A wide range of features, functionality, and performance for the most demanding applications

Motor protection circuit breakers provide overload, phase-loss and short circuit protection, can be used by themselves as manual motor controllers or with contactors in group motor installations, and can achieve Type 2 coordination for optimum performance. Type E self-protected combination manual motor controllers provide disconnecting means, branch circuit protection, motor control and motor overload protection all in a single device.

Open

  • Only 45mm (1-49/64”) wide up to 20HP @ 460V (15kW @ 400V) in both thermal and magnetic and magnetic only versions
  • UL Listed Type E devices are available
  • For use in group motor installations and certified as Manual Motor Controllers Suitable as Motor Disconnects
  • Ampere Ratings: 0.16 – 32A
  • Designed for optimum performance with Series 300-S09 to 300-S40 Contactors in group motor installations, and can achieve Type 2 coordination in circuits capable of delivering up to 50kA at 460V

Enclosed

  • Two Types: Thermal & Magnetic Trip Elements and Magnetic Trip Element only
  • Ampere Ratings: 0.1 – 32A
  • The lift off ABS Plastic enclosure has an IP55 environmental rating and is CE certified
  • ABS Plastic enclosure designed specifically for the motor protection circuit breaker with integrated ground and neutral connections, and four (4) standard PG16 knock outs (2 on the top and 2 on the bottom)

Accessories

  • Snap-on accessories are easily installed without the use of tools, lowering assembly and installation costs.
  • 18mm wide trip indicating auxiliary contacts can be used to identify the trip cause – overload (1 NO and 1 NC) or short circuit (1 NO and 1 NC), to help determine the type of service/maintenance that may be required
  • Front and side mounted standard auxiliary contacts, shunt release and undervoltage release modules, commoning links, feeder terminal, line side terminal barrier, trip indicating auxiliary contacts, adjustment scale cover, commoning link shroud, mounting foot kit, starter assembly mounting plates, circuit breaker/contactor link module and external operating handle

Optimal Performance and Safety

Designed to provide reliable overload and short circuit protection and are ideal for use in group motor installations where panel space is at a premium and device modularity is required to satisfy virtually any application requirement.

Proven

UL Listed and CE marked, our Series 330 and E330 Open and Enclosed Motor Protection Circuit Breakers are designed to perform in a broad range of applications.

High Fault Short Circuit Current Rating

High fault short circuit current rating of 50kA @ 480V provides safety and reliability in high fault applications.

Removable Markings

Removable/replaceable identification marker, standard on all c3controls’ Series 330 Motor Protection Circuit Breakers, simplifies troubleshooting.

Trip Indication

Trip indicating auxiliary contacts can be used to identify the trip cause – overload or short circuit – to help determine the type of service/maintenance that may be required.

Padlockable Switches

Handle can be padlocked in the “OFF” position with up to three padlocks for extra safety during maintenance.

Easy to Install

35mm DIN rail mounting for fast and easy installation and removal, or panel mounting with mounting feet for more secure installation in high shock and vibration applications.

Self-Protected

Our self-protected devices eliminate the need for upstream fuses and circuit breakers, and they provide reliable motor protection.

Added Safety

IP20 guarded terminals with dual terminal markings prevent accidental contact with live parts.
