• Disconnect for Motor Branch Circuit
• Manual Motor Control (automatic when used with contactor)
• Branch-Circuit Short Circuit Protection (Magnetic Protection)
• Overload Protection (Thermal Protection) – Trip Class 10

The National Electrical Code requires an individual Motor Branch Circuit to be protected by a UL/CSA Listed Fuse, Circuit breaker or Self-Protected Combination Motor Controller.

Contactors and Overloads

Noark motor contactors are designed to handle the most demanding motor control applications, including full voltage non-reversing (FVNR) reversing (FVR) and wye-delta reduced voltage starting.

With amperage ratings from 6A through 1000A, the Ex9C contactor is ideal for any application from HVAC controls, pump control panels and customized control panels for automation systems.

The Ex9C series of motor contactors consists of nine frame sizes, Safety versions for use in safety function applications, and a complement of overload relays and accessories, allowing for maximum design flexibility and efficiency for electrical designers and engineers.

Safety Contactors and Relays

The NOARK Ex9CA Safety Contactor is designed for use in safety
function applications. It offers special features that allow the design
of safe control circuits with current ratings up to 38 Amps.
The Normally Closed (NC) Auxiliary contact is a mirror contact to
the main contacts and is mechanically linked to the Normally Open
(NO) Auxiliary contacts.

• Positively guided mirror contacts/mechanically linked contacts
• Fixed transparent anti-dust cover for easy identification of the device action and prevents manual operation
• AC or DC operating coils
• Integrated body with built in auxiliary contacts up to 2NC and 2NO
• Integrated surge suppression on DC coil models
• 5-Year limited warranty

Soft Starters

Ex9QR5 is mainly used for soft start and soft stop of the 3-phase motor, by reducing the starting voltage and current. At the same time, the soft starter also has the basic function for motor protection. It can be applied on fan, water pump, compressor, ball mill, crusher and other loads.

Available Models range from 15A to 1000A

• Seven kinds of current modes
• Various Protection functions
• 2nd and 3rd motor parameters
• Low-speed forward and reverse rotation function by thyristor adjustment
• Braking and stopping function
• Wide input frequency ranges from 35 Hz to 60 Hz
• Built-in RS-485 communication interface and standard Modbus protocol
• Easy operability: LCD display, friendly interface and convenient operation

Enclosed Breakers

NOARK’s X Series enclosed molded case breakers combine a
UL Listed enclosure with our M Series Molded Case Circuit
Breakers and neutral terminals, when required for 4 wire
systems. The components and assembly comply to UL489 and
CSA C22.2 No.5 standards. Enclosed Breakers are used
wherever a feeder or branch circuit breaker must be mounted
independently. Enclosed breakers are suitable for Service
Entrance as outlined in the National Electric Code and
Canadian Electrical Code.

• Rated Current up to 600A
• Voltage rating up to 600Vac
• NEMA Enclosure Type 1,12 and 3R
• Molded Case Circuit Breakers up to 1200A
• Neutral Terminals for 3P-4W and 2P-3W

Power Circuit Breakers and Non-Automatic Switches

Power Circuit Breakers are available up to 4000 amps and are capable of interrupting ratings up to 100kA at 635 Volts, the maximum voltage can be up to 847Vac. UL Listed and CSA Certified, the A32 and A40 family of products provide design standardization for OEM’s no matter where they do business.

A32 and A40 breakers offer a broad range of available trip units, accessories, and communications options. They are the ideal OEM solution for low voltage switchgear and customized power distribution assemblies used in Data Centers, Standby Power, Industrial, Healthcare and Commercial applications.
