Circuit breakers are an essential device in electrical safety systems, providing both circuit protection and fault notification. The 1E30UM is a unique type of circuit breaker, providing a high degree of flexibility, reliability, and cost-efficiency. It is well-suited for applications ranging from industrial, residential, and electrical power systems to motor vehicle and appliance safety systems.

Application Field and Working Principle of the 1E30UM

The 1E30UM is a snap-action, air magnetic circuit breaker. It has a fast trip time, reliable switching ability, and offers high ratings up to 690V AC and 800A DC. This makes it well-suited for applications across a wide range of voltage and current levels, from high-voltage industrial power systems through to commercial and residential installations. It is available in several body sizes to suit different design requirements.

The 1E30UM features an advanced design utilizing a continuous current-sensing element and a permanently-magnetized alloy core. The current-sensing element allows the breaker to measure the rate of rise of current, while the magnetic core holds the breaker in the latched position when power is applied. In the event of an overload or short circuit, the circuit breaker trips by releasing the latching mechanism and breaking the circuit.

The 1E30UM can be used with either manual or automatic resetting. Manual resetting requires the user to press the reset button after the fault is cleared and the power is restored. Automatic resetting will automatically reset the breaker when the fault is cleared, provided that the power is still present. The 1E30UM also features a “short delay” mode, which reduces the trip time of the breaker in applications where a short delay is required before the circuit is disconnected.

The 1E30UM has a unique set of features that make it invaluable in applications ranging from industrial power systems to everyday appliance safety circuits. In addition to its enhanced reliability, flexibility and cost-efficiency, it is also compatible with a wide range of motor control panels, contactors, and control systems. This makes it an ideal choice for applications that require a reliable and efficient circuit breaker.
