Mini Circuit Breaker UL489 Listed 30A D Curve 480Y/277VAC 125VDC 10kAIC DIN Rail Mount Non Polarized MCB Branch Circuit Protection, ControlGear CGMB2D30 (2 Pole D Trip 30 Amp)

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 30 amp breaker is UL-489 Listed for Branch Circuit Protection, delivering reliable performance on standard din rail systems for critical circuits.
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 30 amp miniature circuit breaker is calibrated for a 2 Pole D Trip curve profile. Maximum operating voltage is 480Y/ 277VAC 125VDC with 10kAIC short circuit rating. ControlGear miniature circuit breaker (Model CGMB2D30) 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.
QUALITY TESTING: UL-489 certification for these breakers includes testing for short circuit and overcurrent protection plus mechanical endurance. Manufacturing facilities undergo annual inspection ensuring these miniature circuit breaker products maintain compliance standards for UL-489 branch circuit protection.
