Eaton Electrical UL 489/UL 1077 DIN Rail Miniature Circuit Breakers

Eaton Electronics UL 489/UL 1077 DIN Rail Miniature Circuit Breakers are designed for branch service applications. These devices are available with B, C, and D characteristics with UL® 489, CSA® C22.2 No.5, UL 1077, CSA C22.2 No.235, and IEC 60947-2. The circuit breakers include standard ratings of 10kAIC up to 277/480VAC, contact position indicator (red/green), and 17.7mm width of module (per pole). These devices are suitable for branch circuit device protection and thermal-magnetic overcurrent protection and are current-limiting. The circuit breakers are available in two terminal configurations: standard box terminals with multiple conductors and ring-tongue terminals.

UL 489 Circuit Breakers

The circuit breakers are used for branch circuit protection, internal/external receptacles, relays, UPS, external motors, PLC I/O points, computer, and Heating, Air Conditioning, and Refrigeration (HACR) equipment.

UL 1077 Supplementary Protectors

The circuit breakers are used for overcurrent protection within appliances or electrical equipment.

Features

  • Complete range of UL 489 listed DIN rail mounted miniature circuit breakers up to 63A current rating
  • Standard ratings of 10kAIC up to 277/480VAC
  • Select amperages available at 14kAIC up to 277/480VAC and 10kAIC up to 125VDC per pole
  • Current limiting design provides fast short-circuit interruption that reduces the let-through energy, which can damage the circuit
  • Suitable for branch circuit device protection
  • Thermal-magnetic overcurrent protection:
    • Three levels of short-circuit protection, categorized by B, C, and D curves
  • Single-, two-, three- and four-pole configurations available
  • Trip-free design—breaker do not be defeated by holding the handle in the ON position
  • Captive screws do not be lost
  • Switching Duty (SWD)—suitable for switching fluorescent lighting loads (In≤20A)
  • Fulfill UL 489, CSA C22.2 No.5, and also IEC 60947-2 standard
  • For use in applications for which UL 1077 or CSA C22.2 No. 235 are also allowed
  • Field installable shunt trip and auxiliary switch subsequent mounting
  • Separate version for ring-tongue connection (Type FAZ-RT), terminal screws can be removed (on both sides)
  • Module width of only 17.7mm (per pole)
  • Contact position indicator (red/green)
  • Easy installation on DIN rail
  • Possibility for sealing the toggle in ON or OFF position

Applications

  • Convenience receptacle circuits (internal/external)
  • Motor control circuits
  • Load circuits leaving the equipment (external)
  • Heating, Air Conditioning, and Refrigeration (HACR)
  • PLC I/O points
  • Computers
  • Power supplies
  • Control instrumentation
  • Relays
  • UPS
  • Power conditioners
