- UL-489 CERTIFIED: This miniature circuit breaker provides primary thermal overload and short circuit protection per National Electrical Code, Approved by Underwriters Laboratories for Branch Circuit Protection in US and Canada. The 5 amp breaker is UL-489 Listed for Branch Circuit Protection, delivering reliable performance for critical systems.
- MOUNTING OPTIONS: Easily install this circuit breaker by snapping onto a 35mm DIN rail (sold separately). The miniature circuit breaker may also be directly mounted to a panel for all circuit protection applications .
- TECHNICAL SPECS: This UL-489 certified 5 amp miniature circuit breaker is calibrated for a 1 Pole C Trip curve profile. Maximum operating voltage is 277VAC and 60VDC with 10kAIC short circuit rating. ControlGear miniature circuit breaker (Model CGMB1C05) is ideal for control panels, HVAC equipment and all applications requiring safe and reliable circuit protection.
- RAPID RESPONSE: ControlGear miniature circuit breakers are inherently current limiting, interrupting faults within the first half of the AC cycle, while conventional breakers require 1-2 AC cycles. This provides enhanced protection for power and control circuits.
- AVAILABLE ACCESSORIES: Add sophisticated control features with a full line of snap-on accessories, including a shunt trip module, undervoltage release, auxiliary contact and alarm modules, a locking device, and bus bar primary connection system.

FAQ:
Q: What do miniature circuit breakers mount on DIN rails?
A: Also known as IEC miniature circuit breakers, modular DIN rail breakers, or dual-rated UL and IEC breakers, they mount on DIN rails to save space in panelboards and load centers. They’re manually resettable after they trip and include a contact position indicator that shows when the circuit is on or off.
Q: What kind of circuit breakers are in ul 489?
A: UL 489 Miniature Circuit Breakers – FAZ-NA Series. Eaton FAZ-NA Series mini circuit breakers offer optimum and efficient protection for feeder, branch and control circuits up to 40 amps. FAZ-NA series DIN-rail mountable circuit breakers are available with C or D trip characteristics in accordance with UL 489.
Q: What causes a DC circuit breaker to trip?
A: All are thermal/magnetic— breakers trip when heat is generated by sustained, low-level overload current, but will trip quickly when the magnetic field in the coil senses a high-current short circuit. Mount directly to DIN rail. Breakthrough current is the maximum current that the circuit breaker can safely stop in the event of a short circuit.
Q: Can a branch circuit breaker be used downstream?
A: These circuit breakers meet UL 1077 requirements for supplemental circuit protection and are designed for use downstream of a branch circuit breaker. Use them with small transformers, lighting, and control circuits.
