Circuit breakers are devices utilizing a “trip” function to detect and minimize circuit overloads. UPGF6-30421-06 is a type of circuit breaker that utilizes a thermal-magnetic trip mechanism to provide circuit protection. It is an ideal solution for use in smaller commercial and residential applications. This circuit breaker features a single pole, C-Curve, 30A rating, 208V to 240V AC operations, and MCB type test switch.

Application Field

UPGF6-30421-06 is a compact, single-pole, mini circuit breaker that provides circuit protection in both residential and commercial environments. It is designed for use in branch circuits to protect lighting, motors, and other appliances. It is typically used in branch circuit panelboards, wall switches, and fused panels. The breaker is quickly installed and easy to use, yet provides a very high level of protection. The breaker is tested to UL standards and is suitable for load centers, panelboards, and other applications requiring overload and short circuit protection.

Working Principle

The UPGF6-30421-06 circuit breaker utilizes a thermal-magnetic trip mechanism for superior circuit protection. The trip mechanism works by detecting current overloading and heat buildup in the circuit. When excessive current is detected, the trip arm is released, disconnecting the circuit and preventing the overload from causing harm. The heat generated from the overcurrent is also monitored, and when it reaches a certain level, the thermal trip arm is released, disconnecting the circuit from the power source. This helps to prevent damage to the wires and related components.

The unit also includes several protective features, such as a manual reset button, a shunt trip feature, and a direct tripping system. This type of circuit breaker is also designed with an adjustable long-term response time. This helps to better protect against short-term overloads that can occur when starting a motor.

UPGF6-30421-06 circuit breaker is specifically designed to be easy to install and use in small residential and commercial applications. With its small size, intuitive design, and superior protection, this breaker is an ideal choice for circuit protection in smaller applications where space is at a premium.
