This E-T-A 4230-T110-K0DE-2A is a single-pole, thermal-magnetic miniature circuit breaker (MCB) designed for reliable circuit protection. It conforms to EN 60947-2, UL 1077, and UL 489 standards, ensuring broad applicability.
The breaker features a 2A current rating and supports a maximum voltage of 277VAC or 60VDC for single-pole operation, with higher DC ratings available for series configurations. It boasts a high rupture capacity of up to 10,000A AC/DC, providing robust protection against overcurrents.
Designed for easy installation, it mounts directly onto a standard DIN rail. The thermal-magnetic tripping mechanism ensures dependable switching behavior, while the lever actuator allows for clear visual status indication. Environmental testing includes resistance to vibration, shock, corrosion, and humidity, making it suitable for demanding applications.
Typical applications include protection of cables, motors, generators, transformers, and sensitive electronic equipment such as computers and telecommunication systems. Its construction adheres to insulation coordination standards with overvoltage category III and pollution degree 3.
Voltage ratings depend on standard: UL 1077 1-pole AC 277V, UL 489 1-pole AC 120V/277V, IEC 60947-2 1-pole AC 240V, DC ratings up to 125V (2-pole series).
