The Schurter 4435.0232 is a thermal circuit breaker designed for overcurrent protection in electrical systems. It is rated for 4A nominal current and can operate at 240VAC or 415VAC (phase-to-neutral), with a rated current range of 0.05 to 12A. The breaker features a rocker actuator and provides a degree of protection of IP40 on the front side.
Electrical characteristics include a dielectric strength greater than 2.5kV at 50Hz and greater than 4kV for impulse voltage (1.2/50μs), with insulation resistance exceeding 100MΩ at 500VDC. The conditional short-circuit capacity is 2kA at 415VAC, and it meets overload requirements per IEC and UL/CSA standards.
The breaker is designed for reliable operation across a wide temperature range, from -30°C to 60°C, and can be stored between -40°C and 60°C. It offers a mechanical lifetime of 50,000 switching cycles, as well as 50,000 cycles under AC and DC load conditions. Vibration and shock resistance are specified per IEC 60068-2-6 and IEC 60068-2-27, respectively.
This thermal circuit breaker is suitable for use in various electrical panels and equipment where reliable overcurrent protection is required. Its rocker actuator provides easy manual reset, and the IP40 front protection helps guard against dust and accidental contact.
